9) A cup of coffee is in an insulated cup 1/2 cm thick in the shape of a cube 10 cm on a side. The temperature of the coffee is 95° C and the surrounding temperature is 21°C. Find the ratio of the heat loss due to conduction to the heat loss due to radiation. (Assume an emissivity of 1 and a thermal conductivity of 2 x 10-4 cal/sxcmx Cº). a. 17 b. 9 c. 2 d. 26
