What's the circle thing at the top of clipboards for? | This is probably going to get deleted for being too short of an answer for ELI5 but it's simply to hang the clipboard. For example You can be a business with a good few people working for you. There's a board on the wall thay could have the employees names at each hook then you hang up the employees list of jobs for th... |
Why do you constantly hear a almost quiet, but high pitch noise, especially noticeable when you’re in a quiet room? | I didn't hear anything before I read this. Once I was done, all I can hear is this deafingly loud high pitch tone lol. Odd how the thought can provoke it |
How do garbage dumps contain trash or prevent further pollution? | I'll address trash blowing away first. For that, landfills do their best by compacting trash as soon as possible after it is dumped and by putting up tall nets around the active part of the landfill to catch as much of what blows away as possible. This is not a perfect system and some stuff does blow away. The protecti... |
how are we able to clearly visualize images in our head of things we have seen and also have never seen before? | I found it interesting recently that I can create images in my mind of imaginary people I have definitely never met before including detailed faces and all their mannerisms. No doubt an amalgamation of different people i have met but still an impressive mental feat. Not that I think I'm special - it never occurred to m... |
Why doesn’t alcohol freeze like water? | Despite how common water is, it's actually a pretty weird substance . Other people have given more detailed answers, but the question is more the other way round-why doesn't water freeze the same way as other liquids. It's very polar, and this causes unusual reactions. |
How does bruteforcing work? | I feel there is an important distinction to be made here: You can run anything you want on your computer, and in principle, everything your computer does is controlled by you. A foreign computer is controlled by someone else. You can maybe speak to that computer, but it's up to the owner of that computer to decide what... |
The weird taste in your mouth after waking up | Also, just a side note: that's kind of a bad thing to have happen. That means either there is enough food residue in between your teeth and in your mouth that bacteria just feasted on it and multiplied. You know how underarms smell bad because of bacteria? That's what happening inside your mouth. Bacteria loves a wet d... |
Why does urine always come out yellow (or clear) | The yellow color is from a byproduct of breaking down red blood cells. Your body goes through a ton of these. A separate byproduct, by the by, is responsible for making poop brown. There's no direct connection between what you consume, and what you pee. It's filtered from your blood. The only way stuff you eat can colo... |
What is so special about primes? | The important thing about primes is not that they can't be divided by other numbers, but that they make up other numbers, uniquely. This means that by studying prime numbers and their properties, you can study all numbers and their properties - tons of theorems of number theory start with taking the unique prime factor... |
If oil is hydrophobic, how can it perform capillary action if capillary action operates by using hydrophilic bonds? | hyrdophobic just means doesn't mix with water.. it's still a liquid. I'm pretty sure that capillary action is about most all liquids and not just water I'm sure their are some exceptions depending on the material that is being capilarried and the type of liquid. |
What happens with all the profits the Fortune 500 companies make? | Some it goes to investors, in what's called dividends. Some of it goes to employees, in the form of bonuses. Most of it goes into operating accounts. When you hear Company A bought Company B for $zzzM, that's them spending that money. When you hear of a company building a new plant or putting new machines in a plant, t... |
Why does Western toilets still use toilet paper and not have a bidet like Asian toilets? | This is subjective, and that's not allowed on ELI5. Questions like this are better in r/nostupidquestions. |
How does voting in the Midterm election work? | The other replies gave good answers for official places, but if you're looking for a nice simple outline, i find _URL_0_ to be super useful in that regard. Searchable, and directs you to other places to get official sources |
Why can't we just scratch all billions of debt countries have and 'start over'? | Because You'd also then de facto erase many peoples retirement plans, savings, and their hard earned money. |
Why can drinking heavily sometimes cause you to lose your memory of events the night before? | Alcohol has a peculiar effect on the body, specifically on neurons. The transmission from one neuron to the next can be impacted at various levels. The level you're thinking of is strong enough to hamper the transmission from the hippocampus, which moves short term memory into long term memory. Can't really specify muc... |
