I am trying to set up some 555 timers to either: 1 - open a valve for a short period of time and then close it 2 - activate some sort of switch that will push a button to open the valve it will be much more simple for me if I could find something that will push a button when triggered by a...

figured it out, thanks though

the clue i was given is that energy is constant and equal to the potential energy at the initial position

I can't seem to figure this one out. A particle at rest is attracted to a center of force by the relation F=-mk^2/x^3 what is the time it takes for the particle to get to the force center from a distance d in terms of d and k? I can't seem to find any equations that will help me out on...

well the wavelength of a photon is simply h/p, for the electron i can't seem to find a formula for the wavelength

If a photon and an electron have the same energy how would i show that their wavelengths differ (relativistically)? Furthermore, how would I find the energy when the difference between the wavelength of the photon and electron is a factor of 4? thanks
