A parallel plate capacitor has plates of dimensions 20cm by 20cm separatedby 2mm. the dielectric constant of the material between the plate is 5and the plates are connected to a voltage source of 500v. calculate a).the capacitance, b)the charge on either plate c)the energy density d) the total energy stored in the capacitor ​

The sun generates both mechanical and electromagnetic waves. which statement about those wave is true?

Ann walks 80 meters on a straight line 33 ∘ north of east starting at point 1. draw ann's path. represent ann's walk with a vector of length 80 meters. draw the vector starting at point 1. the length given in the display is in meters.

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