How does a thermostat accurately sense the air temperature in a room when it's installed inside a small space heater that's generating heat? | It really doesn't matter where the sensor is. Even if you put the sensor directly in the hot air plume of the outlet. People might still be cold and will just turn the heater up despite the number displayed. It's just relative. It's a matter of calibration. What I mean is..if your temp sensor is on the bottom of the he... |
Why is the skin on bald men's heads shiny but skin everywhere else on the body is dull? | Additionally, there's more light getting reflected from an overhead source. For example, bare shoulders are usually shinier than bare arms. |
How can warfare have rules when the whole point of war is to kill each other? | If you don't want your medics to get shot at and your water supply poisoned, don't do these kinds of things either to your enemy. Wars have strategic goals, and total extermination is rarely one. If you use cruel methods, so will the enemy. |
Difference between AED and manual defibrillator (I think that’s what it’s called.)? Do both reset incorrect heart rhythms or can either restart a flatline? | The two are functionally the same. Both correct the hearts rhythm. The AED checks the heart rhythm and then let's the user know if it is necessary to shock the person and uses voice commands to tell the user how and when to administer the shock which allows someone who isn't a medical professional to use it. The manual... |
Why is pee yellow when you are dehydrated? | It's all about dilution. Your pee is always the same color unless you're having a medical condition that makes it dark colored. |
How does adding different gears make this wheel spin faster? | When a wheel spins it has power. And that power is made of torque and speed. If you have more speed then you'll have less torque, but still the same power.An example of what torque is is how easily or difficult it is to stop the wheel from spinning. If it has low torque, then that wheel with all the gears at the end mi... |
Why do recycling plants throw away dirty recyclables? Why haven't they been able to find an efficient way to cleanse them on their own? | they can, it's just more expensive which defeats the purpose because then you will have to sell it a a price to much to be woth buying. |
Why do some songs sometimes feel like they're faster or slower than they actually are? | A song may be 60 beats per minute, but if the song is all 1/16th notes then you are playing 960 notes per minute. Where as a song that is 100 beats per minute but is 1/4 notes is 400 notes per minute. How fast a song is isn't just the tempo, but also the time signature and how the notes are written.I think it has to do... |
why can't you connect multiple wireless headphones to the same phone via bluetooth | The type of connection you're using must allow for multiple instances of that connection on a piconet. This is easiest to explain by example. You can only have a single Bluetooth audio connection for music streaming. The reason for this is that the A2DP profile for audio streaming is designed to have only a single conn... |
Why does cold weather give us the sudden urge to urinate? | Interesting side note: if you're going to be exposed to the cold for a long period it's best not to urinate. A bladder full of urine is a good internal heat reservoir due to the latent-heat capacity. However, do not hold it for such a time as to 'wet yourself' as it will rapidly cool on the outside of your body, drawin... |
why do anti-depressants have side-effects (headaches, dizzyness, nausea,...) | It's because you stopped for the 4 days, u were getting used to the regulation if the medication and suddenly stopped it. SSRI's alter the neurotransmitters in the brain to help its function and improve quality of life, stopping it suddenly after getting it up to appropriate concentrations will cause side effects that ... |
the difference between piston plane engines and car engines | A plane engine is built for power density, a normal car engine is built for reliability For a daily drive you really just want moderate performance in a reliable package. It doesn't particularly matter if the engine is 110 or 130 horse power or if its 10 kg heavier, it'll still work just fine for a daily driver. For a ... |
Why does the sound of my voice and the sound of my voice on a recording sound so different? | If I remember correctly it's because of how sound travels. When you listen to yourself in a recording the sound is traveling through free air so it's a little closer to your actual voice whereas when you hear yourself regularly, the sound is traveling through your head not the air. Recordings aren't 100% accurate so do... |
