An astronaut drops two pieces of paper from the door of a lunar landing module. One piece of paper is crumpled and the other piece is folded into an airplane. Why do the two pieces of paper land on the Moon’s surface at the same time?(1 point)
1 The mass of the paper folded into an airplane must be greater than the mass of the crumpled paper.
2 The Moon has practically no atmosphere, so there is no air resistance.
3 The Moon’s gravity is much weaker than Earth’s.
4 The pieces of paper were not dropped from a sufficient height for air resistance to affect their falls.
