Time to swing. The period T (time in seconds for one complete cycle) of a simple pendulum is related to the length L (in feet) of the pendulum by the formula 8T^2=n ^2 L. If a child is on a swing with a 10 foot chain, then how long does it take to complete one cycle of the swing?
Thanks

    n is not defined in your formula.
