Q 5) A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency.

  • Solution

  • Transcript

Solution 5:

Time period is defined as the time required to complete one oscillation.

Frequency is defined as the number of oscillations per unit time.

Time = 4 sec.

Time Period = (Time taken) / (Number of Oscillations)

Time Period = (4/40) = 0.1 sec.

Frequency = (Number of Oscillations)/ (Time taken)Frequency = (40/4) =10Hz.

"Hello guys welcome to another session of Lido no, we are going to discuss the question number 5 which is all about a pendulum oscillates 40 times in 4 seconds find it's time period and frequency. no first no Force we have to calculate the time period is all about the amount of Parcels Express calculating the time period in Walsall Slade Now we have to divide 4 by 40. Is 0.01 x 0.01? 0.1 seconds and now we are going to find out the Frequency 40 / 4. we should be equal to Den Hegarty so no, thank you guys for watching the fortune the video. Please do like share subscribe and comment in the comment section below if you have any further queries and thank you."
