Disks A and B are mounted on shaft SS and may be connected or disconnected by clutch C . (See Figure 10.78 .) Disk A is made of a lighter material than disk B , so the moment of inertia of disk A about the shaft is one-third that of disk B . The moments of inertia of the shaft and clutch are negligible. With the clutch disconnected, A is brought up to an angular speed ω 0 . The accelerating torque Is then removed from A , and A is coupled to disk B by the clutch. (You can ignore bearing friction.) It is found that 2400 J of thermal energy is developed in the clutch when the connection is made. What was the original kinetic energy of disk A ? Figure 10.78 Problem 66.

The figure shows four orientations of an electric di-
pole in an external electric field. Rank the orienta-
tions according to (a) the magnitude of the torque
on the dipole and (b) the potential energy of the di-
pole, greatest first.
