1. Absorbing Cerebrospinal Fluid [11] Cerebrospinal fluid is continually produced and reabsorbed by the body at a rate that depends on its current volume. A medical researcher finds that absorption occurs at a rate of 0.35 mL/min when the volume of fluid is 150 mL and at a rate of 0.14 mL/min when the volume is 50 mL. Answer the following questions: (a)  Suppose the absorption rate A, is a linear function of the volume V . Find the equation of the linear function using the information above and then sketch a graph of A (V )vs V .[7] (b)  State in your own words what does the slope of the graph that you calculated in part (a) above represent?[2] (c)  Find the A-intercept of the graph and what does it represent?[2]

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
