Question

a feather and a brick are dropped from the same height in a vacuum chamber on earth. which object will hit the bottom first? feather brick both will hit the bottom at same time not enough information this is a required question

Explanation:

In a vacuum, there is no air resistance. The acceleration due to gravity ($g$) is the same for all objects near the Earth's surface, regardless of their mass or shape. The time taken to fall from a height $h$ is given by the formula $h = \frac{1}{2}gt^2$, which can be rearranged to $t=\sqrt{\frac{2h}{g}}$. Since $h$ (height) and $g$ (acceleration due to gravity) are the same for both the feather and the brick, the time $t$ taken to reach the bottom will be the same for both objects.

Answer:

C. both will hit the bottom at same time (assuming the options are labeled as A. feather, B. brick, C. both will hit the bottom at same time, D. not enough information)
