Answer:
Explanation:
v = I / (n q A)
where A is the cross sectional area (you are given diameter, so A = (pi/4) * d^2), n is the number of charge carriers in a volume, and q is the charge of each carrier (-1.60x10^-19). I is the current, in Amps.
You will need to either convert your diameter from inches to centimeters or you will need to convert your volume in cc to cubic inches. I'd convert diameter.
