Caculate the expectation value (r) for an electron in the ground state of the hydrogen atom. remember, the maximum of the radial ground state wavefunction, i'mar, is equal of the bohr radius. is the expectation value (r) larger, equal or smaller than i mar? give a brief explanation. b) (10 pts] using the expectation value (r )nim = 1/(aon) and the energy values for an electron in a bound state (nlm) of the hydrogen atom, show that the expectation values of the kinetic energy operator t and of the potential energy v are such that: 2(t)nim = -(v)nlm

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.
