Question

If the pendulum completes exactly 12 cycles in 2.0 minutes, what is the frequency of the pendulum?​

Answer 1

Answer:

0.2 Hz

Explanation:

Frequency(in Hertz)= No. of cycles per second

12/( 2× 60) = 12/120 = 0.2 Hertz

Answer 2

Concept:

The pendulum's frequency determines how frequently it swings back and forth over a given length of time.

Given:

No. of cycles= 12

Time taken= 2min

To find:

Frequency of the pendulum

Solution:

Time taken by the pendulum to complete 12cycles= 2min

$1minute= 60seconds\\2minutes = 120sec$

Frequency(Hz) = $\frac{No. of cycles}{time taken}$

$frequency= \frac{12}{120} = 0.10Hz$

The frequency will be 0.10 Hz.
