Final answer:
To calculate the charge that passes through the starter motor, we can use the formula Q = Ne, where Q is the charge, N is the number of electrons, and e is the charge of a single electron. Given that the car battery moves 3.75 x 10^21 electrons, the charge that passes through the starter motor is 6 x 10^2 C.
Step-by-step explanation:
To calculate the charge that passes through the starter motor, we need to use the formula:
Q = Ne
where
Q is the charge in coulombs
N is the number of electrons
e is the charge of a single electron (1.6 x 10-19 C)
Given that the car battery moves 3.75 x 1021 electrons, we can calculate the charge as follows:
Q = (3.75 x 1021) * (1.6 x 10-19)
Simplifying this calculation, the charge that passes through the starter motor is 6 x 102 C.
