Answer 1

The effective resistance of a car's starter motor in this situation is approximately 0.0415 Ω.

Step-by-step explanation:

To calculate the effective resistance of a car's starter motor, we can use Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor.

The formula to calculate resistance is R = V/I, where R is the resistance, V is the voltage, and I is the current.

In this case, the given information is that the current flowing through the starter motor is 265 A and the voltage applied is 11.0 V.

Using the formula, we can substitute the values:

R = 11.0 V / 265 A

Simplifying the equation, we get:

R = 0.0415 Ω

Therefore, the effective resistance of the car's starter motor in this situation is approximately 0.0415 Ω.
