5. Positive feedback systems increase or decrease the deviation from the basal condition?
Submit
6. Will a well damped system reduce or increase the number of oscillations?
Submit
7. Will a high gain system bring the system back to the normal quicker or slower?

8. An increase in the flow of urine is called
Submit
9. In a control system what is the "error signal?"
Submit
10. Can equilibrium be unstable and stable?

Explanation

Stable equilibria return to normal after a disturbance, whereas unstable equilibria will not return to normal after a disturbance.If you push a stable equilibria away it will come back to its original state.
