Ahydrogen atom, whose normalized stationary state is described by inlm), where n is the main quantunm number and l and m is the quantum numbers belonging to l and lz: nlm) = 1 as usual the following operators is introduced here we neglect spin and fine structure a hydrogen atom is descripted by the normalized wave function: (|210) + |211)) account for the fact that lp) is an energy state, and find the corresponding energy. is lp) an eigenstate for 12 1. 2. find the mean of l in the state lp). account for the fact, that around the standard deviations on the observables lx and ly the following must be the case calculate l+lw) and l_lp). find the expectation value(l.) and(ly〉 in the state 14) 3. 4.

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
