2. A circular lake 1.0 km in diameter is 10 m deep. Solar energy is incident on the lake's surface at an average rate of 1160 W/m². The lake absorbs all this energy and does not exchange heat with its surroundings. How long will it take for the temperature of the water to increase by 0.2°C? The specific heat of water is 4180 J/(kg °C), and its density is 10³ kg/m². A. 9.3 h. B. 2.0 h. Q=MAT C. 4.0 h. 1.0 km D. 7.0 h. E. 11.0 h. 10 m