How are we able to study space so extensively? | Temperature we can estimate based on the size of the star and it's radiation output, along with the planet's orbital distance. Composition of planets is harder. Sometimes if a planet passes in front of its star, we can measure the light that was filtered through the atmosphere and see exactly which frequencies were fil... |
how do people get drunk from absorbing alcohol through their rectum or vagina? | Your skin blocks a lot of chemicals from getting into your blood. It's very good at it. Chemicals will have a much easier time getting into your blood, and then via the blood, to your brain , if you put them where you DON'T have skin. In the mouth, in the stomach , in the nose, in the eyes, in the rectum, in the lungs ... |
If my feet are cold, then why do they sweat? | Sweating doesn't just happen in response to heat. There are a number of reasons why we sweat, and even more why you might sweat from your feet. & #x200B; 1. It is possible that the sweat is coming first, and then it is causing your feet to feel cold. That it - you notice the cold *after * the sweat has already cooled i... |
What are the differences between the functions of a President, Chairman, CEO, CFO, and COO in the corporate structure? | One thing I'd add that most of the other answers didn't mention. **The CFO is more than just the accountant-in-chief.** He or she is responsible for the company's interaction with capital markets. They are responsible for overseeing the operation when the company does an IPO, issues secondary stock offerings, issues bo... |
Why is it so difficult to memorize some of the things which we really need to whereas somethings we easily memorize without even putting in the effort to do so? | TBH this is just one of those things. You're only thinking that because you notice it. There's a billion things you remember that you had to remember for school. But you spend like 70% of your life outside of school so obviously a shitload of other things happen then too and you just happen to remember a thing here and... |
Why have we not been able to domesticate large breed felines ( lions, tigers etc.) like we have with large breed canines ( Mastiffs, St. Bernards etc.)? | All domesticated animals share a few common traits, one of which is preexisting in a hierarchical society in which humans supplant the alpha by controlling feeding and breeding. Big cats, with the exception of lions, don't have these kinds of family structures. In the case of lions, they get really big and have a numbe... |
Why do popsicles freeze in such a "soft" way that it's really easy to bite through them, but ice itself freezes so darn hard? | When water freezes into a hard ice cube, all of the molecules are forming into a big strong block. You can imagine that the water molecules are each a little lego brick, and as they freeze they start to snap together automatically to form a big solid block. & #x200B; Popsicles and ice cream have lots of sugar in them, ... |
How come socks prevent your feet from sweating when it seems like the extra layer should just make them hotter? | Socks, and clothes in general, provide temperature control by providing air buffers and absorbing moisture. This works both ways, to help protect you from high and low air temperatures by providing a buffer that keeps that temperature away from you, and by trapping more moderate temperatures close to you body. The clot... |
Why does North America need Honey Bees? If they aren't a native species then couldn't we survive without them? | I remember reading a while ago that the settlers introduction of the honey bees actually drove some of the native pollinators to extinction and that loss of native pollinators killed off some of the native plants that didn't attract honey bees.AS other said, most native species would be peachy. The non-native would suf... |
What exactly is the significance of pi (the number) | If you draw s circle no matter how big, it's length around the edge will always be 3.14 times the length of it's centerline |
How do headaches work? | Doctor here: It depends upon the headache. * Tension type headaches, which are the most common kind, exist because of muscular tension that causes pain.* Migraine headaches are caused by an interaction between your nerves and blood vessels.* Cluster Headaches are thought to be caused by nerves being exposed to certain ... |
We have free Wifi on Trains, Ships, Buses, Metros etc. What makes it so difficult to have free Wifi on airplanes? | We might have wifi on all those modes of transport, but it is rarely free to the majority of the world. The cruise I just came back from was AU$2/MB for cell-based wifi, or AU$134 for the ship's wifi for the 8-days. |
Why can some meats be consumed while not fully cooked | All depends where the meat came from. As long as theres no parasite in the meat you could pretty much eat it raw. Not all chickens have salmonella but its easy to contaminate in a factoey setting. Rgeally sick and in. The shower rn so i may be wrong on this but if you are very aware of that chickens life and it doesn't... |
