The apparatus show in firgure P11.8 was used by Joule tomeasure the mechanical equivalent of heat. Work is done on thewater by a rotationg paddle wheel, which is driven by two blocksfalling at a constant speed. the temperature of the tired waterincreaseds due to friction between the water and the paddles. ifthe energy lost in the bearings and through the wall is neglected,then the loss in potential energy associated with the blocks equalsthe work done by the paddle wheel on the water. if each block has amass of 1.5kg and the insulated tank is filled with 200g of water, what is the increase in tempterature of the water after the blocksfall through a distance of 3.0m?
