d) Show that the resistivity can be expressed (via the familiar notation) as, m p= ne't here m is the electron mass; t is the period of time that elapses between two subsequent collisions, the electron undergoes with copper nuclei throughout its chaotic motion in the body of copper (supposing that the current carrying cable is made of copper). Hint: Write F=eE, i.e. the electric force reigning on the electron. Write also the acceleration a=F/m, an electron is subject to, based on the Newton's law of motion.
