Apendulum makes 36 vibrations in 60 seconds, what is its: period? and frequency

 Period = 1.67 seconds

 Frequency = 0.6 Hz

Explanation:

  Number of vibrations in 60 seconds = 36

  Frequency is defined as vibrations per second.

  So, Frequency = 36/60 = 0.6 Hz

  Time period is defines as time taken for 1 vibration,

 So, Time period = 60/36 = 1.67 seconds.
