Explain how magnetic flux can be zero when the magnetic field is not zero.

The magnetic flux is generated when there is change in the magnitude of the magnetic field as well as its direction. ... If the magnetic field is parallel to the place of the area exposed then the magnetic flux generated is zero when the magnetic field is not zero.

small = small current large mag large current

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
