comment Why wet is dark?
The original image source seems to be victoria.ac.nz/scps/about/staff/pdf/darkerwhenwet.pdf, which also describe this in a detail, together with experimental verification of the theory.

I think this nicely adds to the the current top answer, which talks about air/sand and water/sand reflection, but misses the water/air transition description. Moreover, your answer is very easy to understand thanks to the picture. Perhaps a legend describing Ri, a and p would even improve it?

comment Where does the extra kinetic energy come from in a gravitational slingshot?
The answer seems too long and not well structured to me (like a wall of text). Also, while it contains the key point - the answer to the subject of the question: Where does the energy come from? - It comes from the planet, it is not highlighted, it is hidden in the middle of the answer.

This explanation cannot be possibly true for the sand or soil - no fibers to bend on it.

comment Why wet is dark?
The answer sounds plausible, however there is one thing which is still unclear to me: why when the wet surfaces freezes it turns bright again (often even brighter than before)? Refraction index of ice is more or less the same as for water. Perhaps the the ice not filling the space in between the grains as liquid water did?

comment Why does the air flow faster over the top of an airfoil?
As the accepted answer (and the wikipedia animation) shows, it flows even faster than equal-time condition would suggest.
