A woman standing on the surface of Earth has a mass of 70 kg and a weight of 700 N. If instead she is floating freely inside a non-rotating space habitat far from Earth, her mass would be

1) less than 70 kg
2) 70 kg
3) more than 70 kg

and her weight would be
4) less than 700 N.
5) 700 N.
6) more than 700 N.

Question 2

Earth and the Moon are attracted to each other by gravitational force. The more-massive Earth attracts the less-massive Moon with a force

1) less than the force that Moon exerts on Earth.
2) greater than that of the force that Moon exerts on Earth.
3) the same as that of the force that Moon exerts on Earth.

This is in accord with
4) the law of inertia.
5) Kepler's Laws.
6) the conservation of energy.
7) the fact that both Moon and Earth orbit about a common point, the center of mass.
8) the law of action and reaction.
