suppose you had three particles, one in state va(x), one is state w(x), and one in state uc(x). assuming va, yb, and ψ, are orthonormal, construct the three-particle states [analogous to eqs. (5.15), (5.16) and (5.17)] representing (a) distinguishable particles (b) identical bosons (c) identical fermions. keep in mind that the three-body wave function /(x1,x2, r3) must be com- pletely symmetric under the interchange of any two of the three particles in part (b) and completely antisymmetric under the interchange of any two of them in part (c) hint: there's a cute trick for constructing completely antisymmetric wave func- tions: form the slater determinant, whose first row is a (x),yb(x), e(x), etc. whose second row is /a(x2), t/b(x2), (2), etc., and so on. this procedure works for any number of fermions.

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.
