Consider the hamiltonian for the two-dimensional motion of a particle of mass j. j- in a hru. n1onic oscillator potential: (a) show that the energy eigenvalues are given by en = (n + 1)/iw. where the i n t e g e r n = n 1 + n 2 , w i t h n 1, n 2 = 0 , i , 2 , . . (b) expresstheoperatorlz=xpy- /¥,; (~ i ~ ) al= -. x+-px 2 h j. j-w ~ a*~ i a) and a2= - y+-py 2 / i j. j-w ~ and the corresponding raising operators a)' and al .give a symmetry argument showingthat[h, iz]= 0. it indeed vanishes. (c) determine the correct linear combination of the energ) eigenstates with en- ergy £ 1 = 2nw that are eigenstates of lz by diagonalizing the matrix repre- sentation of lz restricted to this subspace of states.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
