Problem

During a laboratory exercise, a student adjusts a simple pendulum until its time period is measured to be

1.50\,\text{s}

on Earth where

g = 9.8\,\text{m s}^{-2}

. a. (a) Calculate the length of the pendulum. b. (b) The same pendulum is taken to the Moon where

g = 1.63\,\text{m s}^{-2}

. Determine its new time period there. c. (c) Compute the ratio of the lunar time period to the terrestrial time period and comment on the result.
