Answer:
Time interval for which magnetic field reduced to ZERO is given as
Explanation:
As we know that the flux linked with one coil is given as
now total flux of all coils is given as
now let say the flux is reduced to ZERO after time "t"
so as per Faraday's law EMF induced in the coil is given as
now the current in the coil is given as
so the time interval is given as
Answer:
Explanation:
Kinetic energy involves motion so something that is not moving has zero kinetic energy.
Potential energy does not involve motion and is based on position in a field like gravity and magnetic.
Answer:
400 m
Explanation:
The swimmer swims 50 meters to one end of the pool but has to swim back therefore you double 50 which would be 100 meters. Then you have to multiply 100 by 4 since the swimmer did it 4 times.
