The Galilean transformation between coordinate systems that you may have used in PHY 2048 (or maybe on the SAT) can be written for position as:

x' = X

y' =y

z' = z - ut

A) What am I assuming is the difference between the primed and unprimed coordinate systems here? B) What are the velocity transformations between the primed and unprimed coordinate systems (i.e., vx, Vy, Vz and v'x, v'y, v'z)?

A) The neutron mass is 1.675 x 10-27 kg. Express the proton mass in eV/c2, keeping 4 significant figures

B) The mass of the electron is 9.109 x 10-31kg. Express this in eV/c2.

C) What is the mass of the hydrogen atom in eV/c2?
