Derivation of Bohrs Equations for the Oneelectron Atom
Bohr set about to devise a model that would explain the observed line spectra of oneelectron atoms, such as H, He+, Li2+. The model Bohr used was based on Rutherfords
conclusion from his gold foil
John’s automobile has a threeliter SI V6 engine that operates on a fourstroke cycle at
3600 RPM. The compression ratio is 9.5, the length of connecting rods is 16.6 cm, and
the engine is square (B = S). At this speed, combustion ends at 20° aTDC.
