As a result of the motion through the magnetic field, a charge in the rod will experience a force f⃗ =qv⃗ ×b⃗ : the usual part of the lorentz force for charges moving through magnetic fields. this force will push the charge in the rod, and hence this force will be an electromotive force (emf). for now, we shall say that the force that moves the charges is due to an induced electric field einduced, which will enable us to calculate the emf. the fact that there is an induced electric field at all is rather subtle, because there is no closed loop that encloses some changing flux. therefore, a method that does not involve faraday's law must be used to solve this motional emf problem. in fact, this problem is a good introduction to some of the ideas behind faraday's law. find the y component of the induced electric field einduced.

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 380j of energy to the room?

The bubba chump shrimp company processes and packages shrimp for sale to wholesale seafood distributors. the shrimp are transported to the main plant by trucks that carry 1,000 pounds (lb) of shrimp. once the continuous flow processing of the shrimp begins, no inventory is allowed in buffers due to spoilage and all of the shrimp must be processed within 12 hours to prevent spoilage. the processing begins at the sorter, where the trucks dump the shrimp onto a conveyor belt that feeds into the sorter, which can sort up to 500 lb per hour. the shrimp then proceed to the desheller, which can process shrimp at the rate of 400 lb per hour. however, after 3 hours and 45 minutes of processing, the desheller must be stopped for 15 minutes to clean out empty shrimp shells that have accumulated. the veins of the shrimp are then removed in the deveining area at a maximum rate of 360 lb per hour. the shrimp proceed to the washing area, where they are processed at 750 lb per hour. finally, the shrimp are packaged and frozen. what is the daily process capacity of the processing plant (excluding the packaging and freezing)?
