Ocean waves depend on wind for energy. The wind blows on the surface of the water, the energy is transferred from the wind to the waves through vibration of particles. Energy transfers from potential energy to kinetic energy

3) When the temperature of a blackbody increases from 900 K to 2300 K, by what factor does the total power of the electromagneti

LekaFEV [45]

Answer:

The electromagnetic radiation per-unit- area increase by 42.65 times.

Explanation:

The radiation per-unit- area (P) is directly proportional to the fourth power of the temperature. Thus,

P ∝ T⁴

For, when the temperature is raised from T₀ to T₁ , the radiation per-unit- area is related to as:

$\frac {P_1}{P_0}=\frac {T_1^4}{T_0^4}$

T₀ = 900 K

T₁ = 2300 K

$\frac {P_1}{P_0}=\frac {2300^4}{900^4}$

So,

<u>The electromagnetic radiation per-unit- area increase by 42.65 times.</u>
