Question

2 min and 48000 oscillation
Find time period

Answer 1

$\textbf{\huge{ANSWER:}}$

$\sf{Given\:that:}$

=》 The Time taken is = 2 minutes
Converting it from minutes into seconds, we get : 2 × 60 seconds
Therefore,
=》 $\tt{Time = 120 seconds}$

=》The total number of oscillations = 48000

By formula, we know that:-

Time Period = $\frac{Time\:Taken}{No.\:of\:Oscillations}$

Put the values in the formula;

=》 Time = $\frac{120}{48000}$

One more step, and you'll get your answer:-

=》 $\textbf{Time =}$ $\frac{1}{400}$ oscillations per second

There's your answer! It's $\frac{1}{400}$ oscillations per second:)
