Explanation:
pressure=density of water × gravity ×height
=1000×9.8×20=196,000N/m^2
=196000/1000=196kpa which is almost 200kpa
Choice (3) would be one of the objects because when its stretching its waiting to release the energy. Then choice (1) would be the other object because when it rolls the energy stored in the ball would be released when stopped. Therefore there storing the energy until released.
Concept:
Wave: It is the disturbance in which the energy is transferred from one place to another place. During the propagation of the wave, medium particles do not move. They vibrate at their position in to and fro form.
In case of the Transverse wave, medium particles vibrate perpendicular to the direction of the wave while in case of Longitudinal wave, they vibrate along the direction of the wave.
Hence, the best definition of the wave will be the disturbance that transfers the energy from one place to another place.
