InterviewSolution

1.	Each square metre of sun’s surface radiates energy at the rate of 6.27×107 Wm−2. Assuming that Stefan’s law applies to the radiation, the temperature of sun’s surface is (Stefan’s constant σ=5.7×107 Wm−2K−4)
Answer» Each square metre of sun’s surface radiates energy at the rate of $6.27 \times 10^{7} W m^{- 2}$ . Assuming that Stefan’s law applies to the radiation, the temperature of sun’s surface is (Stefan’s constant $σ = 5.7 \times 10^{7} W m^{- 2} K^{- 4}$ )
