An increase in an object's mass is typically accompanied by an increase
in weight. Which of the following best
explains this increase?
A. As mass increases, more atoms result in increased
weight.
B. Anytime weight increases, an object's volume
increases as well.
C. An increase in mass usually means less gravitational
pull.
D. Weight and mass are the same thing.

A

Explanation:

Mass is the measure of the amount of matter in an object. If mass is increasing, the amount of matter is increasing.

Weight is the force of gravity acting on the amount of mass. An increase in mass causes an increase in weight, as weight is gravity times mass.

i think the answer would d
