The filament of a light bulb is cylindrical with length 1 = 20 mm and radius r = 0.05 mm. The filament is maintained at a temperature T = 5000 K by an electric current. The filament behaves approximately as a black body, emitting radiation isotropically. At night, you observe the light bulb from a distance D = 10 km with the pupil of your eye fully dilated to a radius r = 3 mm. (a) What is the total...

(33%) Problem 3: Warm blooded animals are home otherm that is, they maintain an approximately constant body temperature. (For humans it's about 37°C.) When they are in an environment that is below their optimum temperature, they use energy derived from chemical reactions within their bodies to warm them up One of the ways that animals lose energy to their environment is through radiation. Every object emits electromagnetic radiation that depends on its temperature. For very hot objects like the sun,...
