Answer:
0.0018 W/m²
Explanation:
Power and intensity are related as:
P= 20.0 W (given)
r = 30.0 m (given)
Intensity in decibels:
We will make the comparison between each of the sizes against the known wavelengths.
In the case of the <em>hydrogen atom</em>, we know that this is equivalent to m on average, which corresponds to the wavelength corresponding to X-rays.
In the case of the <em>Virus</em> we know that it is oscillating in a size of 30nm to 200 nm, so the size of the virus is equivalent to the range of the wavelength of an ultraviolet ray.
In the case of <em>height</em>, it fluctuates in a person around to
m, which falls to the wavelength of a radio wave.
