If a ball carrier falls down on top of an opposing player and does not otherwise touch the ground, he is not considered down by contact and may continue to advance the ball.
Some part of the ball carrier's body, other than his hands or feet, has to make contact with the ground for him to be considered down(Technically, a knee or elbow or helmet has to make contact with the turf for the carrier to be down).
This is true for all levels of football play: HS, NCAA, NFL.
It depends. If your knee is touching the ground, or if the ball is, you are considered "down by contact". If both the ball and your knee are off the ground, you are still able to get up and run. (This has happened numerous times with players falling over an opposing player, landing on their feet and continuing on)
No, it is considered a completed pass. A receiver may go to the ground to catch the ball, as long as it doesn't hit the ground.
No, his tactic was splitting his army into two and outflanking the Union Army under General Joseph Hooker. This was an offensive tactic as opposed to the defensive tactic of holding high ground.
General Giap believed that the Tet offensive would cause the citizens and the Army of South Vietnam to lose confidence in their government.
When the player who has the ball has a knee or elbow on the ground when in contact with a player from the opposite team. When the player that has the ball touches any other body part besides his hands on the ground and is in contact with a player from the opposite team.
The ground is not at firm, traction is lessened, sliding is more frequent, the ball become more slippery leading to handling errors, the players take on more water in their clothing and mud adding to weight carrying

In the CEC, if pipe fill is used using table 6, ground wires are not included in the count. If pipe fill is used using cross sectional area of conductors and pipe then the ground wire must be included along with the current carrying conductors. A continuous metallic conduit system is considered a ground return path for fault currents.
passenger carrying systems that are raised on pylons above ground.
he can get up and run if he has not been touched yet. then he has to be tackled to be down, not "touched". The above is true in the NFL...the touch must have caused the fall or happened while the knee or elbow is on the ground. In college or ANY level below the play ends when the players knee or elbow touches regardless of the reason.
on the ground of course
No. A ground wire is a non-current carrying conductor and cannot be used for hot or neutral.

To get better traction into the ground and to not slip
That's just two wires twisted together, one carrying a signal and the other carrying the ground for that same signal.
No, tornadoes do not have to touch the ground to be considered a tornado. A tornado is considered to be a rotating column of air that extends from the base of a thunderstorm to the ground. However, not all tornadoes reach the ground, and those that do are most likely considered more dangerous.
