Consider a particle of mass m in a 1d infinite square well potential with v(x) 0 if 0 xa, and v(x) oo otherwise. (a) show that an energy eigenstate of the time-independent schrödinger equation with e inside the well is not possible. do not rely on the answer from problem 3.1, but instead work explicitly with the schrödinger equation, its respective solution for this case, and construct your argument using the boundary conditions where the wave function must vanish 0 (b) similarly, show that an energy eigenstate with e < 0 inside the well is also not possible use the general solution to the ordinary differential equation to which the schrödinger equation reduces in this case

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
