Which statement best describes the effect of tamping pressure on fuse rate?

Explanation:
Increasing tamping pressure makes the explosive column more dense and tightly confined, reducing air voids. This allows the flame from the fuse to propagate through the material more quickly, so the fuse burn rate increases. In other words, greater tamping pressure speeds up how fast the fuse burns. The idea that tamping has no effect or only changes color isn’t supported by how density and confinement influence burn speed.
