Find the radiation pressure of solar radiation on the surface of earth. Solar constant is 1.4kWm−2
A body of dimensions 2m×3m×4m is acted upon by a force of 50N on the top surface (2m×3m). The pressure due to the force on that surface is
The earth receives solar radiation at a rate of 8.2 J/cm2 - minute. Assuming that the sun radiates like a blackbody, calculate the surface temperature of the sun. The angle subtended by the sun on the earth is 0.53∘ and the Stefan constant σ=5.67×10−8W/m2 - K4.
