A)349 W/m²
B)10.4 W/m²
C)4)9 × 10⁻⁸ W/m²
D)The information cannot be determined with the information given.

Quizplus · Accepted Answer

The rate of radiation emitted by a body can be calculated using the Stefan-Boltzmann Law: $ E = \sigma T^4 $. Substituting the given values, $ E = 5.67 \times 10^{-8} \times (280)^4 $, which equals approximately 349 W/m².
