I forget the exact language and I'm on mobile and about to ... |
How can someone recover files that were permanently deleted from a drive? | Deleting a file is like abandoning a self-storage unit. All the stuff is still there, it is just marked as available.

Why is it easier to tear something like fabric, plastic, or paper once you've "gotten it started"? | When you're tearing something, initially the stress is spread over the entire edge of the material, which in effect dilutes the effort.

Why is it easier to open a plastic bottle when it is at room temperature then when it is from the refrigerator? | You're right. When things get hot they expand, and vice versa, which explains your observation.

A bottle from a cupboard or similar will be easier to open in part ... |
Why do conglomerates often produce multiple versions of essentially the same product? | In a word: marketing. Because the cost is very low for a company to produce the same product, using the same plant, and just slap different packaging on it and sell it at a different price point.

What is a "head" as in units of measurement, is it a literal head (ex. Rin is two heads shorter than John)? | It's sort of an expression, not a literal unit of measurement. If I say, "John is a full head taller than me" what I'm implying is that the top of my head is level with John's chin. But again, more of an expression to say someone is a lot taller than someone else. |

Would a long system of gears transfer power/information faster than light or electricity | I did think about a similar problem a while ago. My idea was to use a very long stick. And transmit information just by moving it a bit forward and backwards. And in contrary to my believe it wouldn't move instant. Apparently when you push onto something it won't just move the whole object but each layer of atoms pushe... |
Why does stirring helps dissolve things faster | It's all about surface area. The actual process of disolving only happens when a molecule of the the stuff that's disolving is next to a free gap between two water molecules.

Why does baking a cookie make it impossible to turn it back into dough? | Mud is not a chemical reaction.It's just adding water to sand. The water creeps between the sand particles making them move around more easily. The more water the more "fluid" it becomes. Baking cookies is a chemical reaction where different ingredients bind together which creates new chemicals. The baking itself remov... |
Why do two images that have the same pixel dimensions have different storage sizes? | Most images are held in a compressed format that works by finding repeatable patterns in the arrangement of pixels. For example, a row of 100 red pixels can be compressed into something like "row 15 is all red" rather than 100 individual pixels each being saved as red. So, the more patterns the compression algorithm ca... |
why is ortho more stable than para hydrogen? | Steric Effects: Electrophile attaches where there is the least amount of steric hindrance.

When a car goes underwater. How do the lights stay on even though the batteries under water? | The water is not a good enough conductor to short out the 12 volt system. After some time water would flood the electrolyte the battery or corrosion at connectors between the + & - wires would short it out. Since this short would be surrounded by a large volume of water it would absorb the heat created and would be rat... |
What makes some gases flammable and others not? | It has to do with **energy states** and **activation energy**. Firstly, to clarify, flame is a reaction with oxygen. Hydrogen 'burning' is Hydrogen reacting with Oxygen to produce water . Since air is ~21% oxygen, when you burn hydrogen in air, it reacts with oxygen. Water has a higher **energy state** than hydrogen, s... |
How does a company like dollar tree or family dollar profit when selling big brand names for much less than the regular price? | Most "big box" discount chains negotiate their own price with the manufacturer.

Why do we tend to crave foods that are terrible for our bodies (e.g. sugar) ? | Sugar is good for our bodies.

Just a simplified way.Would it surprise you, this que... |
how do tires on the landing gears of heavy airplanes withstand the speed and weight of the airplane when landing? | They're big tires, so the force is spread out over a larger area, and they use quite a few tires—a Boeing 747 has 18 tires on it—further distributing the load. They use thick rubber, so they're stronger than your average tire by a pretty wide margin. Even with these, they don't last particularly long. Any given tire wi... |

Why do trams shake and vibrate when they go in cobblestone streets even though they are still on steel tracks? | Without any further information about the situation youre talking about, my best *educated guess* is either 1) trams naturally vibrate due to the motion of their internal mechanism, such as suspension.

If the '08 stock market crash didn't result in the loss of any physical 'money' how come so many people lost fortunes? | Remember, things don't have intrinsic monetary value. Things are only "worth" what other people will pay you for them. This is the fluidity you mention. In some cases, the "fortunes" went to other people. If I had a stock valued at $100, then the market crashed and I sold it for $50 , and the person I sold it to resold... |
Why does this two rail tracks in the Czech-Slovak border are salients | The Vlárský průsmyk station is in the Czech Republic, but the rails that belong to the station are long enough to reach Slovakia.

How come superheated water doesn't appear to be boiling? | Water molecules are terrible at figuring our what state they are supposed to be in. They need some external influence to show them what to do. |
The water that comes out of my shower tap is less than 40˚C, why is there steam? | Temperature is just a measurement of the AVERAGE kinetic energy of the molecules. This means that some molecules have more energy to overcome the vapour pressure to vaporize. Think about water sitting at room temperature, despite it not being 100C the water still undergoes vaporization. Since you're adding energy to th... |
Wouldn't all parasites be killed by our stomach acid? How do tapeworms and other parasites survive though the digestion process? | The egg coating is thick enough to survive the stomach acid.
