Solution
The correct options are
A Potential energy is converted into kinetic energy.
C Potential energy is converted into sound energy.
D Potential energy is converted into heat energy.
The iron block is kept at some height and has potential energy. It is coming down the inclined plane, which means, the potential energy, stored in the block decreases. Some part of the potential energy is converted to kinetic energy. Also the inclined plane is rough so some part of the stored potential energy will be spent in overcoming friction. Friction generates heat and sound. So a fraction of potential energy is converted to heat and sound.