How do ISPs operate and what are the things required to start an internet service company? | Mostly, being an ISP is owning the infrastructure. A tier 1 ISP owns every bit of line their services run over, a tier 2 owns some, but rents a bit from other companies and a tier 3 doesnt own any and rents it's all from other companies. It's like owning a house vs having a timeshare vs renting an apartment. Essentiall... |
What's to stop us from just putting solar panels on every flat surface possible? | Regarding the edit: > couldn't we just put clear plexiglass or something similar over them to prevent wear and tear? They're already covered with glass. The problem is that the cells themselves degrade as they produce electricity, some events will break the protective layer, and you still need to maintain the protectiv... |
the difference between first past the post vs Proportional representation systems | Imagine you and your friends live in the suburbs and there's no food in the house. You decide to get food delivered, but naturally you don't want to pay for delivery from multiple different places. So you get together and vote on what restaurant you want, and whatever place gets the most votes wins. Say Alice and Bob v... |
What does a PoE/Power-over-Ethernet switch do? | Generally, Ethernet is used for standard communication across the network and the end point device uses its own power source. Such as an AC adapter plugged into an outlet. Power over Ethernet allows for end point devices to use Ethernet connections for power. [Edit] Usually around 44-57 VDC. This is very useful for man... |
Why do not we remember what we have dreamed of when we wake up? | Does anyone know why sometimes I remember dreams I had years ago and hadn't reremembered or thought of since having them? Dreams be weird. |
the Van Allen belt and how we surpassed it on our way to the moon | It isn't a physical impediment, see focused radiation trapped there is still very thin. It passes no real risk to most electronics, especially for the short duration of exposure. Apollo era electronics are not very sensitive, using large robust components in comparison to modern materials. As for biological risks, astr... |
What stops the flame travelling back down the gas pipe on a gas hob? | For one, there typically isn't oxygen in the pipe, so there can't really be an explosion. *However*, there is also typically a device installed on the line called a flashback arrestor, which ensures that gas only travels in one direction, and that shocks, flames, and high temperatures don't travel back up the line. |
What Are The Principles Of Chicago School Economics? | Chicago school economics is where you pretend that markets are always perfectly competitive, only profits matter and empirical data doesn't count, especially when it interferes with your preconceived ideas.Chicago school economics involves a heavy emphasis on how things would be in an "efficient world" and an understan... |
why do some countries have such superior internet speed and connectivity compared to others? What are these speeds based off of? | I can't speak to other countries but here in Australia our internet speed is largely based on how fast our network technician can turn the crank on the internet box. Speed varies generally based on forearm strength of the operator. Sometimes I can load any webpage in under 12 minutes which is why the majority of my sal... |
How do all the animals survive just fine by eating (mostly) one food while humans need a very diversified diet? | A big thing is that human bodies can't synthesize vitamin-C. Whereas most animals can. One of our primate ancestors happened to get a mutation which lost that ability. However, humans can live just fine on very restricted diets. The problem is that modern day unbalanced diets tends to be exactly the *wrong * kind of fo... |
If Freud was so wrong then why is he still taught in nearly every psychology class? | One of Freud's big theories was that everybody has a subconscious mind and that talking to people about what they think might require reasoning about unseen and unknown mental processes. As far as I know that hasn't been overturned. Is there anyone here who doubts their mind has subconscious activity? |
What are NFL coaches writing during a game on the sidelines? | They're writing down exactly how hard they're going to cut you next season, *Kelvin Benjamin*. |
Does rubbing alcohol actually kill germs on surfaces? | Alcohol disrupts many essential functions for bacteria, although it is unclear which of these disruptions lead to cellular death. Probable effects: * The most accepted view is that alcohol affects the lipid cell membrane.\xa0 Alcohol changes the behavior of all membrane proteins by changing mobility in the membrane.\xa... |
