The average intensity of the solar radiation that strikes normally on a surface just outside Earth’s atmosphere is 1.4 kW/m2. (a) What radiation pressure pr is exerted on this surface, assuming complete absorption? (b) For comparison, find the ratio of pr to Earth’s sea-level atmospheric pressure, which is 1.0 * 10^5 Pa.
Assuming the earth is a perfect absorber, what is the force of the sun's radiation on the earth? Given the intensity of the sunlight on the earth is I, the earth-sun distance is R and the radius of th earth is r. Only answer with the given variables
The Earth reflects approximately 38.0% of the incident sunlight from its clouds and surface. (a) Given that the intensity of solar radiation is 1 340 W/m2, what is the radiation pressure on the Earth, in pascals, when the Sun is straight overhead? (b) Compare this to normal atmospheric pressure at the Earth’s surface, which is 101 kPa.
