Problem 19.72 - Enhanced - with Hints and Feedback A satellite to reflect radar is a 4.0-m-diameter, 2.0-mm-thick spherical copper shell. While orbiting the earth, the satellite absorbs sunlight and is warmed to 50 C. When it passes into the earth's shadow, the satellite radiates energy to deep space. The temperature of deep space is actually 3 K, as a result of the Big Bang 14 billion years ago, but it is so much colder than the satellite that you can assume a deep-space temperature of 0 K. Part A If the satellite's emissivity is 0.75, to what temperature, in C, will it drop during the 55 minutes it takes to move through the earth's shadow? Express your answer in degrees Celsius. You did not open hints for this part. ANSWER: If = . C