How do large corporations get away with paying less tax than they owe? | Hiding it mostly. Like not reporting the profits. That plus they can send the money to other countries which then send it to other investment which then send it to someone else, and so on. It's out in so many different things that following it becomes a nightmare and hard to trace. |
Does listening to music on full volume damage your ears if the sound is reduced by a loud ambient noise. | The ambient noice doesn't reduce the music volume, it adds to it. This increases the total volume and is more likely to damage your eardrums. |
Why are insanely huge debts owned by countries never considered a big deal? | It's like how you can have a mortgage for hundreds of thousands yet you may not have the money to pay it back right now. To the lender, they dont really mind as long as the borrower can afford the repayments. Remember that the repayments will have interest, so lending money is a great way to make money. In short, it's ... |
Why isn't there an ad blocker which still generates revenue for websites? | The *actual amount of money* advertising companies are *willing to pay* for ads does not depend on the number on clicks. It depends only on the number of sales those ads bring. Fake clicks don't increase the number of sales = > they won't increase the amount of money that enters the system = > they cannot increase payo... |
What's the difference between a wireless access point, a Wi-Fi extender and a bridge? | An access point generates a WiFi network and connects it to a hard wired network which provides the connection to the internet A WiFi extender connects to a WiFi network and repeats some messages to extend the range. If the first WiFi network doesn't have an internet connection then the extended one won't either. A WiF... |
How do escalators maintain the same speed regardless of how many people are on them? | There is a motor always running at the same speed ~1800 rpm attached to a gearbox to slow down the rpm's and create torque. The motor is large enough to carry a fully loaded escalator. It will just draw more amperage when fully loaded than when empty. |
Which of the two types of weapons, chemical and biological, is more lethal and effective in the long run? | This is an absolutely impossible question to answer. There are way too many variables to consider. There are many different types of chemical and biological weapons. It depends on the specific agent, how it's deployed, where it's deployed .etc. |
what's the difference between internet and www? | If you're in a city, the internet is all of the roads, houses, and buildings. The www is just the public-facing businesses.* Internet is the network of computers. It allows you to view data on some computer somewhere else.* WWW is just *one* of the services you can use on the internet. E-mail is anotherThe "Internet" i... |
Who are those guys with the yellow tripods and what are they measuring? | they're survey crews. They're basically measuring the land - how far from point A to point B and their difference in elevation. This allows engineers to build detailed maps of an area for use in building roads, bridges, drainage systems, building foundations, etc. |
How were pigeons taught to deliver messages to people in the midievil times and how effective were they actually? | This is a common misconception about carrier pigeons, the idea that your pigeon just knew where to go. In reality the way carrier pigeons worked is that they were most often kept at one location so they learned it to be their home, let's say Location A. When someone who might want to send you a message left Location A ... |
When giving mouth-to-mouth, how does the other person receive oxygen instead of CO2? | You don't absorb all of the oxygen that you breathe in so you're giving what you breathe out to the person who isn't breathing. But, most CPR classes are now teaching compression only technique, so most people don't learn how to breathe for someone any more. |
how do skiers survive such high drops without dying or severely injuring them selves? | Extreme skiers are able to survive drops like that because they don't stop moving; if they dropped onto level ground -- especially level ground not covered with feet of snow -- they'd get injured. |
Why is the binary system used in computers & How data is converted into signals? | Because the easiest way to measure a state is if it is either on or off. That's 2 states and so it has to be represented with binary. Technically, we can have multiple states by measuring the power of the current state. For example, you could do trinary by measuring if it's at full power, off, or somewhere in between. ... |
If someone has a limb amputated, what causes them to feel like it's still there after it's gone? ie. ghost limbs? | The homunculus, or little man, in your brain. It's literally a map of your body imprinted in the neurones of your brain, even if you lose a limb, the neural connections are still there. It can take a very long time for your brain to rewire itself. |
