Question
List all the forces acting on:
  1. The pulley $A.$
  2. The boy and.
  3. The block $C$ in figure.

Answer

  1. Torque $($angular force$)$ is acting on pulley $A$.
  2. Gravitational force is acting on boy as well pull due to weight of block $C$.
  3. On block $C$ gravity as well force upward due to force applied by boy are acting.

 A copper calorimeter of mass 100 g contains a lump of ice at $4^{\circ} C$. When 520 calories of heat are given to the calorimeter and its contents, the temperature rises from $-4^{\circ} C$ to $-2^{\circ} C$. The addition of another 41540 calories of heat brings the temperature of the calorimeter and its contents to $2^{\circ} C$. Determine the specific heat capacity of copper and the mass of ice present in the calorimeter. Given: Latent heat of fusion of ice $=80 cal / g ^{-1}$ Specific heat capacity of ice $=0.5 cal / g ^{-1}\left({ }^{\circ} C \right)^{-1}$
