just i want to see how we can solve problem # 57 because i didn't see it here so could please show me step by step which is in page503 from fundamentals of physics 8th by halliday,resnick,walker and the question is in fig 18-44a two identical rectangularrods of metal are welded end to end with a temperature of T1=0c on the left side and a temperature of T2 = 100C onthe right side.In 2.0 min . 10J is conducted at a constant ratefrom the right side to the left .How much time would br required toconduct 10 J if the rods were welded side to side as fig18-44b just i want to see how we can solve problem # 57 because i didn't see it here so could please show me step by step which is in page503 from fundamentals of physics 8th by halliday,resnick,walker and the question is in fig 18-44a two identical rectangularrods of metal are welded end to end with a temperature of T1=0c on the left side and a temperature of T2 = 100C onthe right side.In 2.0 min . 10J is conducted at a constant ratefrom the right side to the left .How much time would br required toconduct 10 J if the rods were welded side to side as fig18-44bExplanation / Answer
from the theory we use theequation
Pcond = k A T / L
A / L
Pcond,b = (Ab La/ Aa Lb) Pcond,a
= 4 Pcond,a
