4. A woman finds the front windshield of her car covered with ice at -12°C. The ice has a thickness of 1.0 cm, and the windshield has an area of 1.25 m². The windshield is directly exposed to the Sun. If the average solar power falling on the windshield is is 250 Watts, how long (in hours) will it take to melt all the ice? (The density of ice is 920 kg/m³ and the latent heat of fusion of water is 334 kJ/kg, specific heat of ice is 2.00 kJ/kg.K)

39. The concrete wall of a building is 0.10 m thick. The temperatureinside the building is 20.0 8C, while the temperature outside is 0.0 8C.Heat is conducted through the wall. When the building is unheated, theinside temperature falls to 0.0 8C, and heat conduction ceases. However,the wall does emit radiant energy when its temperature is 0.0 8C. Theradiant energy emitted per second per square meter at 0.0 8C is the sameas the heat lost per second per square meter due to conduction whenthe temperature inside the building is 20.0 8C. What is the emissivityof the wall?
