Assuming the Sun to be a spherical body of radius R at a temperature of TK, evaluate the total radiant powered incident of Earth at a distance r from the sun where r_0 is the radius of the Earth and sigma is Stefan's constant.

Assuming the Sun to be a spherical body of radius R at a temperature of TK, evaluate the total radiant powered incident of Earth at a distance r from the sun where r_0 is the radius of the Earth and sigma is Stefan's constant.

Assuming the Sun to be a spherical body of radius R at a temperature of TK, evalute the total radiant powerd incident of Earth at a distance r from the sun where r_0 is the radius of the Earth and sigma is Stefan's constant.

Assuming the sun to have a spherical outer surface of radius r radiating like a black body at temperature t^(@)C . The power received by a unit surface (normal to the incident rays) at a distance R from the centre of the sun is where sigma is the Stefan's constant.
