Answer:
Required wavelength of light is 85.6 nm.
Explanation:
E = h×ν = ![\frac{hc}{\lambda}](https://tex.z-dn.net/?f=%5Cfrac%7Bhc%7D%7B%5Clambda%7D)
E = Energy in J
ν = frequency (Hz s-1)
λ = wavelength in m
Planck constant h = J s
c = speed of light = m s-1
2.32 aJ = J
E = h×ν
![\lambda = \frac{2.998\times10^{8}}{3.50\times10^{15}}=8.56\times10^{-8} m = 85.6 nm](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7B2.998%5Ctimes10%5E%7B8%7D%7D%7B3.50%5Ctimes10%5E%7B15%7D%7D%3D8.56%5Ctimes10%5E%7B-8%7D%20m%20%3D%2085.6%20nm)
Answer:coming together and moving apart
Explanation:
thay do both
That’s false, protons have a positive charge, electron have a negative charge, and neutrons are just neutral. All of them have different charges.
You picked the correct answer. Its amorphous solid. Good luck on the rest!
Answer:
The force is <u>1</u><u>.</u><u>5</u><u>N</u>
Explanation:
