Question

a pendulum oscillates 40 times in 4 seconds find the time period and frequency​

Answer 1

Answer:

0.1s^-1

Explanation:

time period equals to total number of oscillations divided by total time

frequency is equals to 1 divided by time period

Answer 2

Time Period,

Time period = Time/No. of oscillations in time

→ Time period = 4/40

→ Time period = 0.1 sec

Frequency,

Frequency = 1/Time period

→ Frequency = 1/0.1

→ Frequency = 10 Hz

• Hence, the time period is 0.1 sec & frequency is 10 Hz.
