Answer:3x + 7y = 63
Explanation:The equation of PQ is
y = -(3/7)x + b
To find b, note that the line passes through the point (7,6). Therefore
6 = -(3/7)*7 + b
6 = -3 + b
b = 9
The equation of PQ is
y = - (3/7)x + 9
or
7y = -3x + 63
3x + 7y = 63
The average temperature of Earth given the solar irradiance is 238.4K.
<h3>How to calculate the temperature?</h3>
The following can be deduced from the information:
Let Earth's albedo =α =0.33
Radius of sun ( Rs) =6.955×10⁵
Value of Boltzmann constant= 5.67×10-⁸
L= 1350
T = average temperature
L= 4σ (Te)⁴ / (1-α)
1 - 0.33 = 4 × 5.67×10-⁸×(T)⁴ / 1350
0.67 × 1350 = 0.0000002268*(T)⁴
(T)⁴ = 3230357142.9
T = 238.4 k
In conclusion, the temperature is 238.4K.
<u>Complete question:</u>
Calculate the average temperature of Earth where the solar irradiance (L) is 1350W/m² and the albedo of Earth is 0.33. Consider Earth to be a perfect black body and the Stefan - Bollzmann constant to be 5.67 × 10^-8 W.
