Charge Q is uniformly distributed along a thin, flexible rod of length L. The rod is then bent into a semicircle. Determine the expression for the electric field E~ at the center of the semicircle.

i believe it is b. what was the cause of the big bang

hope this !

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

the answer is 100. i just did this lesson and got a 100% on it. : )
