(c) Show that the average solar energy incident on the earth is -2 calorie/(cm 2 minute) and the radiation pressure on a perfect absorber is 4.47 × 10 –6 N/m 2. [Assume that no solar radiation is absorbed by the atmosphere] WebApr 27, 2015 · Apr 27, 2015. According to the equation E = n ⋅ h ⋅ ν (energy = number of photons times Planck's constant times the frequency), if you divide the energy by Planck's constant, you should get photons per second. E h = n ⋅ ν → the term n ⋅ ν should have units of photons/second. Answer link.

WebThe Radiant heat energy is a notion which is rather more nicely explained by Stefan’s law.This law elucidates how the heat is radiated! It states that The amount of heat which is radiated (E) by a flawless black body for a second in a provided unit area is directly related to the fourth power of its absolute temperature (T). The Radiant heat energy formula is … WebSo if Earth's surface radiation global average is about 398.2 w/m^2, then the day/night numbers work out to about 7.7% variation between them, or +/- 15.5 degrees, about 413.7 watts/m^2 during the day and about 382.7 at night. That's a pretty good estimate I think. te amo by calema
