Question

the time period of simple pendulum is 0.2 seconds.how many oscillation will it comete in 5 minute please answer in solution​

Answer 1

$time \: period = \frac{1}{frequency}$

frequency = 1 / 0.2 = 5 Hz

frequency = no. of oscillations / time

$5 = \frac{no. \: of \: oscillations}{5 \times 60 \: seconds}$

$no. \: of \: oscillaions = 1500$

I hope it helps you
