(a) Your pendulum clock which advances 1.0 s for every complete oscillation of the pendulum is running perfectly on Earth at a site where the magnitude of the acceleration due to gravity is 9.80 m/s2. You send the clock to a location on the Moon where the magnitude of the acceleration due to gravity is 1.65 m/s2. Does the clock run fast or slow on the Moon?
A It runs fast.
B It runs slow.
C Neither, it runs the same as on Earth.
(b) If the clock is started at 12:00 noon, what will it read after a time of 19.5 h has elapsed on Earth? Enter the time to the nearest minute.
