Proving Air Is Matter
One way to prove that air is made of matter is to blow up a balloon. Before you add air into the balloon, it is empty and shapeless. When you puff air into it, the balloon expands, so you know it is filled with something—air is taking up the space.
Answer:
Team 2
Explanation:
Team 1 pulls with a frce of 150N
Team 2 pulls with a force of 200N
In a tug-of-war, the goal is to pull the other team over a certain distance and this is determined by the force applied.
If the two team pulls with equal force, there wold be no net force and the teams stays in the same position.
In this case however, team 2 pulls with a force greater than team 1. There is a net force of 50N in favor of Team 2. This means team 2's force would neutralize that of team 1 and the excess force would be use in pulling Team 1
