When a metal wire elongates by hanging a load on it, the gravitational potential energy is decreased.

A wooden block of cross sectional area A (in shape of a rectangle) has height h. It is held such that its lower surface touches the water surface in a wide and deep tank. The block is released in this positon. It oscillates for some time and then settles into its equilibrium positon. in equilibrium the block floats with its upper face just on the water surface. Calculate the amount of heat generated in the process assuming that the loss in gravitational potential energy of the system coprising of water and the block gets converted into heat. Density of water is rho .
