How can positive feedback influence the behavior of a system? O A. It can cause instability as the amount of input decreases to zero.
B. It can cause instability as output increases uncontrollably.
O c. It can help maintain stability by balancing inputs and outputs.
D. It can help maintain stability by ensuring that inputs steadily
increase.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
