Two sound waves of the same frequency and amplitude are broadcast from speakers at opposite ends of a theater. In the middle of the theater, you hear a sound 6 dB louder than that from either speaker. Which of the following is true?
The two waves are 45° out of phase in the middle of the theater.
The two waves are 90° out of phase in the middle of the theater.
The two waves are 180° out of phase in the middle of the theater.
The two waves are in phase in the middle of the theater.

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
