Answer 1

A hollow rectangular box is standing upright. A heavy brick is placed on top of the box. The centre of gravity of the system will move upward.

Explanation:

When a heavy brick is placed on top of a hollow rectangular box, the centre of gravity of the combined system shifts upward. This is because the brick adds more weight at the top of the box, raising the overall centre of gravity of the system.
