Asap which of the following happens when the swing moves from position a to position b? potential energy of the student is converted to kinetic energy. kinetic energy of the student is converted to potential energy. both potential energy and kinetic energy of the student increase. both potential energy and kinetic energy of the student decrease.

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.
