Earth and Mars are both rocky planets, but Mars is half as far away again from the Sun as Earth, so radiation from the Sun is not as powerful at the surface of Mars as at the Earth’s surface.
Using the values in Table 2, calculate the amount of solar radiation intercepted by the surface of Mars. Give your answer in scientific notation, to the appropriate number of significant figures, and in the correct units.
Table 2 Values of solar constant (W m−2) and area facing the Sun (m2) for Mars.
Solar constant (W m−2)
5.20 × 102
Area facing the Sun (m2)
3.6 × 1013
The Attempt at a Solution
5.20x10(p-o)2 / 3.6x10(p-o)13 = 1.444444444x10(p-o)15 -
1.4x10(p-o)15 W m
Can anyone tell me what i am doing wrong if my answer is wrong (which i am sure it is)
