An intuitive approach: As a moving object travels through a fluid, the fluid particles hitting the object transmit information with the speed of sound to the surrounding fluid particles about their encounter with the body. If the speed of the moving object is smaller than the speed of sound the surrounding particles have time to react and "get out of the way"(i.e. the streamlines begin to curve to compensate for the presence of the body) since the perturbation caused by impact propagates with speed of sound. But if the moving object travels with a speed higher than the speed of sound then the surrounding particles can't react(information about the collision hasn't arrive to them prior to the object reaching them). That's how the shock wave is formed. Now, the normal shock is a special case when the speed of the moving object is exactly the speed of sound (or Mach number equals one). In this case you can imagine that the molecules in front of the object form a "wall" perpendicular to the moving direction of the object.

How many amps is a normal shock?
the normal shock for human being is 250-300mA.
How do you shock a flatline to revive a patient?
To revive a patient with a flatline, a defibrillator is used to deliver an electric shock to the heart. This shock helps to restore the heart's normal rhythm and can potentially revive the patient.
An Airman has received a gunshot wound and appears to be going into shock You realize he may be going into shock because his pupils are?
larger than normal size
Why does electricity shock you?
Electricity can shock you because it disrupts the normal electrical signals in your body, causing muscles to contract involuntarily and potentially leading to injury or harm.
What is the full name of the device that is used to shock the heart back into a normal rhythm?
The full name of the device used to shock the heart back into a normal rhythm is an Automated External Defibrillator (AED). It delivers an electric shock to the heart in cases of cardiac arrest, aiming to restore a normal rhythm. AEDs are commonly found in public places and are designed for easy use by non-medical personnel.
What do defibrillator do to the heart pump?
'shock' the irregular rythme hopefully back into a normal one
How density and MACH number change across normal shock wave?
Across a normal shock wave, the density of the flow increases as the shock compresses the gas. The Mach number decreases; it transitions from supersonic (greater than 1) upstream to subsonic (less than 1) downstream of the shock. This change occurs because the shock wave converts kinetic energy into thermal energy, resulting in a rise in pressure and temperature. Consequently, the flow properties adjust to accommodate the conservation of mass, momentum, and energy across the shock.
Can a neutral wire shock you?
No, a neutral wire should not shock you under normal circumstances because it carries the return current from an electrical circuit and is typically at a similar voltage as the ground.
Can Undead Dragons in Dragon Cave be bred?
No, they must be obtained via the normal method.~Eustic
What would cause a car battery to shock you?
A car battery can shock you simply because it has stored energy and power. This is normal, but can be dangerous depending on if the person has built up a static charge.
How much shock do you use for a 24ft pool with a chlorine lock?
Three to four times the normal rate
Can your phone cause an electric shock?
Under normal use, your phone will not cause an electric shock. However, if there is a faulty charger or damaged equipment, there is a small risk of electric shock. It is always recommended to inspect your charging equipment regularly for any damage or wear.
