Any object in a liquid/substance will experience a force called upthrust. This force is not dependent on the weight of the object, rather the amount of volume it takes up within the substance. When the ob...

F=BQv so B=F/Qv (Q is the charge of an electron, 1.6 x10^-19 C) so B=4.32 x10^-16 / (1.6 x10^-19 x 500) = 5.4 T

Current, I, is related to voltage by Ohm's law, I=V/R. As the capacitor discharges, the current will decrease as less charge is "released" from the capacitor. From Ohm's law, w...

The difference in potential between the two Ds of a cyclotron accelerate the particles across the gap. The direction of potential difference switches every half cycle to keep the particles accelerating. T...

The path upon which light propagates is determined by Fermat's Principle. This says that light will always travel along the path of least time. Now, we often think of the speed of light as a constant, but...
