Answer:
D) ¼ as large
Explanation:
The magnitude of the electric force between two charges is
where
k is the Coulomb's constant
q1 and q2 are the magnitudes of the two charges
r is the separation between them
From the formula we see that the magnitude of the force is inversely proportional to the square of the distance.
In this problem, the distance is doubled:
So the new force will be
So the force will decrease to 1/4 of its original value.
Answer:
Amount of Protons
Explanation:
If this is what you are asking for, the atomic number is equal to the amount of protons, while the atomic mass is equal to the amount of protons *plus* neutrons.
Light is refracted when it crosses the interface from air into glass in which it moves more slowly. Since the light speed changes at the interface, the wavelength of the light must change, also. The wavelength decreases as the light enters the medium and the light wave changes direction.

Answer:
25mph
Explanation:
you do distance divided by time. 200/8=25
