Solar Constant

An earth- orbiting satellite has a solar energy collecting panel with total area 5 m^2 If solar radiations are perpendicular and completely absorbed, the average force associated with the radiation pressure is (Solar constant = 1.4 k Wm^(-2) )

Compute the surface temperature of the sun from the following data: Distance of earth from the sun R=1.469xx10^(11)m Radius of the sun r=6.928xx10^(8)m Solar constant S=1.39xx10^(3)Wm^(-2) Stefan's constant sigma=5.73xx10^(-8)Wm^(-2)K^(-4)

Compute the surface temperature of the sun from the following data: Distance of Mars form the sun =1.524AAU Solar constant of Mars =5.976xx10^(2)Wm^(-2) Stefan's constant =5.735xx10^(-5)Wm^(-2)T^(-4) Radius of the sun =6.928xx10^(8)m

The solar constant for the earth is about 1.8J//m^(2)//s . What is the solar constant for a black body situated on a planet which is situated at a distance of 0.3 times the distance of the earth from the sun ?

The solar constant is the amount of heat energy received per second per unit area of a perfectly black surface placed at a mean distance of the Earth form the Sun, in the absence of Earth's atmosphere, the surface being held perpendicular to the direction of Sun's rays. Its value is 1388 W//m^(2) . If the solar constant for the earth is 's'. The surface temperature of the sun is TK,D is the diameter of the sun, R is the mean distance of the Earth from the sun. The sun subtends a small angle 'theta' at the earth. Then correct options is/are:-

Would you expect the total energy of the solar system to be constant? What about the total angular momentum? Explain
