Consider the wavefunctions, and compare to the probability density: measure the period of oscillation for a given set of well parameters. write down the equation for the wavefunction of an infinite quatum well. given the energy of the state selected, does the period match what is expected? where do the "real" and "imaginary" part of the wavefunction come from. what happens to the wavefunction as the energy approaches the top of the well. explain this observation. why are there only 1-4 states in this quantum well when in the quantum free-electron model there is a quasi-continuum of eneergy states? (ie what is different? )

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
