Note that this is the maximum possible kinetic energy because W is the minimum energy necessary to liberate an electron. The threshold frequency, the minimum frequency the photons can have to produce the emission of electrons, is when the photon energy is just equal to the work function: The Compton effect Although photons have no mass, they do have momentum, given by:
Conclusion: The most reliable cars. While these two surveys may vary, it is evident that cars made by Toyota (including Toyota, Lexus and Scion, have a generally impressive record on reliability, so are a good place to start if you are looking for a reliable car. In terms of American-made cars, Buick comes out top.
The Infiniti Q70 is the only Nissan product to make the top 10 list of most reliable cars. Not only that, but it's the only luxury sedan on the list to offer a long-wheelbase version. So if you need a personal limo with impeccable dependability, this is pretty much your only choice.
