Question

copper has one conduction electron per atom its density is 8.89 gram per centimetre cube and its atomic mass is 63.5 4 gram per mole if a copper wire of diameter 1.0 millimetre carries a current of 2.0 ampere what is the diff speed of the electron in the wire​

Answer 1

Answer:

here is ur answere

Explanation:

Copper has a one conduction electron per atom.its density is 8.89g/cm^3 and its atomic mass is 63.54g/mol.?

Density 8.89g/cm^3 = 8.89e+6 g/m^3

Atomic weight = 63.54g/ mol

Number of mol per m^3 is

8.89e6/63.54 = 139911.9 mol /m^3

1 mol contains 6.02e23atoms (Avogadro's constant).

Therefore 1m^3 of copper contains 6.02e23*139911.9 = 8.4 e+28atoms

V = I / (nAq) where A = 7.85e-7 m

= - 2 / (8.4e28*(7.85e-7) 1.6e-19)

V = - 0.000189 m/s
