The period of a simple pendulum, defined as the time necessary for one complete oscillation, is measured in time units and is given by T = 2 where {, is the length of the pendulum and g is the acceleration due to gravity, in units of length divided by time squared. Show that this equation is dimensionally consistent. (You might want to check the formula using your keys at the end of a string and a stopwatch.)
