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:-
