Question

1. A simple pendulum completes 40 oscillations
in one minute. Find its (a) frequency, (b) time period.
​

Answer 1

Answer:

0.667 hertz is frequency

1.5 seconds is time period

Answer 2

$\huge\star\mathfrak\red{{Hey Mate...!!}}$

(1) Frequency = oscillation/Time

Frequency = 40/60

Frequency = 2/3Hz

(2) Time period = Time/Oscillation

Time Period = 60/40

Time Period = 3/2sec
