question 5

Multiple Choice

The resistivity of copper at 20ºC is 1.7 $\times$ 10^-8 $\Omega$ · m and the number of electrons per cubic centimeter is 8.47 $\times$ 10²².If you take the average speed of the electrons to be equal to their root-mean-square speed (at T = 300 K) of 1.17 $\times$ 10⁵ m/s,it follows that their mean free path, $\lambda$ ,must be

• B)1.86 nm
• C)2.35 nm
• D)2.89 nm
• E)None of these is correct.
