<span>The atom becomes positively charged.

When you add electrons to a neutral atom, it is no longer a neutral atom, it has a negative change and is an anion. When you take away electrons from a neutral atom, it is no longer a neutral atom- it becomes a positive atom, and is a cation.</span>

dybincka [34]

   Work = (force) x (distance)

The work he did: Work = (700 N) x (4m) = 2,800 joules

The rate at which
he did it (power):    Work/time = 2,800 joules/2 sec

      = 1,400 joules/sec

      = 1,400 watts

= 1.877... horsepower (rounded)

Energy is inversely proportional to the wavelength of a wave. Which would have the GREATEST energy? A wave with a

Ivan

Answer:

A 5

Explanation:

The wave with the least amount of wavelength will have the greatest amount of energy.

Wavelength and energy shares an inverse relationship;

E = h f = $\frac{hc}{wavelength}$

From this equation, we see that the higher the energy of a wave, the lesser its wavelength.

Choice A from the options has the least wavelength.
Wavelength is the distance between two successive crests of a wave.

This is why we see that in the electromagnetic spectrum, radio waves have the least energy because they have the longest wavelength.
