Explain how the tilt of the earths axis and the revolution of the earth cause the day and night to change at different times of the year

well to explain it well:

Explanation:

since the earth spins or rotates on it's axis it causes the people from all over the world to experience day and night, and because of this there is 2 annual times of light and dark that are separated by the sunrise and the sunset.

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
