Question

in an experiment to measure the time period of a simple pendulum the time for 20 complete oscillation was found to be the 36 seconds what is the time period of a simple pendulum

Answer 1

the time which the pendulum moves is
how much time the pendulum is the second for example if the pendulum moves 12 times there is 12 seconds

Answer 2

Time period=Total time/Total number of oscillations made

=(36/20) seconds

= 9/5 seconds

=1.8 seconds
