I NEED HELP!!!! THIS IS DUE TODAY OCT. 14, 2020 AT 11:59 PM!!!Keisha has two large dogs and a small dog. The dogs like to play tug-the-rope together. Each of these three diagrams shows one way that the dogs play together with the rope. Look at each arrow and the number that goes with it. They show the direction and amount of force each dog exerts on the rope. There are three illustrations of two dogs pulling at a toy rope. The left art should show two big dogs pulling on a rope toy each pulling with a force of 20N in the opposite direction. The middle art shows a big dog on left pulling to the left on the rope toy with a force of 20N and a little dog pulling to the right with a force of 12N. The right art shows the rope toy tied to a post, with both dogs pulling on different parts of the toy and in the same direction. One large dog pulls with a force of 20 N and the small dog pulls with a force of 12 N. Explain whether the forces shown in each diagram are balanced or unbalanced. Use math-based evidence to support your claim for each diagram.
