Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
[ "The magnitude of the magnetic force is smaller in Pair 1.", "The magnitude of the magnetic force is smaller in Pair 2.", "The magnitude of the magnetic force is the same in both pairs." ]
B
The magnets in Pair 2 attract. The magnets in Pair 1 repel. But whether the magnets attract or repel affects only the direction of the magnetic force. It does not affect the magnitude of the magnetic force. Magnet sizes affect the magnitude of the magnetic force. Imagine magnets that are the same shape and made of the same material. The smaller the magnets, the smaller the magnitude of the magnetic force between them. Magnet A is the same size in both pairs. But Magnet B is smaller in Pair 2 than in Pair 1. So, the magnitude of the magnetic force is smaller in Pair 2 than in Pair 1.

Paulo wants to get a burger meal that costs $6. Aside from that, he also wants to get a soda which costs 1/3 as much as the burger meal. While on the counter, Jeremy asked Paulo to get him 2 of each item Paulo is going to get. How much will they be charged for their orders combined?
null
24
They are to order a total of 3 burger meals and 3 sodas for Paulo and Jeremy. The cost of a soda is $6/3 = $<<6/3=2>>2. So, the 3 sodas will amount to $2/soda x 3 sodas = $<<2*3=6>>6. The 3 burger meals will amount to $6/burger x 3 burgers = $<<6*3=18>>18. Hence, the total cost for their orders is $6 + $18 = $<<6+18=24>>24. #### 24

Sam has 8 marbles left after giving 3 marbles/person x 2 people = 6 marbles to Sally and Steve. Hence, Sam had 8 marbles + 6 marbles = <<8+6=14>>14 marbles in the beginning. Sam had twice as many marbles as Steve, therefore Steve has 14 marbles / 2 = <<14/2=7>>7 marbles in the beginning.

Based on this information, what is this plant's phenotype for the pod shape trait?
[ "constricted pods", "inflated pods" ]
B
You need to determine the pea plant's phenotype for the pod shape trait. First, consider the alleles in the plant's genotype for the pod shape gene. Then, decide whether these alleles are dominant or recessive. The allele for inflated pods (D) is dominant over the allele for constricted pods (d). This means D is a dominant allele, and d is a recessive allele. The pea plant's genotype of Dd has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, the pea plant's phenotype for the pod shape trait must be inflated pods.

Laran has started a poster business. She is selling 5 posters per day at school. Two posters per day are her large posters that sell for $10. The large posters cost her $5 to make. The remaining posters are small posters that sell for $6. They cost $3 to produce. How much profit, in dollars, does Laran make per 5-day school week?

The profit made for each large poster is $10 - $5 = $<<10-5=5>>5. Each day Laran earns $5 * 2 = $<<5*2=10>>10 from selling large posters. The profit made for each small poster is $6 - $3 = $<<6-3=3>>3. Each day Laran earns $3 * 3 = $<<3*3=9>>9 from selling small posters. Laran makes a total profit of $10 + $9 = $<<10+9=19>>19 per day. For a 5 day school week, Laran makes a profit of 5 * $19 = $<<5*19=95>>95. #### 95

Step 1: Think about each change. Peeling a banana is a physical change. The peel is not covering the rest of the fruit anymore. But both the peel and the banana are still made of the same type of matter as before. Getting a haircut is a physical change. Your hair is shorter after a haircut. But it is still made of the same type of matter. Step 2: Look at each answer choice. Both are only physical changes. Both changes are physical changes. No new matter is created. Both are chemical changes. Both changes are physical changes. They are not chemical changes. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.
