Next, the students start a new game. Now, a fourth student is playing for the team with gray shirts: Model B:

During this new game, the ribbon moves to the left (towards the students in the gray shirts). On the model above, draw force vectors above each team that describes this movement.

Iam looking for this answer too!

Electoral current force mechanical advantage if the wheel and axle is 2 n and the output force is 20 n

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
