Question: Two isolated systems with different temperatures are connected via a long metal rod. The metal rod conducts heat between the two systems at a rate

Two isolated systems with different temperatures are connected via a long metal rod. The metal rod conducts heat between the two systems at a rate of 50cals. What will happen to the rate of the heat flow, if the length of the metal rod is elongated 2 times the original distance as well as increasing the crosssectional diameter by 2 times?
No need to write the unit. Please write the answer in one decimal place. (e.g.1.234 should be written as 1.2).
