Suppose you are designing an amplifier and loudspeaker system to use at a country concert. You want to make it as loud as possible. How can you design the system to maximize the volume? Explain your answer? Please help! I don't understand what exactly the answer should include. Is the question referring to the direction of force? Or the relationship between the magnetic field and the current? Or something else entirely? Really appreciate any help!!

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
