It says Two metal rods of equal length-one aluminum, the otherstainless steel-are connected in parallel with a temperature of26.0 ∘C∘C at one end and 110 ∘C∘C at the other end. Both rods havea circular cross section with a diameter of 4.50 cm
PT.A
Determine the length the rods must have if the combined rate ofheat flow through them is to be 40.0 JJ per second.
Express your answer using two significant figures.
I wrote 0.51... it was wrong... Pt B says If the length ofthe rods is doubled, by what factor does the rate of heat flowchange? I wrote 4... it did not work.
