1. Imagine that a particle can exist in one of the three states: |0 > , |1 >, |2> . We now consider 2 such particles. How many distinguishable states are possible if the particles are (a) distinguishable (b) indistinguishable, classic (c) bosons (d) fermions. Write down the wave function of the system for all cases.

A string of length 8 m and a mass of 90 g is held under a tension of 105 N. A wave travels down the string that is modeled as y(x, t) = (0.01 m)sin[(12.11 m−1)x − (1,170.24 s−1)t]. What is the power (in W) over one wavelength?

A conducting bar of length D rotates with angular frequency w about a pivot P at one end of the bar (see the figure). The other end of the bar is in slipping contact with a stationary conducting wire in the shape of a circle (we only show a small part of that circle to keep the drawing simple). Between...
