2. Fruit is impeded from ripening when reaches high temperatures (>32°C). Farmer Joe is worried that Princeton's summer heat wave will affect the ripening of his ground cherries. The spherical fruit (1 cm in diameter) is surrounded by a spherical papery husk (husk = 0.3 W/m K) with an inner diameter of 2 cm and an outer diameter of 2.1 cm. The air in between the fruit and the husk is stagnant (air = 0.03 W/m K). On a calm day in July, the Princeton air (outside of the husk) is very warm, with a temperature of ~38°C and a heat transfer coefficient of hprinceton,calm = 10 W/m².K. (a) Sketch the system labeling all temperatures, dimensions, and proportionality constants.
