Sketch the wave-function of the ground state of a particle of mass m which is con- fined in one dimension within a square potential well of infinite height, centred at x = 0 and of width a between x = ?a/2 and x = a/2. What type of function is that? If the infinite potential well is replaced by a potential well of finite height, sketch the new ground state wave-function. Explain qualitatively how the ground state energy changes in...

Consider a particle of mass ? in an infinite square well of width ?. Its wave function at time t = 0 is a superposition of the third and fourth energy eigenstates as follows: ? (?, 0) = ? 3i?3(?)+ ?4(?) (Find A by normalizing ?(?, 0).) (Find ?(?, ?).) Find energy expectation value, <E> at time ? = 0. You should not need to evaluate any integrals. Is <E> time dependent? Use qualitative reasoning to justify. If you measure...

Derive the wave propagation equation for particle motion collinear with the direction of propagation. Assume a homogeneous, isotropic, linear-elastic, infinite, continuum medium. Follow your class notes, and clearly identify all assumptions made along the way. Then, assume the solution to the wave equation, i.e., the particle motion, replace into the differential equation and …. conclude!

Consider a very small particle of mass, m, dropped in a fluid. The particle experiences a drag force, FD. The constant that relates the drag force to the velocity V is K. Determine the distance covered as the partcile accelerate from rest to 50 percent of its terminal velocity, Vt, in terms of K, m, and acceleration due to gravity, g.
