The passage of a strong shock wave through the human body, for example, causes severe damage owing to the large instantaneous pressure change.
How strong is a blast of 1 kg of TNT?
An overpressure of 230 kPa (33.4 psi) corresponding to detonation of 1 kg of TNT generates a blast wind of over 240 km/h measured near the point of origin. The mechanism of injury may be predicted by an individual’s distance from a detonation.
What is a shockwave from a bomb?
Shock wave, strong pressure wave in any elastic medium such as air, water, or a solid substance, produced by supersonic aircraft, explosions, lightning, or other phenomena that create violent changes in pressure.
What are the three main causes of damage and injury from explosions?
Primary injuries (PBIs) are caused by the effect of transmitted blast waves on gas-containing structures; secondary injuries, by the impact of airborne debris; tertiary injury, by the transposition of the entire body because of blast wind or structural collapse; quaternary injuries, by exposure to explosive products ( …

How much TNT would it take to destroy the earth?
The gravitational binding energy of Earth is about 2.2*1032 J, corresponding to 5*1022 tons of TNT. The largest weapon tested so far (Tsar bomba) had 50 megatons, we would need 1015 or 1 quadrillion of them.
How fast is a shockwave in mph?
At 50 seconds after the explosion, when the fireball is no longer visible, the blast wave has traveled about 12 miles. It is then traveling at about 784 miles per hour, which is slightly faster than the speed of sound at sea level….Overpressure.
| Peak overpressure | Maximum Wind Speed |
|---|---|
| 10 psi | 294 mph |
| 5 psi | 163 mph |
| 2 psi | 70 mph |
What kind of blast injury is due to toxic materials absorbed by the body?
Quaternary blast injuries: Quaternary blast injury is everything else not caused by primary, secondary or tertiary mechanisms. Examples include burns, angina, crush injuries, asthma or COPD exacerbations due to dust, smoke or toxic fumes.
Who are bomb and heavy in Sonic the Hedgehog?
Bomb and Heavy in the Archie Comics. In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, Bomb and his partner Heavy were created by Dr. Robotnik, but defected upon becoming self-aware. After temporarily joining the Chaotix, Bomb and Heavy disappeared.
What are the different types of sonic weapons?
Sonic weapon. Some sonic weapons are currently in limited use or in research and development by military and police forces. Some of these weapons have been described as sonic bullets, sonic grenades, sonic mines, or sonic cannons. Some make a focused beam of sound or ultrasound; some make an area field of sound.
What’s the difference between a hypersonic and a sonic weapon?
“Ultrasonic weapon” redirects here. It is not to be confused with hypersonic weapon. Sonic and ultrasonic weapons ( USW) are weapons of various types that use sound to injure or incapacitate an opponent. Some sonic weapons make a focused beam of sound or of ultrasound; others produce an area field of sound.
What causes a sonic boom in RuneScape?
Caused by a sonic boom, or otherwise extremely loud sound, representing the concussive force and damaging effect on the ear. This is a very rare damage type but can also be created by arbitrary elemental effect spells. Examples: Thanks for contributing an answer to Role-playing Games Stack Exchange!
