Two metal rods of equal length-one aluminum, the other stainless steel-are connected in parallel with a temperature of 16.0%u2218C at one end and 126%u2218C at the other end. Both rods have a circular cross section with a diameter of 5.00cm

Part A
Determine the length the rods must have if the combined rate of heat flow through them is to be 27.5J per second.
Express your answer using two significant figures.

Part B
If the length of the rods is doubled, by what factor does the rate of heat flow change?
Express your answer using three significant figures.
