Please answer this question:
An aluminum wire having a cross-sectional area of 2.10 ✕
10−6 m2 carries a current of 6.00 A. The
density of aluminum is 2.70 g/cm3. Assume each aluminum
atom supplies one conduction electron per atom. Find the drift
speed of the electrons in the wire.
Please answer correctly!!!! Thank you so much in advance!
