Final answer:
The effective resistance of a car's starter motor when 150 A flows through it as the car battery applies 11.0 V to the motor is 0.0733 Ω.
Step-by-step explanation:
In order to find the effective resistance of a car's starter motor, we can use Ohm's Law, which states that resistance is equal to voltage divided by current. In this case, the voltage is 11.0 V and the current is 150 A. By substituting these values into the formula, we get:
R = V/I = 11.0 V / 150 A = 0.0733 Ω
Therefore, the effective resistance of the car's starter motor is 0.0733 Ω.
