When a body is travelling faster than the local speed of sound, often a shock wave is created. Describe the physical causes of such a shock wave.
(See attachment for full question)

a. In fluid dynamics, a shock wave is a strong pressure wave. In compressible fluids such as air, disturbances such as pressure changes caused by a solid object moving through the medium propagate through the fluid as pressure waves traveling at the speed of sound. When the cause of the disturbance is moving slowly relative to the speed of sound, the pressure wave ...
A body traveling faster than the local speed of sound is examined. The physical causes of such a shock waves are given.
