Question

A body makes 200 vibrations in 0.1 s. What is the frequency and time period.

Answer 1

frequency=200/0.1

time period =1/10 seconds

Answer 2

Explanation:

HEY mate.......

$0.1 \: sec \: produce \: vibrations \\ \\ = 200 \\ \\ in \: 1s \: sec \: produce \: vibration = \frac{200}{0.1} \\ \\ \implies2000hz \\ \\ f \: no \: of \: vibration in \: 0.1 \: sec \: is \: 2000hz \\ \\ \implies \: to \: find \: \\ \\ time \: period \: = \frac{1}{f} \\ \\ f = 2000hz \\ \\ \implies \frac{1}{2000} hz$
