Question

An object completes 1500 vibrations in 50 seconds. Calculate the frequency and time

period of a vibration​

Answer 1

Answer:

vibrations in 50 seconds= 1500

vibrations in 1 second= 1500/50= 30

therefore,

frequency =f= 30 vib/sec

and,

time period = T= 1/f= 1/30= 0.033 sec.

Explanation:

• In question, we are given that 1500 vibrations are performed in 50 seconds.
• We have to find out the number of vibrations in 1 second to find out the frequency .
• So we use Unitary method to find the frequency and divide 1500 with 50 to get our answer that is 30 Hz .
• As frequency and time period are inverse of each other , so we inverse the value of frequency to get our answer that is 0.033 sec.
