Question
Chapter 38, Problem 14TYK
Summary Introduction
To review:
Controlling the car’s speed by a typical negative feedback mechanism while driving.
Introduction:
The negative feedback mechanism is a controlled process in which the feedback gives a negative signal (inhibiting signal), that means an opposite response. The moment when the body experiences something exceeding the normal range, the negative feedback mechanism reduces it to a normal range.
