Question

Solar constant on earth is 1.36 × 103 W m–2, If Mars is at a distance of 1.52 AU from the sun, calculate the solar constant on Mars applying Stefans Law

Answer 1

Hello friend,

¶ Solar constant -
It's the power of solar electromagnetic radiation per units area.
Ks = σAT^4 / πd^2
Ks ∝ 1/d^2

◆ Answer-
Km = 588.64 W/m^2

◆ Explanation-
# Given-
de = 1 AU
dm = 1.52 AU
Ke = 1.36×10^3 W/m^2

# Solution-
From the formula we can write,
Ke/Km = (dm/de)
Km = Ke (de/dm)^2
Km = 1.36×10^3 × (1/1.52)^2
Km = 588.64 W/m^2

Therefore, solar constant of mars is 588.64 W/m^2.

Hope it helps...

Answer 2
