Created by StemPy LabA capacitor is charged to , and a capacitor is charged to . Both are disconnected from their batteries. They are then joined together so that the positive plate of each is connected to the negative plate of the other. The energy lost in the process (as heat and radiation) is

← An electric dipole of dipole moment 2.0 × 10⁻⁸ C m is held in a uniform electric field of 5.0 × 10⁴ N/C, with its dipole moment at 60° to the field. How much work must an outside agent do to turn the dipole slowly until its moment points exactly opposite to the field?You have 24 identical cells, each of emf 2 V and internal resistance 1 Ω. They are to be arranged in m identical parallel rows, with n cells in series in each row, to send the largest possible current through an external resistor of 6 Ω. The best arrangement and the current it gives are →
