Suppose the base of a 40cm2 pan is made of two different materials each with thickness equal to 0.20 cm. The top side is made of steel [k=0.46W/(cm*K)] and the bottom side is made of copper [k=4.01W/(cm*K)], as shown below.

a) Calculate the temperature of the bottom surface.

b) What is the thermal current through
