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 the 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 - Boltzmann constant to be 5.67 × 10^-8 W.

Can humans survive without plans?explain your answer
Mnenie [13.5K]

Answer:

Well.....

Explanation:

  There is a possible chance that humans would survive with out plans but they could also not survive without plans. I chose to be on the side where humans wouldn't survive without plans. The reason that they would not be able to survive would be because if they had no plans and most people rely on the plans for surviving that why I think they wouldn't survive.

     But on the other hand, if they knew surviving skills or at least had a back up plan if they lost their plans, they would definitely survive. I hope this is the answer your looking for, This knowledge came from my head.
