Mitigating data leakage from insider threats is a difficult challenge. Businesses must take advantage of every opportunity to better understand how employee behavior and intent relates to security issues, and to make security a priority in every aspect of business operations.
The velocity of a projectile with respect to the muzzle at the instant the projectile leaves the weapon.
I would agree. Physics would probably show that the amount of gas expelled through the gap between cylinder and barrel comes to a maximum after a certain barrel length (of course depending on powder and wideness of gap). From then on, the longer barrel would not lose any compression anymore, and therefore the velocity would once again go up.
