-- 'Ca' (Calcium) is an element.
-- The proton has a positive charge.
-- Nuclear fusion results in the synthesis of atoms of new elements.
-- H₂O (water) is a chemical compound.
-- Nuclear fission is a decay of the nucleus.
-- The atomic number of an element is the number of protons
in each atom of it.
-- I suppose you're using the Greek letter <span>η ('eta', not 'nu')
to represent the neutron.
-- I suppose you're using ' e ' to represent the electron.

Because the top layer of a pool will be warmer than the bottom layer, that why filtration is important to cycle the water evenly.
Well, it would do you well to number the answers, but Electric input, Mechanical output, and Magnetic forces turn the loop.
You'll have to trust me on this one.
15) Use v^2=u^2+2as
So (65)^2=(0)^2+2(2.50)(s)
Then just solve that^.
Answer:
The refractive index of a medium is dependent (to some extent) upon the frequency of light passing through, with the highest frequencies having the highest values of n. It also changes the wave speed, frequency, and wavelength.. Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases
