... a. Assuming the only force acting on the electron is the electrostatic force due to the stationary proton, show that the orbital period of the electron (the time it needs to revolve around the proton once) equals 1.5 10-16 s. b. Based on part a., calculate the time-averaged current i in the electro ...

... The factor by which the electric field is reduced is known as the dielectric constant k (or r). If the gap between the plates of a capacitor is filled with dielectric material, the voltage between the plates for a given charge will also be reduced by the factor k. Since C = Q / V, this means that C ...

Acoustomagnetoelectric Effect in Graphene
... Graphene[17] is a single layer of carbon atoms with zero band-gap. Within the low energy range (ε < 0.5eV), carriers in graphenes are massless relativistic particles with effective speed of V F ≈ 106 ms−1 (V F being the Fermi velocity). One of the major limitations of Graphene sheet is lack of band ...

Woodward effect
The Woodward effect, also referred to as a Mach effect, one of at least three predicted Mach effects, is part of a hypothesis proposed by James F. Woodward in 1990.The hypothesis states that transient mass fluctuations arise in any object that absorbs internal energy while undergoing a proper acceleration. Harnessing this effect could generate a thrust, which Woodward and others claim to measure in various experiments. If proven to exist, the Woodward effect could be used in the design of spacecraft engines of a field propulsion engine that would not have to expel matter to accelerate. Such an engine, called a Mach effect thruster (MET), would be a breakthrough in space travel. So far, no conclusive proof of the existence of this effect has been presented. Experiments to confirm and utilize this effect by Woodward and others continue.
