i dont know the answer of your question correctly
The amount of energy that a wave may transfer to a unit area of a surface each second is measured as the wave's intensity. Watts per square meter is a unit used to express intensity. A sound wave's frequency is equal to its rate of vibration, and its intensity is determined by its amplitude.
<h3>What is the intensity of sound waves affect the frequency?</h3>
The energy of a vibration is quantified in decibels as intensity or loudness (dB). A sound has a high intensity if it is loud.
Therefore, perceive noise as louder the higher the frequency, although frequency does not indicate how loud a sound is.

Answer:
layers of cotton lining the interior
Explanation:
Answer: Option A: 22.5 m
Explanation:
A stone is dropped from a tower. The initial velocity of the stone, u = 0.
Height of the tower, y = 100 m
Let the depth of the well be d.
Time taken of the drop of the stone, t = 5 s
The stone falls under acceleration due to gravity g = 9.81 m/s²
We will use second equation of motion:
s = u t + 0.5 g t²
⇒100 m + d = 0 + 0.5 × 9.81 m/s²× (5.00 s)²
⇒d = (122.6 - 100) m = 22.6 m ≅ 22.5 m
Thus, the correct option is A. The depth of the well is 22.5 m.
