What is the net power that a dog with surface area of 0.075 m² radiates if his emissivity is 0.75, his skin temperature is 315 K, and he is in a room with a temperature of 290 K? The Stefan-Boltzmann constant is 5.67 x 10^-8 W/(m²·K⁴). A) 9.0 W B) 6.0 W C) 8.0 W D) 15 W E) 18 W

Quizplus · Accepted Answer

The net power radiated is calculated using the Stefan-Boltzmann law: P = eσA(T₁⁴ - T₂⁴). Substituting the given values: P = 0.75 * 5.67 x 10⁻⁸ * 0.075 * (315⁴ - 290⁴) = 9.0 W.
