Rods of copper, brass, and steel are welded together to form a Y-shaped figure. The cross-sectional area of each rod is 2.00 cm^2. The free end of the copper rod is maintained at 100 deg C and the free ends of the brass and steel rods at 0.0 deg C. Assume there is no heat loss from the surfaces of the rods. The lengths of the rods are: copper, 13.0 cm; brass, 18.0 cm; steel, 24.0 cm.  (a) What is the temperature of the junction point? (b) What is the heat current in each of the three rods? (c)What is the Sun's total power output?
