In regular baseball rules, the ball is still live, even if it hits the ground first, until it hits the batter, then it becomes a "dead ball". If it never hits the batter, its still a live ball.
it is a foul.
A pitched ball can hit the ground before crossing home-plate. In most cases the batter would not swing and the pitch would be called a ball. But, if the batter decides the swing, the ball is still in play after hitting the ground and the batter may not hit the ball and receive a strike, or he may foul the ball, or hit a base-hit.
It is not a dead ball until someone downs (touches) it.
It is a live ball. If the batter reaches first base safely, it is a hit. If the batter is thrown out a first, it's an out.
The ball is dead whenever the umpire calls "time", whenever it goes out of play, when it becomes a foul ball, whenever a pitch hits a batter, or whenever a batted ball hits a runner (and a few other circumstances). It doesn't matter whether the pitcher has it or not. On the other hand, it can't be put back _in play_ until the pitcher has it and is on the rubber.
A pitched baseball that hits the ground is a live ball, therefore you may swing at it. If you miss, it is a strike. If you hit it foul, it is a foul ball. If you hit it fair, whatever play results is legal.
if the umpire is inside the base path, then it is a dead ball... no pitch --- if the umpire is outside the base paths then it is a live ball
It depends. Is the ball being thrown or is it hit. If it's hit off the bat and hits a base runner it's a dead ball and the runner is out if the ball has not passed a fielder. If the ball has already passed a fielder then the ball is live and the runner is not out. It is as if it never happened. If it hits the runner when it is thrown it is perceived as if it never hit the runner.
