Question

class 9.
I. Find the time period of oscellations of a body vibrates 150 times in a ​

Answer 1

Explanation:

F = no of oscellation /time taken

F = 150/60

F = 2.5

T = 1/f

T = 1/2.5

T = 0.4s

I hope you get the answer....

Answer 2

F=no of oscillation/ time taken
F=150/60
F=2.5
T=1/f
T=1/2.5
T=0.4s
