4. Superman is very strong. In trying to impress Lois Lane, he stands on top of a 12-storey building (-50 meters tall), lowers a very tall and wide straw into a pool of Kool-Aid and tries to drink. a. b. Regardless of how strong superman's diaphragm is, what is the highest level above the pool's surface he can hope to raise the water to (normal day, 1 atm pressure outdoors)? Superman goes to university and now learns about hydrostatic pressure and realizes his mistake. He also learns about capillarity. In attempt number two, superman goes back to the same building, but this time he has a specialized very thin "straw" that perfectly wets water. How thin must the straw be for him to succeed in raising the water up the requisite 50m if (i) he is not sucking anymore (just pretending to, I guess) and (ii) he is "sucking" as hard as is possible.
