WebFeb 18, 2011 · Flux=EAcos (theta) The Attempt at a Solution So what I have written is "When the sun is lower in the sky, the angle theta between the sun and given area approaches 90, meaning cos (theta) approaches 0, meaning flux is smaller. The weather gets colder, since not as much heat is transferred from the sun. So is this right? WebMechanical Engineering questions and answers. The energy flux associated with solar radiation incident on the outer surface of the earth's atmosphere is 1366 W/m2. The diameters of the sun and the earth are 1.39x109 m and 1.29x107 m, respectively. The distance between the sun and the earth is 1.5x1011 m. a. What is the emissive power of … on the list meme

WebAs the distance from the Sun increases the surface area of the sphere grows by the square of the distance. That means that there is only 1/d^2 energy falling on any similar area on the expanding sphere. Now lets try it for another real place. Mars is at a distance of 1.5 AUs from the Sun. 1/d^2 = 1/1.5^2 = 1/2.25 = 44%.
