Suppose that at a given time a quanton has the (unrealistic) wavefunction shown. If we per- form an experiment to locate the quanton at that time, what is the probalitiy that the result will be greater than zero? Explain your reasoning. (Assume that y(x) = 0 everywhere out- side the region shown. The size of the vertical and horizontal scales in not relevant.) *(x)

A cat chasing a mouse slides off a deck. The cat lands 1.8 m from the deck. The deck was 2.2 m high. What was the cats initial velocity

need help with this question A neutron beam of initial kinetic energy E, is divided into two beams at point O by some mechanism. Thereafter the beams proceed on the path OAC and OBC without a phase change at the corners A and B to interfere with each other at point C. Here OACB is a square of side I, tilted at an angle 0 above the horizontal. Mass of the neutron is m, Planck's constant is h and acceleration of free fall is g. the possible expression(s) for angle 0 at which a Maxima is detected at C is/are Horizontal 2hl/2mE, m°gl 2hl, /2mE, -h² 2h?
