Question

1. Try this.
Take a strong thread of sufficient length. Tie a wooden or metal bob to one
of its ends to make a pendulum. Measure the length of the thread in centimetros
and make a note of it. Suspend the pendulum freely from a support. Now, swing
the pendulum and with the help of a stop-watch record how many seconds are
