A copper wire of length 4.00 cm and radius 4.00 mm has a potential difference of 4.00 nV across the ends of the wire. Calculate the amount of charge in microCoulombs) drifting through the cross section in 4.00 ms. Assume the resistivity of copper is 1.70 x 10-8 Ohm-meters.

1. 101.88
2. 1.18
3. 0.59
4. 41.40
5. 66.35 [10 points]

The amount of charge in microCoulombs is 1.18 ( Q = 1.18µC).

The correct option is 2

Explanation: Please see the attachments below

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
