Because although they cannot see it, they can see it's influence on objects that can be seen, and it's effects.
Gauss law states that the electric flux through any closed
surface is proportional to the net electric charge inside the surface. This is
expressed mathematically in the form of:
Φ = Q / εo
Where,
Φ = the electric flux = unknown (which we have to find for)
Q = the net electric charge = 5.0 µC = 5 E-6 C
εo = the permittivity of free space = a constant value =
8.85 E-12 C^2 / N m^2
Plugging in the values
into the equation will result in:
Φ = 5 E-6
C / (8.85 E-12 C^2 / N m^2)
Φ = 564,971.75 Wb = <span>5.6 x
10^5 Wb </span>
Answer:
Explanation:
The speed of light through a medium is given by:
where
is the speed of light through vacuum
n is the index of refraction of the material
In this case, diamond has a refractive index of n = 2.4, so the speed of light in diamond is
