A cordless electric shaver uses energy at a rate of3.5 W from a rechargeable 2.9-V battery. Each of the charged particles that the battery delivers to the shaver carries a charge that hasa magnitude of 1.6 x 10-19 C. A fully charged battery allows the shaver to be used for its maximum operation time, during which 2.0 x1022 of the charged particles pass between the terminals of the battery as the shaver operates. What is the shaver's maximumoperation time?NumberMOUnits◄►

You are working in a laboratory, using very sensitive measurement equipment. Your supervisor has explained that the equipment is also very sensitive to electrical discharge from human operators. Specification tables for the equipment indicate that an electrical discharge providing even a very small amount of energy of 250 μJ is enough to damage the equipment. Your supervisor wants to install an apparatus that will be used to remove the electrical charge from individuals’ bodies before they touch the equipment. To do this, she asks you to estimate (a) the capacitance of the human body and determine (b) the charge on the body and (c) the electric potential of the body, relative to a point infinitely far away, corresponding to the energy transfer that will damage the equipment.
