A doubly charged ion is accelerated to an energy of 27.0 keV by the electric field between two parallel conducting plates separated by 2.00 cm. What is the electric field strength (in V/m) between the plates

Anybody wanna ? (picture included? )

Most of the volume of an atom is occupied by the

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
