51. assignment (simple pendulum)

The earth's acceleration due to gravity varies from 9.780 m/s2at the equator to 9.832 m/s2 at the poles. A pendulum whose length is precisely 1.000 m can be used to measure g. Such a device is called a gravimeter.

How long do 100 oscillations take at the equator?

How long do 100 oscillations take at the north pole?
