Crown correct answers A crown is the very tip of the bore in which the exit plane is precisely ma- chined perpendicular to the bore axis Harmonics correct answers Barrel harmonics is the mea- sure of a barrel's ability to return to true upon fir- ing a round, and ensures that from shot to shot, a consistent barrel movement is achieved. Bedding and Stabilizing. correct answers Bedding is a process in which the stock and tang are infused with epoxy that surrounds the action and bar...

1. A decrease in the temperature of a gas sample in a closed container will always result in an increase in the: A. value of the PV / (RT) ratio. kinetic energy of individual gas molecules. C. gas pressure on the container. D. attraction between gas molecules. Correct Explanation: D. Since the temperature of a gas is proportional to the average kinetic energy of its molecules, decreasing the temperature will result in a decrease in kinetic energy. This decrease in kinetic energy will ...

The position of a particle moving along the x axis is given by x = (21 + 22t  6.0t 2 )m, where t is in s. What is the average velocity during the time interval t = 1.0 s to t = 3.0 s?A bullet is fired through a board, 14.0 cm thick, with its line of motion perpendicular to the face of the board. If it enters with a speed of 450 m/s and emerges with a speed of 220 m/s, what is the bullet's acceleration as it passes through the board?The position of a particle moving along the x axis is given ...
