water in a container having 2 mm thick walls having thermal conductivity 0.5.container is kept in a melting ice bath at 0C.total surface area in contact with water is 0.05 m^2.a wheel is clamped inside the water and is coupled toa block of mass M.as the block goes down,the wheel rotates.it is found that after sumtym a steady state is reached in which the block goes down witha constant speed of 10cm/s and the temperature of the water remains constant at 1 C .Find the mass M of the block.assume heat flows out of the water only through the walls in contact
