Question

If pendulum oscillates 15 times in one mintute.Find its frequency.

Answer 1

⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐

==================================

❄ TERMS & DEFINITIONS ❄


✔ Oscillation : The number of vibrations (one complete to and fro motion) of the bob about its mean position are called oscillations.

✔ Frequency : The number of oscillations made by the bob of a pendulum in one second is called frequency of oscillation.

==================================

❄❄❄❄ SOLUTION ❄❄❄❄

We know, 1 minute = 60 seconds.

Now, it oscillates 15 times in 60 seconds.

In one second it will oscillate (15/60) = 0.25 times.

Thus, frequency = 0.25 Hz.

Answer 2

1 minute = 60 seconds.

Now, it oscillates 15 times in 60 seconds.

In one second it will oscillate (15/60) = 0.25 times.

Thus, frequency = 0.25 Hz.
