Question

A mass hung from a spring vibrates 15 times in 12 second . calculate the frequency and the period of vibration.

Answer 1

Answer:

answer is 1.25 second

Explanation:

v=15.

time=12

now,

time period of 1revolution =15÷12=1.25

Answer 2

Answer:

frequency= no. of oscillations /time taken=15/12=5/4=1.2hz

so, frequency=1.2hz

time period=1/frequency=1/1.2=10/12=5/6=0.83

so, time period=0.83s.