Do antibiotics that kill certain bacteria but leave other bacteria intact, provoke a change in behavior among surviving bacteria? | Not really. Antibiotics target a certain skill belonging to certain bacteria, which is the basic difference between classes of antibiotics: what capacity of the bacteria are they targeting? Which is why the doctor usually doesn't need to know exactly which bacteria you have, but have a good idea of what kind of bacteri... |
What makes something "biodegradable"? What are the conditions necessary for something to biodegrade? | Everything is made up of different atoms, which are very very small pieces of things. And these group together to form different chemicals. They're held together by special bonds between the different atoms and groups of atoms. The type of bond depends on the type of atoms. Some of these bonds are easy to break, and so... |
How does a suppressor work on a gun? | Didn't see this posted in the comments, but a sub sonic round fired through a suppressor will be drastically quieter than other rounds fired through a suppressor. Example: [_URL_3_]", 'You have 2 things that make noise1 is the projectile breaking the sound barrier2 is the rapid expansion of hot gasses. 1 can only be re... |
How do disease eradication campaigns (e.g polio, guinea worm) get accurate and prompt information about disease outbreaks from impoverished, rural, and isolated areas? | How do you know it's accurate? These diseases are pretty nasty, but there could be many carriers who don't know they have it. What you see here are the verified cases, the actual cases would be some multiple of that. |
What is that fizzing sound in the back of my neck when I'm super hungry? | Huh, I thought I was just a weirdo, you guys feel it too? I've never really thought of it as fizzy feeling but it totally is. I've always just felt uncomfortable when it happens. |
Why are human babies so weak at birth and other animals are fully functioning at birth? | Brains require a lot of energy and time to get right. In so doing, the baby isn't capable of the same kinds of actions the parents are in order to survive. Compare to equines and other prey animals who are mobile very quickly after birth. However, despite babies not being very functional at birth, they're too large to ... |
If my phone, TV, and PC are all sent the correct time from an accurate central location, how come they don't show the same time? | Those 'time update' messages are only sent periodically. In the meantime, the device must keep track of time on its own. To do that, some sort of oscillator is used. Oscillators drift over time; some more than others. They are also affected by things like temperature and vibration. Since each device uses different osci... |
Why are Anxiety and Depression so common and hard to overcome? | We've created a society we're not designed to live in: massive inequality, long commutes, few green spaces, loneliness, stress. Mass media constantly shows us pictures of people that are more successful and important than us, telling us to work harder, exercise more, and buy the right kind of things to be like them. We... |
Why is it mandatory to have seatbelts on private cars but on public transport there aren't any seatbelts and somehow everyone's fine with that? | I've been on a fender bender while on a bus. Didn't even feel it. I only found out it happened because we stopped and it was announced. Otherwise, buses likely will win most car crashes anyways. Only other things to worry about is getting t boned by a runaways 16 wheeler. At that point, seat belts will pretty much amou... |
Why is it that when putting somebody on speaker phone when calling them, the microphone doesn't pick up their voice - resulting in them hearing themselves talk? | The phone knows what signal it is outputting to the speaker, and knows to subtract that signal from what it's getting from the microphone. When the phone doesn't know this, you get an echo - this happens when people call in to the radio, and leave their own radio playing during the call. |
How does Google know which image to output only with words? | It's nothing to do with machine learning or anything like that. Google Image search just searches for images that appear around matching text. Most images on the web are captioned or relate to the text around them. Some images have meta tags that describe them . This makes it possible for the Google engine to guess wha... |
How does a tiny amount of salt create such a drastic effect on the taste of food? | It's really important that you don't drink salt water like its regular water. Like super important - you can die. But also your nervous system needs sodium and potassium to function, so your body evolved to like getting a small amount of salt but really really hate getting a lot of salt. This crazy scaling means that w... |
