Consider two electrons in a one-dimensional box of length l. the potential energy is zero inside the box and infinite outside of it. the potential energy of the electron-electron interaction is v(x_1, x_2). a) first, assume that v(x_1, x_2) = 0. find the ground state energy and write down the ground state wave function considering spatial and spin state symmetry. b)now v(x_1, x_2) = l v_0 delta (x_2 - x_1). assuming that v_0 is small find the correction to the ground state energy.

If forces acting on an object are unbalanced. true or false

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
