The period of a pendulum of length b centimeters undergoing small oscillations is given by T = 2pi(sqrt(b/g)) seconds, where g = 980 centimeters per second per second. Suppose the length of the pendulum changes as a function of temperature so that db/dr= 0.08 centimeters per degree Celsius. a. Find dT/dr when b = 20 centimeters.
