Answer :
Answer: B. 186,00 miles per second.
Explanation:
The speed of light in a vacuum is equal to
1 / sqrt(e0 * u0)
where e0 is the electric permittivity of free space, and u0 is the magnetic permeability of free space. So that's where the speed of light comes from.
But where do the permittivity and permeability come from? Actually, nobody knows. They are seemingly arbitrary universal constants.
