Aparticle of mass m is confined to a box with infinite walls at x = 0 and x = l. at time t = 0 the particle is in the state \(x) = sin (") + sin (27"). [5] (a) normalise the state y(x). (b) find the location inside the box where the particle is forbidden to exist. [5] (c) what is the shortest time after which the probability density p(x, t) = 4(x, t)/2 returns to its value at time t = 0?

In the 1980's, congress authorized the u.s. department of energy to build the wipp facility in the chicuahuan desert in new mexico. what is the purpose of wipp?

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
