Answer:
Carbon Dioxide absorbs and re-emits the infrared radiation.
Answer:
8.4 kW
Explanation:
Using the Stefan-Boltzmann law,
P = εAσT4
Where:
P: Radiation Energy
ε: Emissivity of the Surface. Check emissivity table below of common materials.
A: Surface Area, in m^2.
σ: Stefan-Boltzmann Constant, σ=5.67 × 10-8 W/m2•K4
T: Temperature
Plugging in values,
P = 0.85 x 3.328 x 5.67 x 10^(-8) x 205
P = 8383 W or 8.4 kW
Convert km to m. -> 320km=320000 m
Convert hours to seconds -> 4 hrs=14400 s
Divide the distance by time because v=d/t
320000/14400=22.22 m/s
Characteristics of refraction: When light travels from one medium to another, the frequency of light does not change. However, the velocity and wavelength change. When travelling from one optical medium to another with different refractive indices, a ray of light bends.
(Hope this helps!!)
The process is denitrification
