Question

imagine that kevin can instantly transport himself between planet x and planet y. which statement could be said about kevin in this situation?

kevins weight may change between planet x and planet y.
kevins volume may change between planet x and planet y.
kevins mass may change between planet x and planet y.
kevins matter may change between planet x and planet y

Explanation:

To solve this, we analyze each option:

• Mass: Mass is the amount of matter in an object and is constant regardless of location. So Kevin’s mass won’t change.
• Matter: The amount of matter in Kevin (his mass) doesn’t change, so his matter doesn’t change.
• Volume: Volume is the space an object occupies. Kevin’s physical size (and thus volume) won’t change just by moving between planets.
• Weight: Weight is the force of gravity on an object ($W = mg$, where $m$ is mass and $g$ is gravitational acceleration). Different planets have different $g$ values. So if Kevin moves between Planet X and Planet Y (with different $g$), his weight ($W$) may change.

Answer:

A. Kevin's weight may change between Planet X and Planet Y.
