Answer:
Power output =
Explanation:
Given:
Mass of the elevator is,
Height to which it is raised is,
Acceleration due to gravity is,
Time taken by the motor to raise the elevator is,
Now, work done on the elevator by the motor is equal to the increase in the gravitational potential energy of the elevator.
Increase in gravitational potential energy is given as:
Therefore, work done by motor is,
Now, we know that, power is work done in unit time. So, power output is given as:
Therefore, the power output of the first motor is
It is a type capacitor is in which two metal plates arranged in such a way so that they are connected in parallel . The potential energy is stored in the capacitor will be 2.7×10⁻⁵.
<h3>What is parallel plate capacitor ?</h3>It is an type capacitor is an in which two metal plates arranged in such a way so that they are connected in parallel and have some distance between them.
A dielectric medium is a must in between these plates. helps to stop the flow of electric current through it due to its non-conductive nature .
The given data in the problem is;
Q is the charge= 1.5 µC
V is the change in voltage across the plates is = 36 V.
U is the potential energy=?
The formula for the potential energy is given by;
Hence the potential energy is stored in the capacitor will be 2.7×10⁻⁵.
