An LC circuit in an AM tuner, such as that in a car radio, consists of a 2.2-mH inductor and a variable capacitor. The oscillation frequency of the circuit needs to be adjustable over the AM broadcast band from 540 to 1600 kHz. Required:
What range of capacitance (in pF) is required?

Argon is adiabatically compressed from an initial volume of 16 liters to a final volume of 2 liters. by what factor do the following quantities change? do they increase or decrease? (a) the rms speed (b) the thermal energy of the gas (c) the molar specific heat cv (d) the pressure

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.

Does current flow through or across a resistor?
