Astronauts on a distant planet set up a simple pendulum oflength1.2 m. The pendulum executes simple harmonic motion andmakes 100complete oscillations in 430 s. What is the magnitude oftheacceleration due to gravity on this planet?

1. A simple pendulum is swinging back and forth through asmallangle, its motion repeating every 1.40 s. How much longershouldthe pendulum be made in order to increase its period by 0.12s?
