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)
The Moon has practically no atmosphere, so there is no air
resistance.
The Moon's gravity is much weaker than the Earth's.
The mass of the paper folded into an airplane must be greater than
the mass of the crumpled paper.
The pieces of paper were not dropped from a sufficient height for air
resistance to affect their falls.
