Answer:
The time interval is
Explanation:
From the question we are told that
The constant acceleration is
The displacement is
According to the second equation of motion we have that
given that the blade started from rest
which is the initial angular velocity is 0
So
=>
substituting values
=>
=>
The correct answer is amplify each other
If they move at the same speed with the same frequency in the the same direction, then they will amplify each other due to constructive interference.

Explanation:
Answer:
The dead spot experienced was due to the effect of sound wave interference
Explanation:
Sound wave interference occurs when wave interact. They can interact constructive manner increasing each other's strength and rising the intensity of the final wave produced.The waves can also interact destructively reducing each other's strength and intensity.In some cases, destructive interaction causes a total cancelling of the waves resulting to places where no sound can be heard at all.This area is the dead spot.
