The solutions to schrödinger's equation for the hydrogen atom are wave functions that are characterised by three quantum numbers n, 1 and mi. for each quantum number answer the following questions: (i) what property of the quantum state is determined by the quantum number? (ii) write down an expression for that physical quantity, defining terms as neces- sary. (b) the energy levels obtained by the solving schrödinger's equation for hydrogen are degenerate. explain what this means and give an expression for the degeneracy of an energy level. (c) if dirac's full relativistic treatment is used, how are the energy levels changed? (d) explain the lamb shift

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
