Answer:
Displacement current flows in the dielectric material(insulated region)
Explanation:
Firstly a capacitor stores charge when a capacitor is charging (or discharging), current flows in the circuit. Also, there is no charge transfer in the dielectric material in the capacitor which is contradictory to the flow of current. Hence, displacement current is the current in the insulated region due to the changing electric flux.
Input energy is: 200 joule
Output energy is: 100 joule
100/200*100=%50 efficiency
B. Elastic potential to kinetic energy
The elastic potential energy in the slingshot will be transferred to the stone as kinetic energy as the stone is launched.
Answer:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. ... In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A.
Answer:
Therefore
Number of turns in the solenoid is 19407.
Explanation:
Given:
Strength magnetic field at its center,
B = 7.5 T
length of solenoid = l = 0.26 m
Current, I = 80 A
To Find:
Turn = N = ?
Solution:
If N is the number of turns in the length, the total current through the rectangle is NI. Therefore, Ampere’s law applied to this path gives
Therefore,
Where,
B = Strength of magnetic field
l = Length of solenoid
N = Number of turns
I = Current
Substituting the values we get
Therefore
Number of turns in the solenoid is 19407.
