Final answer:
To find the total coulombs of charge moved, multiply the number of electrons (3.75 X 10²¹) by the charge of one electron (1.602 X 10⁻¹⁹ C). The total charge moved is 6.00 C.
Step-by-step explanation:
To determine how many coulombs of charge were moved when a car battery moves 3.75 X 1021 electrons through the starter motor, we can use the fundamental charge of an electron and multiply it by the number of electrons moved. The charge of one electron is approximately 1.602 X 10-19 coulombs (C). Thus, multiplying the charge of one electron by the number of electrons gives us the total charge moved in coulombs.
Calculation:
Total charge (C) = Number of electrons × Charge of one electron
Total charge (C) = 3.75 X 1021 electrons × 1.602 X 10-19 C/electron
Total charge (C) = 6.00 C
To find the number of coulombs of charge moved when 3.75 x 10^21 electrons are moved through the starter motor, we need to know the charge of an electron. The charge of an electron is approximately 1.6 x 10^-19 coulombs. Therefore, to calculate the number of coulombs of charge moved, we can multiply the number of electrons by the charge of an electron:
3.75 x 10^21 electrons × 1.6 x 10^-19 C/electron = 6.0 x 10^2 C
Therefore, the correct answer is a) (6.00 C).
