view available hint(s)
hint 1.
how is weight defined in general?
ones mass
no gravity
rotational effects
no support force

Explanation:

Weight is the force exerted on an object due to gravity and the support force. In space, when an object is in free - fall, there is no normal support force acting on it, which gives the sensation of weightlessness. Mass is a measure of the amount of matter and is not the cause of weightlessness. There is gravity in space, just at a reduced level in some cases. Rotational effects are not the main cause of weightlessness.

Answer:

D. no support force
