A simple pendulum on earth has a period of 1.00 s where the acceleration due to gravity is g = 9.81 m/s2. The pendulum is then taken to Neptune, where the acceleration due to gravity is 1.14g.
(a) Would its period increase, decrease, or stay the same?
(b) Calculate the period of the pendulum on Neptune.
