Two students pull on the opposite ends of a rope, but neither student is able to move the other. Which statement best explains why neither student is moved?

They each pull on the rope with the same amount of force, so the net force is zero.

They each exert the same amount of friction against the ground, so the net friction is zero.

Their forces are not balanced, but gravity keeps them from moving.

The two students have the same mass.

A rock on Earth has a mass of 750 kg and a weight of 7,350 N. If the rock is taken into outer space, how will its mass and weight be affected?

The weight and mass will remain the same because they are not altered by the effects of gravity.

The weight will remain the same, but the mass will change because of the effects of gravity.

The mass will be 76.5 kg, and the weight will increase because of the effects of gravity.

The mass will be 750 kg, but the weight will decrease because of the effects of gravity.
