False, the radiation from food and medical procedures have very little consequences. The radiation from a nuclear power plant can kill people which makes it a very large problem if not contained properly.

Wavelength is the distance of one frequency wave peak to the other and
is most commonly associated with the electromagnetic spectrum.[1]
Calculating wavelength is dependent upon the information you are given.
If you know the speed and frequency of the wave, you can use the basic
formula for wavelength. If you want to determine the wavelength of light
given the specific energy of a photon, you would use the energy
equation. Calculating wavelength is easy as long as you know the correct
equation.
According to Raoult's low:
We will use this formula: Vp(Solution) = mole fraction of solvent * Vp(solvent)
∴ mole fraction of solvent = Vp(Solu) / Vp (Solv)
when we have Vp(solu) = 25.7 torr & Vp(solv) = 31.8 torr
So by substitution:
∴ mole fraction of solvent = 25.7 / 31.8 =0.808
when we assume the moles of solute NaCl = X
and according to the mole fraction of solvent formula:
mole fraction of solvent = moles of solvent / (moles of solvent + moles of solute)
by substitute:
∴ 0.808 = 0.115 / (0.115 + X)
So X (the no.of moles of NaCl) = 0.027 m
Answer: When you burned the skewer tip coated with copper sulfate the green light is emitted
Explanation:
when the copper is burned it makes a green light
Once the water evaporates, you will start to see the minerals that were present in the water before it changed state. If the water was from the ocean, you will see salt crystals in the evaporated water. If the water was fresh, you may see other minerals typically found in fresh water.
