Which of the following is classified as low velocity in blasting terms?

Explanation:
In blasting terms, low velocity refers to an explosive with a comparatively slow detonation front—the energy travels through the charge much more slowly than in high-velocity explosives. Black powder is the classic example of this slow category; it has a far slower detonation velocity than modern energetic explosives. Dynamite, nitroglycerin, and RDX are designed for rapid energy release and have much higher detonation velocities, so they fall into the high-velocity group. Therefore, the substance classified as low velocity is black powder.
