Question

If a pendulum makes 10 oscillations in 5 seconds, what is its frequency?​

Answer 1

Answer:

frequency is number if oscillation per second

therefore 2 hz

Answer 2

Answer:

Time period = Time taken by the pendulum/Number of oscillations made by the pendulum.

=  $\frac{5}{10}$ = $\frac{1}{2}$ s

Frequency = 1/Period

= 1 / $\frac{1}{2}$ = 1*2

= 2 Hz

hope it helps...
