How much charge passes through a cross-sectional area of a copper wire in 0.8 s if I = 3.5 A?

1 C
-Work equation?

3.5 Amp = 3.5 Coulombs per second.

So, multiply that by 0.8 seconds.
That will be the answer, in Coulombs.

To calculate the amount of charge passing through a cross-sectional area of a copper wire, you can use the formula:

Q = I * t

Where:
Q = amount of charge (in coulombs)
I = current (in amperes)
t = time (in seconds)

In this case, you are given that the current (I) is 3.5 A and the time (t) is 0.8 s. Plugging these values into the formula, we get:

Q = 3.5 A * 0.8 s = 2.8 C

Therefore, the amount of charge that passes through the cross-sectional area of the copper wire in 0.8 s is 2.8 coulombs.
