Pendulum complete 25 o oscillation in in 45 second how many oscillation it complete
Answers
Answer:
For 15 oscillation it takes 30 sec
For one oscillation Tme period = 30/15 = 2sec
Frequency = 1/ Time period
=1/2=0.5 Hz
Explanation:
Time period is the time needed to complete one oscillation. That means,
Time Period = time/ no. of oscillations
= 30 seconds/ 15 oscillations
= 2 seconds per oscillation
Time Period = 2 s
2.Frequency is the number of oscillations per second. That means,
Frequency = no. of oscillations/ time
= 15 oscillations / 30 seconds
= 0.5 oscillations per second
Frequency = 0.5 Hz (hertz)
From above answers we can get below relationship,
Frequency = 1/Time Period
For 15 oscillation it takes 30 sec
For one oscillation Tme period = 30/15 = 2sec
Frequency = 1/ Time period
Frequency = (1/2)Sec^-1 = 0.5 Sec^-1
A simple pendulum makes 10 oscillations in 20 seconds.
time period=?
frequency=?
A pendulum makes 10 oscillations in 20 seconds.
So it makes 1 oscillation in 20/10sec.=2sec
Time period=2 sec
Frequency=1/T=1/2=0.5 Hz
∴Time period and frequency of its oscillation are 2sec and 0.5 hertz .
