Answer: The amount of energy transferred to each eardrum in one second is .
Explanation:
Given: Intensity = 0.10
Now, at 30.0 m the intensity will be calculated as follows.
This means that the intensity is 900 times less assuming that the wave is spherical.
Hence, the new intensity is calculated as follows.
The area of ear drum is expressed as follows.
Formula used to calculate energy is as follows.
where,
P = power or energy
I = intensity
a = area
Substitute the values into above formula as follows.
Thus, we can conclude that amount of energy transferred to each eardrum in one second is .
