Suppose object A and object B are separated by distance, d, with gravitational force. F, between them. If object B is replaced by object C, which has three times the mass how
does the new gravitational force between objects A and C compare to the gravitational force between objects A and B?

A.)the new gravitational force is doubled that of the original

B.)the new gravitational force is one ninth that of the original

C.)the new gravitational force is tripled that of the original

D.)the new gravitational force is half that of the original

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
