1.) The period for the pendulum in a clock is givin by: T(L)=2(3.14)√L/32, where T(L) is the period in seconds and L is the length in ft.
a) Find the period of a pendulum that is 18 inches long
b) find the period of a Foucault pendulum that is 72 ft. long
c) How long is the pendulum that has a period of 7.5 seconds?
Thank you :]
