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
Answer: The phase change for A and B respectively is condensation, freezing.
Explanation:
A process in which gaseous state of a substance converts into liquid state is called condensation.
For example, conversion of steam into water.
A process in which liquid state of a substance converts into solid state is called freezing.
For example, conversion of liquid water into ice.
Thus, we can conclude that the phase change for A and B respectively is condensation and freezing.
