2 thing it is used for are commonly like wind turbines and water turbines.
It would be D I believe! Depending on the angle of the mirror and distance positioned!
We can solve the problem by using Ohm's law, which states that an Ohmic conductor the following relationship holds:

where

is the potential difference applied to the resistor
I is the current flowing through it
R is the resistance
In our problem, I=4.00 A and

, so the potential difference is
It is the branch of science, in which we study different phenomena of atmosphere including climate and weather.
