A simple pendulum and a mass-spring system each have a time period TTT on Earth. They are taken to the surface of a planet where the acceleration due to gravity is g9\frac{g}{9}9g, where ggg is the acceleration due to gravity on Earth. What are the time periods of the pendulum and the mass-spring system on this planet?
