D)32 degrees Fahrenheit
E)105 degrees Fahrenheit

Question

Quizplus · Accepted Answer

According to the Stefan-Boltzmann law, the rate of energy radiation from a black body is proportional to the fourth power of its absolute temperature. Therefore, the higher the temperature, the greater the rate of energy radiation. Among the given options, 105 degrees Fahrenheit is the highest temperature, so Earth would be radiating energy at the greatest rate or intensity at this temperature.
