Part C Would detecting Jupiter be easier or harder than detecting Earth? You may neglect any difference in reflectivity between Earth and Jupiter. Express your answer using three significant figures. ? Fraction reflected by Jupiter = Part A Calculate the fraction of the total emitted sunlight that reaches Earth. (Hint: Imagine a sphere around the Sun the size of Earth's orbit (area = 4Ta2), then calculate the fraction of that area taken up by the disk of Earth (area = Tr2 %3D Slanet). Earth's reflectivity is 29%). Express your answer using three significant figures. Fraction intercepted = 4.54x10-10 Submit Previous Answers Correct Part B Earth reflects 29% of the Sun's light. Based on this fact and your answer to part A, calculate what fraction of total sunlight is reflected by Earth. (Hint:Your answer will simply be the overall fraction of all the Sun's light that is reflected by Earth.) Express your answer using three significant figures. Fraction reflected by Earth = 1.32x10-10 Part C Would detecting Jupiter be easier or harder than detecting Earth? You may neglect any difference in reflectivity between Earth and Jupiter.
