3. Water emerges from a small opening at a height h from the bottom of a large container, which is filled to a constant depth H. What is the distance R from the base at which water hits the ground? (A) (B)(C)(D) (E)

8. Which one of the following statements of the second law of thermodynamics is wrong? (A) It is impossible for a heat engine that operates in a cycle to convert its work input completely into heat. (B) It is impossible for a cyclical device to transfer heat continuously from a cold body to a hot body without the input of work or other effect on the environment. (C) No cyclical heat engine has a greater efficiency than a reversible engine operating between the same two temperatures. (D) In a reversible process the entropy of an isolated system stays constant; in an irreversible process the entropy increases. (E) None of the above is wrong.
