h$)$ You are testing a decorative clock, to possibly be manufactured by your Consumer Electronics division, and attach a mass $(m)$ to a string of length $(l)$ to form a simple pendulum. Assuming that the acceleration due to gravity $(g)$ of the earth may have an influence on the period $(t)$ of the pendulum swing, use dimensional analysis to find a formula for $t$ which could possibly involve $m,l,$ and $g.$
