Un capacitor de placas paralelas separadas por aire, de 5.8 μF, tiene una separacion de 5 mm y esta cargado a una diferencia de potencial de 400 V .
(a) Calcule la energia potencial y densidad de energıa almacenada entre las placas.
(b) Si se inserta un dielectrico con K = 2.7 entre las placas del capacitor, cual es ahora la energıa potencial
y densidad de energıa almacenada?.

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

What will a positive and a negative charge do if they are separated from each other?

If forces acting on an object are unbalanced. true or false
