Answer 2

Answer:

A simple pendulum oscillates 40 times in 8 seconds. Calculate its time period.

(a) 0.05 sec.

(b) 0.001 sec.

(c) 0.2 sec☑️

(d) 0.1 sec

Explanation:

Now,

$time \: period = \frac{t}{number \:of \: oscillation \: in \: time \: t} \\ = > \frac{8}{40} \\ = > 0.2 \: sec \\ frequency = \frac{1}{time \: period} \\ = > 5hz$
