Ace. 1.4K answers. 402.8K people helped. the pendulum oscillates 50 times in 6 secs. so time taken to oscillate once= 6/50 secs = 0.12 secs ... frequency = 1/time period= 1/0.12 Hz

Explanation:

Answer 2

Given : A pendulum oscillates 45 times in 5 seconds.

　

To find : What is its time period and frequency?

　

Using formula :

1) Frequency = Number of times the pendulum oscillates/Total number of time taken.

　

2) Time period = Number of oscillation per second/Frequency.

　

Calculations :

→ Frequency = 45/5

→ Frequency = 9 hertz

　

→ Time period = 1/9

→ Time period = 0.1111 seconds

　

Therefore,

1. Frequency = 9 hertz.
2. Time period = 0.1111 seconds.
