An oven emits of beam of hydrogen atoms. as each atom passes you, you do an experiment to measure the angular position of the electron with respect to the proton. you find that the probability of observing the electron around the proton is described by where ois the angle with respect to the z axis. a) is the atom in an angular momentum eigenstate? if yes, what are the angular momentum quantunm numbers of that state. if no, what super-position of eigenstates describes the system. b) can the atom be in an energy eigenstate? if yes, what is the minimum energy state it can be in? if no, why not.

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain
