oh nevermind! awesome thankyou so much for the help Doc

well replacing that into the equation i have i still get a way off answer?

In atoms with a single electron (essentially the hydrogen atom), the energy of an orbital (and, consequently, of any electrons in the orbital) is determined exclusively by n. The n = 1 orbital has the lowest possible energy in the atom. from wikipedia

its not 1?

ok here's where I'm not as of now. did i make an error in one or more of the steps?

oh ok umm is there anywhere that i should know what n_f does equal. does the hydrogen part give a clue or ?

so is dc just a steady current then?

hi all, quick question with regards to bohr's model From what energy level did an electron fall if it emits a photon of 9.38 x 10^-8 wavelength when it reaches fround state within a hydrogen atom? this is a textbook question so i know the answer is n = 6 attached is a copy of my...

still not gettin why the dc can't do this?

because its a direct current? lol

hey all, another quick question for ya The modern system for transmission of electric energy using alternating current (AC) originated with an inventor named Nikola Tesla. An American entrepreneur, George Westinghouse, bought the rights to Tesla's system and managed to convince consumers that...

Hi all, I'm on the final question of an assignment, unforunatly its not really a calculation or anything and i can't find any information on it i thought maybe someone could help me out 13. At a coal-fired electric generating station, heat from the burning coal is used to drive a steam...

everyone stumped like me

Hello, Quick question I'm having a hard time finding much information, or at least information I'm absorbing. I'm just supposed to write a paragraph on: Could the same accident at Chernobyl happen in a CANDU 3 reactor? Anything to help get me started anyone?

sorry the image didn't show up like planned i'll type it out. b) Calculate the speed of the electron moving into the electric and magnetic fields... we have a diagram in part a) that shows an electron moving into the plane of the page. were given: V = 2000 V between charged plates d=...
