Your pendulum clock is perfectly aligned to swing with a period of 1 s on the surface of our planet. Which length does that need? Sadly the moon at a distance of 384000 km and a mass of 7 1022 kg is also attracting the pendulum sometimes. Compute the detuning of the clock. Which new length is required?
