Textbook Question
Chapter 5, Problem 48SDP
In the past, waterfowl hunters used lead shot in their shotguns, but this practice resulted in lead poisoning of unshot birds that ingested lead pellets (along with gravel) to help them digest food. Steel and tungsten are being used as replacement materials. If all pellets have the same velocity upon exiting the shotgun barrel, what concerns would you have regarding this substitution of materials? Consider both performance and environmental effects.

Select all true statements.
ANFO explosive is often preferred because using bulk explosives is cheaper, less
labor intensive during loading and they fill the entire blast hole diameter.
Emulsion explosives should not be used in strong and massive rocks where a
high detonation pressure and high detonation velocity is required to break the
rock.
During rock fragmentation by blasting, the reflection of the compression wave at
the free face into tension and shear waves contributes to additional cracking
between the free face and the blast hole.
When metals or other reactive elements are present in the composition of an
explosive, less oxygen is required for a an oxygen-balanced reaction.
Illustrate both the adverse and therapeutic effects of factors presented in Fick’s law?
Which among the depositional sedimentary environment are considered likely to contain organic matter and eventually be the source of hydrocarbons?
