Acceleration EMF (a) A long straight rod with cross sectional area A and conductivity σ accelerates parallel to its length with acceleration a. Write down the Drude-like equation of motion for the average velocity v of an electron of mass m in the rod relative to the motion of the rod itself. Show that, in the absence of an external electric field, there is a steady solution that corresponds to a current 1 Aơma/e flowing in the wire. Assume that...

A large pipe with a cross sectional area A1=1.2 m2 has water flowing through it. The pressure in the pipe there is maintained at atmospheric pressure. The pipe then descends 3.7 m and narrows to a new cross sectional area A2. Water exits the pipe there into an environment at atmospheric pressure. What must the cross sectional area A2 of the pipe be in m2 if the water is exiting the pipe with a speed of 9.8 m/s?

The maximum rated current for a copper wire of cross-sectional
area 2 mm^2 is 20A. (a) What is the corresponding current density
in A/m^2? (b) On the assumption that each copper atom contributes
one conduction electron, calculate the electronic drift velocity
corresponding to this current density. (Avogadro's number =
6.02E10^23 atoms per mole; atomic weight of copper = 63.5; density
of copper = 8.92 g/cm^3.) (c) Use the observed conductivity to
calculate the average collision time for an electron in...
