    Physics Depth Study Advanced Mechanics

    Hi, I just got my first year 12 assignment which is a depth study of advanced mechanics. I had one idea of investigating the motion of rockets and satellites. I could even do something with circular motion or projectile motion, taking air resistance into consideration. I just don't what to do or...

    Use non-degenerate perturbation theory to solve the following problem: Consider a string of length L, that is perturbed by having its density be slightly higher between x=L/4 and x=L/2. You should assume the density increase is uniform along the stretch. How do the wave vectors change? How...
