Consider the following wave functions (where a, b, k, and a are constants): (i) ψ(x) = a sin(kx) (iv) ψ(x) = ae-ikx (i) ψ(x) = b cos(kx) (v) ψ(x) = be+ikx (iii) ψ(x) = a/x (a) determine which of the above func- (vi) ψ(x) be-ax tions are eigenfunctions of the momentum operator, px, and identify the correspond- ing eigenvalue. (b) determine which of the above functions are eigenfunctions of the kinetic energy oper- ator, kx, and determine the corresponding eigenvalue. 4. evaluate the momentum expectation values of the free particle wavefunctions ex and etilx (where k is a positive constant). what do your results tell you about the direction in which free particles described by each of these wavefunctions are moving?

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
