Those lines are baselines, if you are referring to the boundary lines on both sides of the tennis court which run parallel to and are at the greatest distance away from the net.
The Base Line is the Line that ends the doubles alleys. it is the line that is farthest from the net
Just lines. Nothing fancy. Unless you mean... yes. The line farthest to the back is the base line. The line closest to the net is the service line. There you go.
The tennis net height at the center of the net should be 3' and the post end 3' - 6" above ground.
it is the first horizontal line from the net.
The farest line from the net parralell from the net. The server stands behind it.
The service line is the line that borders the service box and is parallel to the net.
It is the third law of motion because it has to do with action reaction things. Tennis ball hitting the net is the action, and it falling to the ground is the reaction. I hope this helped.
The baseline in volleyball is where you would serve from. Or if you don't serve that far back, it is considered the out line. The farthest line from the net.
Well a tennis net it usally the size if a tennis net soya that's the size\

Tennis uses bigger rackets and have different rules. A badmitten racket has a lingetshaft with a small head. Also a badmitten net is up offthe ground unlike a tennis net. Lastly badmitten uses a birdie, not a yellow tennis ball.
A typical tennis net is 42 feet.
