Answer:
25N
Explanation:
Assuming the lab is on earth:
w = mg = 2.5 (9.81) = 25N
<em>Ten games</em> will be played.
The first team can be any one of 5 . For each of those, the opponent can be any one of the other 4 .
Number of ways to pair them up = (5 x 4) = 20 ways .
<em>BUT</em> ... Whether the Reds play the Blues, or the Blues play the Reds, it's the SAME GAME. Each possible game shows up twice in the list of 20 ways. So there are really only 10 different pairs ==> <em>10 games</em> .

Answer:
Tension: No, Force of Gravity and Air Resistance: Yes.
Explanation:
The air resistance and the correspondent component of the force of gravity will do work since both they are parallel/antiparallel to the direction of motion. Tension will not do work, since its perpendicular to the direction of motion.
