7. (6pts) Consider F(x, y, z) = (y2 + z cos x)i + (3xy2 + 1)j + sin æk. Show that F is a conservative vector field and then compute SF. dr where C is any curve from (0,0,1) to (0,2,3).
Find parts a and b. Consider the three-dimensional cubic well V = {(0 if 0<x<a, 0<y<a, 0<z<a), (infinity otherwise). The stationary states are psi^(0) (x, Y, z) = (2/a)^(3/2)sin(npix/a)sin(npiy/a) sin(npiz/a), where nx, ny , and nz are integers. The corresponding allowed energies are E^0 = (((pi^2)(hbar^2))/2m(a^2))(nx^2+ny^2+nz^2). Now let us introduce perturbation V={(V0 if 0<x<(a/2), 0<y<(a/2)), (0 otherwise) a) Find the first-order correction to the ground state energy. b) Find the first-order correction to the first excited state. 1. Consider the...

For following can I get explanation for the answers. (step by step solution would be nice). Prove, for any Hermitian operator , and any arbitrary state If>, that the quantity <fIÑ If> is real. The expectation value of any quantity represented by a Hermitian operator is always real. This is the reason for using Hermitian operators to represent measurable quantities. For each of the following matrices, state weather it is unitary and/or Hermitian. [1] « [1] -[9] «» (e :)...
