Graduate Can an Electron Gain All Three Electronvolts of Energy Through Bouncing?
Sorry, I put in a draft version instead of the 'real' one. PF is a great forum and my desire is to contribute, not to detract. I did not mean to include the first sentence (big mistake). The sentence was an overview to help me focus on providing a response to your post. I fully intended...- pzlded

Graduate Can an Electron Gain All Three Electronvolts of Energy Through Bouncing?
Sir, I think there is a problem with your units. Electronvolts do not equal volts qV \neq V An ElectronVolt qV is the amount of voltage's energy that converts to kinetic energy when an electron passes through 1 volt (V) of electric potential difference. In a synchrotron, each...- pzlded

Ok, consider the units: VOLTS are Joules per coulomb http://en.wikipedia.org/wiki/Volt V = \frac{J}{C} An ELECTRONVOLT has the unit 'Joules' 1 eV = 1.602 17×10^{-19} Joule. Energy conversion tables list electronvolts, not volts. For example: http://onlineconversion.com/energy.htm- pzlded

The energy unit ELECTRONVOLT differs from eV, (eV is volts or energy per charge. Wikipedia explains the energy unit 'electronvolt'. http://en.wikipedia.org/wiki/Electronvolt- pzlded

Graduate Can an Electron Gain All Three Electronvolts of Energy Through Bouncing?
Yes if you mean the energy required to bring an electron from infinity to the 1V spot. For example: a 1.5 volt battery does not have one contact point on an electron and another contact point near the electron. As with any unit of energy, electronvolts can be independent of any particular...- pzlded

Graduate Can an Electron Gain All Three Electronvolts of Energy Through Bouncing?
Let there be three electronvolts of energy between a tube’s cathode and plate with a voltage of one volt. Let thermionic emission release one electron at the cathode. From the definition of electronvolt (the energy a point charge gains when it travels through one volt), that electron gains one...- pzlded

High School NET Force on Massless Body: Acceleration & Spring Force
Hi D.H. I rebel at the thought that physics is cut and dry. I do not object to the idea that classical physics is an idealization of the real world; I object to the idea that the difference between classical physics, quantum physics and relativity are almost by definition ‘unexplainable’... -

High School NET Force on Massless Body: Acceleration & Spring Force
Hi Mark, The forces pulling on the spring could have been the result of a mass suspended by the spring. Perhaps I should have mentioned that if F1 equals –F2, the weight of the mass equals the pull on that end of the spring, equals the pull on the supporting bracket. When F1 does not... -

High School NET Force on Massless Body: Acceleration & Spring Force
Hi Redbelly, In practice, acceleration is limited by the speed of light. For example: the speed of light limits quantized acceleration of a neutrino. The original problem did not specify that F1 and F2 are equal or that the force is gravitational. Magnetism, the electrostatic field of a... -

High School NET Force on Massless Body: Acceleration & Spring Force
I suppose some neutrinos are supposed to be massless and acceleration could occur if the neutrino interacted with an atom (converting neutrino energy to kinetic energy). If F1 and F2 are constant, but unequal, the massless spring would likely instantly reach the speed of light. -

Undergrad How can I calculate the temporal characteristics of a pulsed solenoid circuit?
I think that it is extremely difficult to build a durable non-superconductive 5T magnet Albeit the following would not produce a pulsed magnetic field, perhaps it is possible to modify an existing superconductive magnet, to produce a square wave of magnetic energy. Commercial 5T... -

Undergrad How can I calculate the temporal characteristics of a pulsed solenoid circuit?
Hi Lichen, Pulsed solenoids are outside my area of expertise; the following is my ‘opinion’. I am surprised about your use of heat shrink-wrap on a potentially high temperature magnet. I also thought you would want a high density of coils (square wire windings with high temperature... -

Undergrad How can I calculate the temporal characteristics of a pulsed solenoid circuit?
Hi Lichen, I assume you have given due consideration to the usual design requirements. For example, minimizing electrical resistance has the following potential benefits - faster response, good thermal efficiency, lower operational cost, reduced applied voltage requirements (increased... -

Graduate Electric Displacement field? what is it?
From the URL http://farside.ph.utexas.edu/teaching/316/lectures/node116.html The equation relating magnetism to current is: \oint B\cdot\partial r=\mu_{0}(I+I_{D}) D in this equation violates Ampere’s law. There is generally a problem with relating point charges to voltage...- pzlded
