Two identically sized metal spheres are on insulating stands. The charge on sphere A is -4.0*10-6 coulombs and the charge on sphere B is -8.0*10-6 coulomb. What is the charge on Sphere B after they touch and separate? What is total number of excess electrons on Sphere A after they separate?

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

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

You can estimate the degree to which a bond between two atoms is ionic or covalent by calculating the
