yes
tennis regulations include but are not limited to: foot faults - you cant step over the line before you serve the ball you cant touch the net until the point is over the ball cant bounce twice before you hit it no distracting the player during the point(yelling, etc)
When the server serves the ball directly into the opposite side of the court with no player from the other team touching the ball (or they touch the ball but the second pass is unplayable).
out
Stay down on the ball. Don't aim for the line, aim 2-3 feet inside the line to ensure a good shot...don't worry about where the opponent is, focus on the ball and finishing up over your shoulder.

Yes, we believe it would be considered an over and back because you are touching the ball when you cross half court.
No, you CANT step over the serving line when you serve in volleyball. The "ref" on the side of the court, on the stand, will call it, and give a point to the opposing team. Usually the line judge should call it....
Let's play tennis! A good way to recognize prepositions is to imagine a tennis net. Now think of a tennis ball as a preposition (e.g., the ball can go "through" the net, the ball can go "over" the net)
It is called a "let" in tennis when the ball hits the net because "Filet" is the French word for net and the game originated in France.
Aftar 80 over
The three kinds of errors that can result in losing the serve in sports like tennis or volleyball are: Serving the ball out of bounds. Failing to get the ball over the net. Committing a foot fault by stepping on or over the service line.
it doesn't matter where your tennis racket is just as long as it hits the tennis ball
