Priming {Ans: The direction in which the shock wave travels through the explosive charge}Internal Charge {Ans: Charges that are placed in boreholes in the target. P=D^2/250 or P=0.004D^2. Note: Diameter=circumference/3.14}Ring Charge {Ans: A band of explosives that completely encircles the tree}1 inch {Ans: Less than 5 lb}Charge calculations {Ans: Six step problem solving format}tamping {Ans: To keep as much explosive force as possible on the target, pack material around the charge to fill any empty space.}
