Physics

A pendulum has a length 1 m and a mass 1 kg. Assume Earth freefall acceleration equal to 10 m/s^2. When the pendulum oscillates,the maximal deflection angle is +/- 1 degree.

a) If the maximal deflection angle doubles, what would be thenew period?

b) If the pendulum mass goes up 100 times, what would be the newperiod?

c) If the length goes up 100 times, what would be theperiod?

d) If the pendulum moves to Moon, what would be the period?
