1. A pendulum consists of a mass m = 0.080 kg hanging from a flexible string of length L. The string is very thin, very light, and doesn't stretch much. It makes small oscillations, with a period of 0.663 s. Find the oscillation frequency of the pendulum. Neglect any air resistance.
(in Hz)
2. Find the period of the same pendulum on the moon's surface. The gravitational acceleration of the moon is 1.67 m/s2.
