Answer:
50 dB.
Explanation:
given,
Amplification needed by the woman,I= 1 x 10⁵ I₀
where as I₀ is the threshold frequency
overall hearing loss of the woman= ?
Using the equation of sound intensity level
The overall hearing loss of woman is equal to 50 dB.
Answer:
(C) Decreases by factor of 3
Explanation:
Centripetal acceleration is given by
where <em>v</em> is the linear velocity and <em>r</em> is the radius of the curve.
Let the centripetal acceleration on the curve of radius <em>R</em> be .
Then
Let the centripetal acceleration on the curve of radius 3<em>R</em> be .
Then
Here, we see that the acceleration decreases by a factor of 3.
