Bob and Dan are pushing a couch together, Bob with a force of 6 N and Dan with a force of 5 N. The couch exerts a force of 8 N in the opposite direction (of Bob and Dan). Are forces balanced or unbalanced?
Group of answer choices
The forces are balanced since Bob and Dan are pushing in one direction and the couch is pushing in the other.
The forces are unbalanced since there is a net force of 11 N
The forces are unbalanced since there is a net force of 3 N

Explanation:
Answer-To find total force of Bob and Dan, you add (6 N + 5 N = 11 N).Then you subtract, 11 N – 8 N = 3N (since the couch pushes in the oppositedirection),forces are unbalanced, it will move in the direction that Bob and Danare pushing.Use the examples to help you on the following net force problems.Show yourwork!1.Calculate the net force if Jane pushes a piano across the floor with a force of25 N and Bob pushes the piano in the same directionwith a force of 15 N.Areforces balanced or unbalanced?What will happen to the piano’s motion?Showyour work!25 N + 15 N =40 NForces are not balanced, the piano will move in the directionthat it’s being pushed.2.Mike pushes a box with a force of 30 N forward, but the box resists with aforce of 10 N the other direction.What is the net force?Are forces balanced orunbalanced?What will happen to the motion of the box?Show your work!30 N – 10 N=20 N forwardForces are not balanced, the box will move in the direction thatit’s being pushed.
Answer:
The reactivity series is a series of metals, in order of reactivity from highest to lowest. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series.
