Question

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

Answer 1

Answer:

Frequency is defined as the number of oscillations per unit time. Time = 4 sec. Time Period = (4/40) = 0.1 sec. Frequency = (Number of Oscillations)/ (Time taken)Frequency = (40/4) =10Hz.

Time Period,

Time Period,Time period = Time/No. of oscillations in time

Time Period,Time period = Time/No. of oscillations in time→ Time period = 4/40

Time Period,Time period = Time/No. of oscillations in time→ Time period = 4/40→ Time period = 0.1 sec

Time Period,Time period = Time/No. of oscillations in time→ Time period = 4/40→ Time period = 0.1 secFrequency,

Time Period,Time period = Time/No. of oscillations in time→ Time period = 4/40→ Time period = 0.1 secFrequency,Frequency = 1/Time period

Time Period,Time period = Time/No. of oscillations in time→ Time period = 4/40→ Time period = 0.1 secFrequency,Frequency = 1/Time period→ Frequency = 1/0.1

Time Period,Time period = Time/No. of oscillations in time→ Time period = 4/40→ Time period = 0.1 secFrequency,Frequency = 1/Time period→ Frequency = 1/0.1→ Frequency = 10 Hz

Time Period,Time period = Time/No. of oscillations in time→ Time period = 4/40→ Time period = 0.1 secFrequency,Frequency = 1/Time period→ Frequency = 1/0.1→ Frequency = 10 HzHence, the time period is 0.1 sec & frequency is 10 Hz.
