Please help ^^ A set of charged plates is
separated by 8.08*10^-5 m. When
2.24*10^_9 C of charge is placed
on the plates, it creates a potential
difference of 855 V. What is the
area of the plates?

this is poiselle's equation from fluid mechanic in physics. mech eng

measure their densities same density, same sub

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
