Asked by Jon
The time period in seconds, T, for a pendulum to swing is directly proportional to the square root of its length in metres. A pendulum of length 25cm takes a period of 1 second. What length will take a period of 1.2 seconds?

T = k√L so T/√L is constant.
You want L such that
1.2/√L = 1/√25
