ITEMS Practice similar Help me with this INFO CONCEPT REVIEW < Previous If R denotes the reaction of the body to some stimulus of strength c, the sensitivity S is defined to be the rate of change of the reaction with respect to c. A particular example is that when the brightness ofa light source is increased, the eye reacts by decreasing the area R of the pupil. The experimental 40 + formula R has been used to model the dependence of R on when R is measured in sq mm and is measured in the appropriate units of brightness. Find the sensitivity.
