The ground state eigenstate |0⟩ is the unique state annihilated by the lowering operator aˆ. show algebraically that the excited states of the oscillator are non- degenerate, by showing that a degeneracy would imply a degeneracy of the ground

Which one of the following research methods can show cause and effect

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
