Question

A pendulum oscillates 40 times in 5 seconds. Find its frequency ?

Answer 1

• Time period =
• Time period = Number of oscillations in time t
• Time period = Number of oscillations in time tt
• Time period = Number of oscillations in time tt
• Time period = Number of oscillations in time tt =
• Time period = Number of oscillations in time tt = 40
• Time period = Number of oscillations in time tt = 404
• Time period = Number of oscillations in time tt = 404
• Time period = Number of oscillations in time tt = 404 =0.1 s
• Time period = Number of oscillations in time tt = 404 =0.1 sFrequency =
• Time period = Number of oscillations in time tt = 404 =0.1 sFrequency = Time period
• Time period = Number of oscillations in time tt = 404 =0.1 sFrequency = Time period1
• Time period = Number of oscillations in time tt = 404 =0.1 sFrequency = Time period1
• Time period = Number of oscillations in time tt = 404 =0.1 sFrequency = Time period1 =10 Hz
