A very light rigid rod with a length of 0.692 m extends straight out from one end of a meter stick. The combination is suspended from a pivot at the upper end of the rod as shown in the following figure. The combination is then pulled out by a small angle and released.
(a) Determine the period of oscillation of the system.
(b) By what percentage does the period differ from the period of a simple pendulum 1.192 m long?
Establish an average acceleration
Calculate the energies and wavelengths of the 3d to 2p transitions, taking into account the fine structure of both levels

In each cycle of its operation, a refrigerator removes 10 J of heat from the inside of the refrigerator and releases 38 J of heat into the room. How much work per cycle is needed to operate this refrigerator.
A student weighing 800 N crouches on a scale and suddenly springs vertically upward.His roommate notices that the scale reads 900 N, With what acceleration does he leaves the scale
what will be the frequency of vibrations. At one instant a bicyclist is 70m due east of a park's flagpole, going due south with a speed of 15m/s. Then, 19s later, the cyclist is 65m due north of the flagpole, going due east with a speed of 14 m/s.
