Shows a peddle wheel couple to a mass of 12 kg through fixed frictionless pulleus. The paddle is immersed in a liquid of heat capacity `4200 J K^(-1)` kept in an adiabatic container. Consider a time interval in which the 12 kg block falls slowly through 70cm. (a) how much heat is given to the liquid ? (b) how much work is done on the liquid? (c ) calculate the rise in the temperature of the liquid neglecting the heat capacity of the container and the paddle.
