2a) Venus and Mars orbit the Sun at average distance of 0.72AUand 1.52 AU, respectively. what is the solar flux at each planet? (1 astronomical unit is defined as the average distance from Earthto the Sun, approximately 93 million miles)

b) how does the solar flux of Venus compare to that of Earth(larger, smaller. by what factor)?

c) Venus has an albedo of 0.8 and Mars has an albedo of 0.22.using the answer to part (a), determine the effective radiatingtemperatures of these planets.

d) how do the effective radiating temperatures determined inpart (c) compare with the value for earth? what about the trend ineffective temperature with distance from the sun is surprising?

e) the mean surface temperatures of Venus and Mars are 730Kand 218 K. using the answer to part (C), determine the magnitude ofthe greenhouse effect on each planet

f) how do the results of e compare with the magnitude of thegreenhouse effect on Earth?
