I know EMC2, I know what the letters stand for. I mean what is the application. I need someone who knows it so good he can explain it with simple words, or using an example. Thanks. I really want to know.Note: I am no physicist.
most likely the toilet. I'm sure people used other stuff rather than toilet paper.
There was an excellent episode on this subject on Mythbusters long story short eighteen inches of water is enough to protect one against even a .50 caliber round, but a shotgun slug fired on the perpendicular could prove fatal a a depth of more than three feet. I personally suspect that this is due to the fact that water cannot be compressed and the much higher velocity of most rounds causes them to dissipate much of their energy upon contact with the water whereas the relatively slow shotgun slug moves the water aside allowing greater penetration.
