One end of a 0.23-m copper rod with across-sectional area of 1.10 10-4 m2 is driven into thecenter of a sphere of ice at 0° C (radius = 0.14 m). The portion of the rod that is embedded inthe ice is also at 0° C. The rod is horizontal and its otherend is fastened to a wall in a room. The rod and the room are keptat a constant temperature of 26° C.The emissivity of the ice is 0.90. What is the ratio of the heatper second gained by the sphere through conduction to the net heatper second gained by the ice due to radiation? Neglect any heatgained through the sides of the rod.
