In a heart pacemaker, a pulse is delivered to the heart 81 times per minute. The capacitor that controls this pulsing rate discharges through a resistance of 2.5 x 106. One pulse is delivered every time the fully charged capacitor loses 59.7% of its original charge. What is the capacitance of the capacitor?
