Answer:-

\red{\bigstar} Time Period \large\leadsto\boxed{\rm\pink{0.6 \: seconds}}

\red{\bigstar} Frequency \large\leadsto\boxed{\rm\pink{1.67 \: Hz}}

Given:-

Pendulum oscillates 50 times in 30 seconds

To Find:-

  • Time Period
  • Frequency

Solution:-

Frequency:-

We know,

\pink{\bigstar} \large\underline{\boxed{\orange{F = \dfrac{No. \: of \: oscillations}{Total \: time \: taken}}}}

Substituting in the Formula:-

\sf F = \dfrac{50}{30}

\sf F = 1.666666667

\bf\red{F = 1.67 \: Hz}

Time Period:-

We know,

\pink{\bigstar} \large\underline{\boxed{\orange{T = \dfrac{1}{f}}}}

where,

  • T = time period
  • f = frequency

Substituting in the Formula:-

\sf T = \dfrac{1}{1.67}

\sf T = 0.598802395

\bf\red{T = 0.6 \: sec.}

Therefore, the time period is 0.6 seconds and frequency is 1.67 Hz.
