<span>When you squeeze an air-filled balloon, you are decreasing its volume. Imagine a ball going at a constant speed between two walls that are 10 feet apart vs. 1 feet apart. You can imagine that when the walls are only 1 feet apart, the ball will hit the walls more times. Therefore, the answer is A. You are correct.</span>
An induced current is a conducting loop that is exposed to a changing magnetic field. And it is knows as induced current

Hello!
We know that by the Law of Avogrado, for each mole of substance we have 6.02*10²³ atoms, if:
The molar mass of of magnesium = 24.30 g/mol
If:
1 mol we have 6.02*10²³ atoms
1 mole of Mg we have 24.30 g
Then we have:
24.30 g ------------- 6.02*10²³ atoms
x ----------------------- 7.43*10²² atoms
![\dfrac{24.30}{x} = \dfrac{6.02*10^{23}}{7.43*10^{22}}](https://tex.z-dn.net/?f=%20%5Cdfrac%7B24.30%7D%7Bx%7D%20%3D%20%5Cdfrac%7B6.02%2A10%5E%7B23%7D%7D%7B7.43%2A10%5E%7B22%7D%7D%20%20)
