Question

a pendulum oscillates 10 time in 14 seconds find its time period and frequency​

Answer 1

Time period= Time\no. of oscillation

= 14sec\10= 1.4

frequency= 10\14= 7.142

Answer 2

Time period of pendulum is 1.4 and frequency is 0.714 Hz

• The formula for period (T) is = Time\no. of oscillation

• The formula of frequency as the reciprocal of the period: f = 1/T

• Time period(T)= Time\no. of oscillation = 14 sec\10= 1.4

• Frequency= 1/T= 1/1.4= 0.714 Hz
