Question

The time period of a pendulum is 0.5 s. No of oscillations of the pendulum is 20. Find the time taken to complete 20 oscillations (with explanation pls)

Answer 1

• Time period=0.5s
• No if oscillations=20

$\\ \sf\longmapsto Time\:period=\dfrac{Time\:taken}{No\:of\; oscillations}$

$\\ \sf\longmapsto Time\:taken=No\:of\: oscillations (Time\: period)$

$\\ \sf\longmapsto Time\:taken=20(0.5)$

$\\ \sf\longmapsto Time\:taken=10s$

Answer 2

Given :

• Time period = 0.5s
• Number of oscillations = 20

What To Find :

• Time taken to complete 20 oscillations.

Formula Using :

$\begin{gathered} {\underline{\boxed{ \rm {\red{Time \: period \: = \: \frac{Time \: \: taken}{Number \: of \: oscillations} }}}}}\end{gathered}$

$\begin{gathered} {\underline{\boxed{ \rm {\purple{Time \: taken \: = \: Number \: of \: oscillations \: (Time \: period)}}}}}\end{gathered}$

Solution :

$\large \rightarrow \: {\rm {{{\color{orange}{Time \: taken \: = \: 20 (0.5)}}}}}$

$\large \rightarrow \: {\rm {{{\color{orange}{Time \: taken \: = \: 10s}}}}}$
