Now solve the schrödinger equation for the helium atom using the finite element method. add the hartree and exchange – correlation potentials to your program, see equation (-1/2∙d^2/(dr^2 )-2/r+v_h (r)+v_c (r))v(r)=ϵu(r). make an initial guess for the density and iterate to self – consistency. determine the ground state energy and wave function.

Suppose you were asked to find the torque about point p due to the normal force n in terms of given quantities. which method of finding the torque would be the easiest to use?

In what direction does the medium move relative to the direction of the wave? explain.
