Question

A pendlum oscillates 90times in 90 seconds find it's time period and frequency. ​

Answer 1

Answer:

frequency = 1

time period = 1

Explanation

total number of complete oscillation = 90

total number of seconds = 90

To take out frequency formula

Frequency = No of vibration / seconds

therefore, frequency = 90 / 90

which is equal to 1

hence, frequency = 1

to take out time period formula

time period = 1 / frequency

therefore , time period = 1 / 1

which is equals to 1

hence, time period = 1
