Intensity of electromagnetic wave is given as
![I = 2[\frac{B_{rms}^2}{2\mu_0}\times c]](https://tex.z-dn.net/?f=I%20%3D%202%5B%5Cfrac%7BB_%7Brms%7D%5E2%7D%7B2%5Cmu_0%7D%5Ctimes%20c%5D)
given that


here we know that


now we have


now we will have


frequency of wave is given as


now the induced EMF is given as



Explanation:
The problem doesn't specify that the units have to be g/mL, so you can calculate the density in kg/L without converting the mass or volume.
Just make sure that either way, you write the units.
Answer:
(A) Their high energy
Explanation:
The higher the energy of the x-ray the more "likely" they will pass through.
The x-ray is electromagnetic energy caused by energy changes in an electron.
X-ray are energetic and have enough energy to break up molecules. That is what reveals the bad or damaged cells in our body.
The last one, the soil will become weak & unable to support plant growth
