How are fire scenes different than regular crime scenes for investigators?Fire scenes are entirely different than the regular crime scenes because the evidence of a fire scene was most likely ruined or burned to ashes, the individual who did the crime is not usually present in the crime scene. This makes it a little harder to piece together the suspect and convict someone of their crimes

What is the blast effect?

The blast effect is what happens when arush o± gasses from the main point of the bomb blow outward over 7000 miles per hour. This is related to the second law of Newton which states the acceleration of the object will depend on the force that acts on it.

What are the two types of high explosives?

Two types of high explosives are both primary and secondary. The very difference of it all is that primary explosives can be easily detonated and extremely sensitive to heat and/or friction. The secondary explosives are like dynamite which are explosives.
