Question1

The period of a simple pendulum, defined as time necessary for one complete oscillation, is measured in time units and is given by
T=2π√(l/g)

Where l is length of the pendulum and g is the acceleration because of gravity, in units of length divided by time squared. Show that this equation is dimensionally consistent. (You may want to check the formula using your keys at the end of a string and a stopwatch.)

Question2

According to theory end correction for a pipe is approximately L=0.3186D, where D is diameter. find actual length of a pipe open at both ends that will make a middle C(256Hz) as its fundamental mode for pipes of diameter D=1cm,10cm and 30cm.
