An LC circuit in an AM tuner (in a car stereo) uses a coil with an inductance of 9.9 mH and a variable capacitor. If the natural frequency of the circuit is to be adjustable over the range 540 to 1,600 kHz (the AM broadcast band), what range of capacitance (in pF) is required? smaller value
larger value

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

How can you improve the percent yield of copper in this lab? check all possible strategies that will you do so. measure reactants precisely. stir to the reaction take place. chill the reactants before combining them. wait patiently until the reaction completes. make sure to recover as much copper as possible.
