Expert Answer
heat produced by the wire is H= i2Rt
here "i" is the current in the wire , "R" is the resistance of the wire and "t" is the time for which current is flowing in the wire
now resistance is proportnal to the length of the wire
so heat produced by the wire 1 is H1=i2Rt
and heat produced by the wire 2 is H2=i22Rt
then (H1/H2)=1:2
