A defibrillator has a 130-mF capacitor charged to 2000 V and an internal resistance of 30 W. If the resistance of the path of the discharge through the patient is 170 W, how much energy is delivered to the patient upon complete discharge of the capacitor?
a. 170 J
c. 220 J
b. 30 J
d. 240 J
Question 2
A container is filled with water and the pressure at the container bottom is P. If the container is instead filled with oil having a density of 0.80 that of water, what new bottom pressure results?
a. a pressure < P
b. the same pressure P
c. a pressure > P
d. This is unable to be determined with the information given.
