- Lorentz’s Law relates the quantity of charge, the magnetic field strength, and velocity of the charge to the _______________on the charge moving through the field. Faraday’s Law states that the faster the flux through a loop increases or decreases, the larger the _______________ developed across the loop. Unlike the field lines of electric charges which leave the + charge and can go on forever, not returning to a – charge, magnetic field lines must terminate at the _______________ pole of the magnet. The term B·AsinΘ calculates what quantity? ____________________ Lenz’s Law is states that when a magnetic field changes (increases or decreases) and cuts across a wire coil, an emf will be induced to ____________________ the change.arrow_forwardA docs.google.com/forms/d/e.

- Solar cells generate a potential difference when exposed to sunlight. In an experiment, you wish to charge a rechargeable battery by connecting it in series to an array of solar cells. You perform the experiment outdoors, in direct sunlight, when the intensity of solar radiation is 1000 W/m². However, your solar cells only have an efficiency of 11% (that is, only 11% of the sunlight power transmitted to the solar cells is delivered to the rechargeable battery). While the circuit is connected, you measure at one instant the potential difference across the battery to be 5.30 V and the current in the circuit to be 0.27 A. What is the area of the array of solar cells? m2arrow_forwardPart A You've recently read about a chemical laser that generates a 20.0-cm-diameter, 24.0 MW laser beam. One day, after physics class, you start to wonder if you could use the radiation pressure from this laser beam to launch small payloads into orbit. To see if this might be feasible, you do a quick calculation of the acceleration of a 20.0-cm- What speed would such a block have if pushed horizontally 95.0 m along a frictionless track by such a laser?
