There 2 forces acting in oppisite derections on a object
Answer:6.74 s
Explanation:
Given
diameter=6 mm
d=0.01m
L=204 m
v=17 m/s
from rayleigh's critterion for resolution
When object absorbs energy then due to this energy it will have increase in it natural frequency
This increase in natural frequency will lead it to the increase in the amplitude of the object
Now when natural frequency of the object will match with the frequency of the wave that is absorbed by the object then this phenomenon is known as Resonance.
In resonance the amplitude of object will rise high and it will reach to its maximum limit.
so at condition
then in this condition it is known as resonance
