In physics lab, you hang a wire perpendicular to the magnetic field created by a horseshoe magnet. You observe that the wire moves downward when you allow
current to flow throligh it. What happens when you reverse the direction of current?

a) The wire moves toward the South pole of the magnet.

b) The wire moves further downward.

c) The wire moves upward.

d) The wire moves toward the North pole of the magnet.

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

just copy what u wrote and paste and search in google
