High explosives detonate at how many feet per second?

1) 3300 or higher
2) 3000 or higher
3) 3600 or higher

Answer :

Final answer:

High explosives detonate at speeds of 3600 feet per second or higher, known as the detonation velocity. This speed is crucial for the correct operation of fireworks and other explosive materials.

Explanation:

The question you've asked pertains to the speed at which high explosives detonate. The correct answer is 3) 3600 or higher feet per second. This speed, also known as the detonation velocity, is the speed at which the shock wave travels through the explosive material. It varies depending on the type of the explosive. For instance, explosives like TNT and C-4 have detonation velocities around 6900 meters per second and 8000 meters per second respectively, which translate to over 22000 and over 26000 feet per second, respectively.

Interestingly, this speed is especially important when it comes to things like fireworks displays, as per your examples. The fuse of a firework is set to ignite the explosive material at a specific moment in order to achieve the maximum height and spectacle. When a shell is shot into the air, it reaches a certain height before exploding and this height is determined by the initial velocity, angle of launch, and timing of the fuse.

The detonation velocity is a crucial factor in ensuring the safety and effectiveness of these displays, similarly to other applications of explosives, including mining and construction.
