I bought a wireless network card a month ago so other computer users at home could access the Internet using laptops via ad hoc and everything works well except one thing. When data is being transferred through the wireless network, there appears an annoying noise in the speakers that is way too...

Homework Statement The system consists of an electron and a positron, which are rotating around each other. Using Bohr's theory of the hydrogen atom, what are possible orbits' radius (from the system mass center) and possible energy equation. Homework Equations The Attempt at a...

May be, bet don't recall. Thank you for the reminder. Will check them out.

Could anyone help solve a problem how to find absorption lines in hydrogen atom from n=10 (n - principal quantum number). I know that not all quantum jumps of an electron in atom are possible, thus I don't know how many different emission lins will be from this energy level where n=10.

It is so, but forgot that scientists still use Latin language for easier communication. Perpetual motion machine, as I found in the reference, actually violates both of the thermodynamical laws. First, because the only result of this hypothetical mechanism would be work done by a system greater...

Trying to find something about eternity engine to find something about eternity engine on the net or more precisely about unsuccessful attempts to build one and exactly about the theory that claims it is not possible. If anyone knows some source for a material, please let me know.
