A 10 gauge copper wire carries a current of 26 A. Assuming one free electron per copper atom, calculate the magnitude of the drift velocity of the electrons.

-3.71 * 10^-4 m/s

Step-by-step explanation:

A 10 gauge copper wire has a standard cross sectional area of 5.26

=

density of copper,  is 8.80 × 103 kg/m3

The atomic mass of copper is 63.54 * 10^-3 Kg/mol.

Avogadro’s number, 6.02 × 1023 atoms/mol

Density of copper's free electrons =

= 8.3374 * 10^28

drift velocity of the electrons =

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
