Answer:Water absorbs different wavelengths of light to different degrees. The longest wavelengths, with the lowest energy, are absorbed first. Red is the first to be absorbed, followed by orange & yellow. The colors disappear underwater in the same order as they appear in the color spectrum. Even water at 5ft depth will have a noticeable loss of red. For this reason, strobes are usually used to add color back to subjects.

Explanation:
We have to find the net charge of a polyatomic ion that contains 49 protons and 50 electrons.
n° of protons = 49 n° of electrons = 50
The charge of each electron is -1 and the charge of each proton is +1.
charge of electron = -1 charge of proton = +1
Finally the net charge will be:
Net charge = n° of electrons * charge of electron + n° of protons * charge of proton
Net charge = 50 * (-1) + 49 * (+1)
Net charge = -1
Answer: C) -1
Answer:
It is the last one.
Explanation:
Water molecules are polar, they have cohesive properties, and water is less dense when it is solid than when it is a liquid, that is why ice floats in liquid water. However, water is a very good solvent, it can dissolve many solids, including sugar, salt, and other hydrophilic substances.
