An Iron Wire Has A Cross Sectional Area Of 7 30 X 10 6 M2 Carry Out Steps A Through E To Compute The Drift Speed Of 1 (98.74 KiB) Viewed 40 times

An iron wire has a cross-sectional area of 7.30 x 10-6 m2. Carry out steps (a) through (e) to compute the drift speed of the conduction electrons in the wire. (a) How many kilograms are there in 1 mole of iron? kg/mol (b) Starting with the density of iron and the result of part (a), compute the molar density of iron (the number of moles of iron per cubic meter). mol/m3 (c) Calculate the number density of iron atoms using Avogadro's number. atoms/m3 (d) Obtain the number density of conduction electrons given that there are two conduction electrons per iron atom. electrons/m3 (e) If the wire carries a current of 39.0 A, calculate the drift speed of conduction electrons. m/s Need Help?
