Physics

An iron wire has a cross-sectional area of 5.70 âœ• 10âˆ’6 m2. Carryout steps (a) through (e) to compute the drift speed of theconduction 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 ironper cubic meter). _mol/m3
(c) Calculate the number density of iron atoms using Avogadro'snumber. atoms/m3
(d) Obtain the number density of conduction electrons given thatthere are two conduction electrons per iron atom.electrons/m3
(e) If the wire carries a current of 20.0 A, calculate the driftspeed of conduction electrons. ____m/s
