The starting motor of a car is turning too slowly, and the mechanic has to decide whether to replace the motor, the ca- ble, or the battery. The car’s manual says that the 12 V battery should have no more than 0.020 internal resistance, the motor no more than 0.200 resistance, and the cable no more than 0.040 resistance. The mechanic turns on the motor and mea- sures 11.4 V across the battery, 3.0 V across the cable, and a cur- rent of 50 A. Which part is defective?
a. the motor
b. the cable
c. the battery

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
