A cylindrical tube of card board containing lead shots, is held vertically and then suddenly turned through an angle of 180° so that the lead shots fall to the other end of the tube. The operation is repeated 100 times, the average distance of fall of the lead shots at each stage being 100 cm. Calculate the rise in temperature produced in the lead shots. J = 4.2 J/cal. g= 980 cm/s². Specific heat of lead = 0.03. %3D
