Consider the observables a -x2 and b -l: a) construct the uncertainty principle for ơaơb b) evaluate σβ for the hydrogen state ψη1m c) what can you conclude about (xy) in this state?

The electronic structure or chlorine is 2.8.7 what is the electronic structure of fluorine?

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.

Aseries circuit contains a 30 e resistor, a 20 resistor, and a 10 resistor. the power supply provides 100 v to the circuit the current in the 10 resistor, to two significant figures, is a.
