Answer :
Final answer:
Low explosives typically have a velocity of detonation less than 1000 meters per second. While this number can vary, option C is the most accurate for the multiple-choice question. Low explosives, such as black powder and smokeless powder, undergo a deflagration rather than a detonation, resulting in a slower explosion.
Explanation:
In the context of explosives, low explosives are usually defined as having a velocity of detonation substantially less than 1000 meters per second. However, it's worth noting that this number could be somewhat variable depending on the specific type of explosive and the conditions under which it's detonated.
For your multiple-choice question, the correct answer emphasizing the typical definition would be option C. 1000 meters per second. Providing a specific numerical cutoff is somewhat arbitrary, as the properties of explosives can vary widely. But in broad terms, low explosives are often grouped as those with velocities of detonation less than 1000 meters per second.
Examples of low explosives include black powder and smokeless powder. These explosives deflagrate (burn) rather than detonate, creating a relatively slow, subsonic explosion that is less shock-sensitive.
