Two metal rods of equal length-one aluminum, the other stainless steel-are connected in parallel with a temperature

Question:

Two metal rods of equal length-one aluminum, the other stainless steel-are connected in parallel with a temperature of 20.0 °C at one end and 118 °C at the other end. Both rods have a circular cross section with a diameter of 3.50 cm.

(a) Determine the length the rods must have if the combined rate of heat flow through them is to be 27.5 J per second.

(b) If the length of the rods is doubled, by what factor does the rate of heat flow change?
