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.

WebBecause the Sun (or any star) is a sphere of radius R, we state it has a surface: A = 4 π R2. With the Sun's radius R = 6,96 × 108m, we can compute its surface temperature T: There is also another way to get the value of T by using Wien's law: λmaxT = b where λmaxis the most intensive wavelength, and b the Wien constant (b = 2,90 × 10-3mK).

WebProminences are dense clouds of material suspended above the surface of the Sun by loops of magnetic field.
