Answer 1

A hollow spherical tank is half-filled with oil. If water (denser than oil) is added, the overall centre of gravity will move downward.

Explanation:

Water is denser than oil, so it settles at the bottom of the spherical tank and pushes the oil upward. Since the heavier liquid occupies the lower portion, the overall centre of gravity shifts downward.
