Answer 1
6.0 C
INCORRECT

I=q/t. When you run the numbers through this equations, you get a bigger number for the answer. return to top























Answer 2
20. C
INCORRECT

I=q/t. When you run the numbers through, you get a bigger number than this. return to top



























Answer 3
360 C

INCORRECT

I=q/t. When you run the nuymbers through this equation, you get a much larger number. return to top


























Answer 4
720 C

CORRECT

I=q/t.
6.0 A=q/120 s
q=720 Coulombs return to top


























What's this question really asking?

What is the charge passes a point after 120 seconds, when there is 6.0 Amps? return to top
