Answer:
Explanation:
(Assuming the cell in the circuit has 0 internal resistance)
Ohm's Law is given as:
Voltage is Current multiplied by Resistance.
We can rearrange this formula to give us:
Now we can plug in our values

Answer:
Explanation:
a)At the base of the surface the Electric flux is easy to find, because the Electric Field is constant in magnitude and perpendicular to the flat surface:
The Flux is negative because the Electric field goes into the surface
b) The Gaussian surface in form of a hemisphere encloses no net charge. The Gauss law says that the Flux of the electric field is proportional to the net charge enclosed. At this case, the charge is zero, then the total Flux is zero too.
Then:
The Flux is positif because the Electric field goes out of the surface.
Explanation:
We assume kinetic and potential energy changes are negligible and there is no work interactions.
