La d. d.p. entre dos puntos es de 220 000 V. ¿Qué trabajo debe realizarse para mover una carga de 4.5 microC de un punto a otro del conductor?

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?

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.

When you hold a rectangular object, how does the area of the side that is resting on your hand affect the pressure and the force that the object exerts?
