OK, I have a question here that's part of a homework task I have due tomorrow:
The time taken, t, for a pendulum to swing varies as the sqare root of its length, L. If one swing of a pendulum 98cm long takes 2 seconds, find the time taken for one swing of a pendulum 32cm long.
I know of varaition, direct variation etc, but what do I do in this case? I can't work it out.
Any help is greatly appreciated :)
