Draining a tank A cylindrical water tank has a valve at the bottom. When the valve is opened, the water drains out, and rate at which the water flows out is proportional to the fill level because the pressure in the tank is proportional to the mass of water in the tank. Therefore the decrease of mass in the tank is given by , where m is the mass of water in the tank and α is a constant. (a)...

Problem 3: A solenoid that has 50 turns per centimeter has a radius of 3 cm. There is a single circular loop with radius of 2 cm in the very center of the solenoid. The axes of both the solenoid and the loop are the exact same. The current through the solenoid varies with time based on the formula below beginning at a time we will define to be t = 0. What is the emf generated in the single...
