To find the ratio of the rates of cooling of two black bodies at temperatures 400 K and 500 K placed in an evacuated enclosure at 300 K, we can use the Stefan-Boltzmann law. The law states that the power radiated by a black body is proportional to the fourth power of its absolute temperature. ### Step-by-Step Solution: 1. **Identify the Temperatures:** - Let the temperature of black body 1, \( T_1 = 400 \, K \) - Let the temperature of black body 2, \( T_2 = 500 \, K \) - The temperature of the enclosure, \( T_0 = 300 \, K \) ...
