Determine the energy, in J, of a photon with a
wavelength of 349 nm. (h =
6.626 x 10-34 J·s and c =
3.00 x 108 m/s)

we need the questions , i may then you.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

diaria maybe go see a doctor about that
