The ranges of frequency are:
UVA: ![[7.50-9.38]\cdot 10^{14} Hz](https://tex.z-dn.net/?f=%5B7.50-9.38%5D%5Ccdot%2010%5E%7B14%7D%20Hz)
UVB: ![[9.38-10.71]\cdot 10^{14} Hz](https://tex.z-dn.net/?f=%5B9.38-10.71%5D%5Ccdot%2010%5E%7B14%7D%20Hz)
Explanation:
The relationship between frequency and wavelength for an electromagnetic wave is the following:
where
f is the frequency
is the speed of light
is the wavelength
For the UVA, the range of wavelength is 320 nm - 400 nm, so
So the corresponding frequencies are
For the UVB, the range of wavelength is 280 nm - 320 nm, so
So the corresponding frequencies are
So the ranges of frequency are:
UVA:
UVB:

T = 3.5 secs
Velocity (v) = g * t = 10 m/s^2 * 3.5 sec = 35 m/s
Explanation:
Distance and amount of charge are factors that determine which of the
following quantities?
D. All of the above
An electric current<span> is a </span>flow<span> of </span>electric<span> charge. In </span>electric<span> circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma).</span>
The correct answer would be c
