ACE
lawn tennis
The air pressure inside the can is always higher than the air pressure outside the can. The air is compressed into the can along with the tennis balls.
If the receiver had hit the ball but then they had hit it out, it would be the servers point. Because they did not hit it out. [I'm currently taking a tennis class and basically asked the same question].
No, only the person standing diagonal from the server at the baseline may return
In a single game, the score would be 30-40 (where the server has 30 and the receiver has 40). This is known as a break point.
Tennis comes to mind.
Fault
There is a door handle on the inside and the outside. Neither uses a tennis ball.
The inside line is the boundary for tennis when playing singles. The outside line is the boundary in Doubles.
The receiver must stand diagonally opposite to the server. For example, if the server is on the right side (thus serving to the server's left service box), then the receiver must stand to the receiver's right to be diagonally opposite to that of the server.
