I don't understand this question
<em>iron or steel is only magnetized when current is passed through it...
ship is magnetized because <u></u>it has a superstructure,, during welding of ship enormous amount of current is passed through it and also it goes on and on path through the whole structure which aggregates the current up to thousands of amperes ,,,
as a result this current re aline all the molecules because of which they become a little magnetic and make the entire steel ship magnetic :)</em>
The additional charge transferred to the capacitors by the battery is 60 μC.
The increase in the total charge stored on the capacitors is 60 μC.
<u>Explanation</u>:
C = εоA / d
If the separation is halved, then the capacitance will be doubled and according to the equation q = CV, the charge will be doubled too.
- Initial charge of the capacitor is:
q = CV
= (6e - 6)
(10)
= 60 μC
Final charge of the capacitor:
q = (2C)V
= (2
6e - 6)
(10)
= 120 μC
additional charge transmitted is:
q' = 120 - 60
= 60 μC
= (C1 + C2) V
= (6 + 6)
(10)
= 120 μF
final total charge:
= (C1 + C2) V
= (2
6 + 6)
(10)
= 180 μF
Increase in the charge:
q' = 180 - 120
= 60 μC
Parallel to the velocity city is zero
