You are picking up your partner from a mall.  Though you can see your partner, your partner cannot see you.  You proceed to yell, hoping that the sound of your voice will help direct your location.  If the air is dry, and the temperature outside is 14.01 ∘ C, and you estimate that you are about 487.49 meters away from your partner, how long (in seconds) does it take your partner to hear your voice after you have yelled out?

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.
