Answer:
Therefore the capacitance of the capacitor is 2.38 * 10⁻⁵F
Explanation:
We apply the concepts related to Power and energy stored in a capacitor.
By definition we know that power is represented as
Where,
E= Energy
t = time
to find the Energy we have,
With the energy found we can know calculate the Capacitance in a capacitor through the energy for capacitor equation, that is
Therefore the capacitance of the capacitor is 2.38 * 10⁻⁵F
Answer:
<em>From the image, the force as shown in option A will exert the biggest torque on the cylinder about its central axes.</em>
Explanation:
The image is shown below.
Torque is the product of a force about the center of rotation of a body, and the radius through which the force acts. For a given case such as this, in which the cylinders are identical, and the forces are of equal magnitude, the torque at the maximum radius away from the center will exert the maximum torque. Also, the direction of the force also matters. To generate the maximum torque, the force must be directed tangentially away from the circle formed by the radius through which the force acts away from the center. Option A satisfies both condition and hence will exert the most torque on the cylinder.
