Consider a complete set of 1-d orthonormal stationary states , {¢n(x)} (let them be the energy cigenfunctions of the hamiltonian h). a general wavefunction x, 1) can be expanded in this basis with coefficients of expansion c (a) find the general expression for the expectation value (h) wherej is an integer power to raise the operator. reduce this expression as much as possible (though the answer is still no more than a few lines). (b) explain the consequences of an observation of the energy of this system. what is measured and what happens to the wavefunction? explain how this is consistent with your previous answer (c) write the uncertainty of an energy measurement ae. simplify as much as possible, if at all

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
