Copper (Cu) has FCC crystal structure. Atomic mass of Cu is 63.55 gmol-1 and radius of a copper atom is 0.128 nm, mean speed of conduction electrons in Cu is 1.5 × 10 and frequency of vibration of the Cu atoms at 27 ° is 4 × 10 . Nordheim’s Coefficient of Au in Cu is 5500 Ω − AQM a) Calculate the atomic density of copper b) Estimate the drift mobility of electrons in Cu c) Find the resistivity of pure Cu d) Find the resistivity of Cu if 1 at.% of Au is mixed in Cu.

Me for the love of god. i've been working on this assignment for 3 days and i don't understand the speeches at all ive read both 4 times over and i don't understand either of them if your right i will give you brainlest (i think that's how you spell it) and 99 pts. for this assignment, you will write an evaluation of either of two historic passages. • patrick henry’s “give me liberty, or give me death! ” speech (1775) • frederick douglass’s address, “what to the slave is the fourth of july? ” (1852) 1. what is the speaker’s viewpoint? what is his claim? type your answer here.
