One end of a plastic pipe is capped and the other end is open. the pipe stands on the capped end in a magnetic field of 0.030 t that makes an angle of 10° with the vertical. the pipe has an inside diameter of 5 cm. what is the flux through the plastic of the pipe?

magnetic flux = 0.579 × Weber

Explanation:

given data

magnetic field B = 0.030 T

angle ∅ = 10°

diameter d = 5 cm

to find out

flux through the plastic of the pipe

solution

we get here magnetic flux that is express as

magnetic flux = magnetic field × Area × cos∅    ..............1

put here value we get

magnetic flux = 0.030 × × cos10

magnetic flux = 0.030 × × cos10

magnetic flux = 0.030 × 1.9634 × × 0.984

magnetic flux = 0.579 × Weber

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
