The Earth reflects approximately 38.0% of the incidentsunlight from its clouds and surface. (a) Given that theintensity of solar radiation at the top of the atmosphere is1 370 W/m2, find the radiation pressure on the Earth, inpascals, at the location where the Sun is straight overhead.(b) State how this quantity compares with normal atmosphericpressure at the Earth’s surface, which is 101 kPa.
The radiation pressure exerted by the Sun on theEarth counteracts the gravitational attraction and puts theEarth into an orbit that is farther from the Sun than if therewere no radiation pressure. It can be shown that the distanceadded to Earth’s orbital radius is given by 1Frad>Fg2r, where Frad isthe radiation force exerted on Earth by the Sun, Fg is the gravitational force between the Earth and Sun, and r is the average orbital radius. (a) If the intensity of sunlight that strikesEarth is 1360 W>m2, what is Frad, assuming the Earth is a perfect absorber? (b) Assuming r = 1.50 * 1011 m, what is Fg?(c) What is the additional distance added to Earth’s orbital radiusby the radiation pressure?
