Two identical tuning forks A and B oscillate at 440 Hz. A person is located on a line in between the two forks. Her distance from fork A is 50 m and from fork B is 10 m. She walks toward fork A at 30 m/s. The speed of sound is 330 m/s. (Hint: What frequency does she hear from A? From B? Keep 5 significant figures when you do the calculation)

Shock Waves

Shock waves are common in continuum mechanics, and their dominance is attributable to the fact that they are stronger (or even less) compressible. Substantial perturbations propagated as sudden dynamic changes of a compressible medium supersonically. Shock waves are all around us in our daily lives. Lightning, earthquakes, volcanic eruptions, and meteorite impact all produce them in nature. Even the earth, which is protected by its magnetic field, generates a shock wave as in solar wind that travels around 20 Earth radiuses. These shock waves might be either constant, linked to the body, or unsteady, i.e., moving around with time. All of the shocks mentioned above can be damaging, so precautions must be taken to reduce their impact.
