The wire is made up of atoms with molecular mass 78 g/mol. What is the drift speed of the electrons when there is a voltage drop of 35.4 V across the wire? Assume there is one conduction electron per atom. The fundamental charge is 1.602 × 10−19 C. Answer in units of m/s.

no

sodium is solid at rt

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

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