why do Americans call trucks (18wheelers) semi’s | The name comes from *semi-trailer*, which is a trailer that doesn't have a front axle . Over time, the name came to be shortened and used for the combination of the cab and trailer instead of just referring to the trailer specifically, as tends to happen. |
Apart from the obvious fact that gold is given value by everyone and THEREFORE has intrinsic value, what exactly is the big deal about Gold? | There is a decent summary [here] TL:DR for picking an element for money * it can't be a gas* it can't be corrosive or reactive* it can't be radioactive* it must be rare enough to be valuable, but not so rare that it's impossible to find The first three narrows it down to around 30 elements. The last one is the kicker. ... |
differences between using a loopback connector and my loopback address | Yes, that's the point. To use a loopback connector you have to remove the network cable and plug the loopback dongle in instead. Using the loopback address uses the network cable and switch to approximate the same thing, without disturbing the wiring. If the loopback address doesn't work and the loopback connector does... |
Why do some states require you to reveal your identity when you win the lottery? | Reduced chance of fraud. As well as showing people proof that someone actually won and it wasn't a scam all along.The idea is that makes it more difficult to just always have the same certain group of people win. Less fraud', "With the ever-increasing prizes and concerns about personal safety, I have learned that if yo... |
How does a railgun work and why are there no flames while the projectile is in the air and then lots of flames and sparks on impact? | Actually no one is mentioning it, but most railguns do launch with a lot of flames. Even though there is no combustion to launch the projectile, at initial launch the round is traveling fast enough to turn the air around it into superheated plasma. Here's the longer video of that gif. [_URL_1_] |
The 'Rail-Gun' and why it's such a big deal? | BAE Systems has made a 32 megajoule rail gun that can launch a 7lb projectile up to about Mach 7, range of about 110 nautical miles. Destroys it's target with pure kinetic energy. No explosives. All by magnetic acceleration. Think of a modern roller coaster launch But at 7 times the speed of sound. |
what is kN and what is the difference between kN and nm? | One Newton of force can make 1 kg object accelerate by 1 m/s after 1 second of acting on it. So kN is the same but with 1000 kg object. I assume you meant Nm which is the torque that 1 Newton creates on a 1 m long arm. |
How can MLB pitchers throw so hard/fast? Do they have some type of special muscle development? Or is it just natural ability? | Generating torque/whip with your arm, given you have strengthened all the collect muscles allows you to get I think it's over 1000 degrees of rotation per second. As a college baseball pitcher I feel like I should know more but yeah lol |
Why is it that If you drop something electrical into a pool it affects the whole pool, but if you drop something electrical into the ocean, it dosent electrocute the whole ocean | Simply - it does affect the whole ocean, but the effects at any distance from the device would be very small. When an electric device falls in water, electricity flows from the high-voltage live parts inside the device to the low voltage grounded parts. Now, most of it will flow almost straight across, because that is ... |
Why is it possible for our bodys to radiate heat to a point we don't need protective clothing? I.e. joggers in winter | It's not really about how much heat is being radiated, it's about keeping your core temperature constant . Exercise uses chemical energy to do work. Almost every time energy is converted from one form to another, some energy is lost to heat. In the case of the human body, calories of chemical energy in glucose are comb... |
Why does it take so much speed to go into outer space? Could we just build a elevator out of steel cables and pull ourselves to space? | > There is an art, it says, or rather, a knack to flying. The knack lies in learning how to throw yourself at the ground and miss. Getting to space is really easy, its only 100km up. But if you want to stay in space you're going to need to travel fast enough to miss the ground on every pass or you'll end up back at gro... |
How does a liquid gel tablet of pain reliever work in your system? | The main questions have been well answered. I'll just clear up a few. Injecting gel caps: those are formulated to be ingested and be metabolized by the liver before becoming effective, so by injecting it would actually make it take longer to be effective when you eat something, all the absorbed stuff goes directly to t... |
How come we like salt in our food, but can’t stand salt in drinks? | I'm gonna guess it has to do with some kind of warning that we're not supposed to drink salt water.Idk, but in Asia salt is quite popular in soda , of course more sugar but a hint of saltyness.
