B.Some of the ball’s energy is transformed to thermal energy.
Explanation: Law of conservation of energy states that energy can neither be formed nor be destroyed but it can only be transformed from one form to another form
A main sequence star becomes a GIANT after it uses up the hydrogen in its core.
A giant star is a star with a large radius and luminosity that is much more greater than that of a main sequence star. A giant star is typically formed when a main sequence star deplete its hydrogen gas content. Giant stars usually correspond to the luminosity class ll and lll.
The oldest fossils would be at the bottom, while the youngest would be closer to the surface.
