The two students are discussing conductor wire student a says that the larger the gauge number of a wire the thicker the wire is student b says that the larger the gauge number of a wire the more current carrying capacity the wire has which of the following statement is correct

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

frequency or wavelenth of em radiation in a vacuum
