Answer:

The heat equation can be written as. ∂ u ∂ t = α ∇ 2 u. where u(x, y, t) is the temperature field that varies in space and time, and α is the thermal diffusivity constant.

Answer:

In mathematics and physics, the heat equation is a certain partial differential equation. ... The theory of the heat equation was first developed by Joseph Fourier in 1822 for the purpose of modeling how a quantity such as heat diffuses through a given region

1) Using the simple earth energy model we developed in class, calculate the average
andriy [413]

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.
