The conduction electrons in a metal can be considered for some purposes as an ideal gas.
A) What is the average thermal kinetic energy 3/2kbT of an electron at 300 K?
B) What is the corresponding velocity?
C) Calculate the ratio of this velocity to the drift velocity found in this example: ((A heavy-ion accelerator produces a beam of 10^15 oxygen nuclei per second. The charge on an oxygen nucleus is +8e. Find the beam current in amperes.
