If 10J of work are done in 2 seconds, what is the power?

A5 nc point charge is at the origin and a second 3 nc point charge is on the x-axis at x = 0.8 m. find the magnitude and direction of the electric field on the x-axs at x = 0.2 m. you may express the direction by letting positive field mean the positive x direction

This is the number of complete movements of a wave per second.

An element becomes a positively charged ion when itloses protons.loses electrons.gains electrons.gains neutrons.
