B)An object's weight depends on its volume, but an object's mass does not.

C)An object's weight depends on the force of gravity, but an object's mass does not.

D)An object's mass depends on its volume, but an object's weight does not.

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
