In recent years it has been possible to buy a 1.0 f capacitor. this is an enormously large amount of capacitance. suppose you want to build a 1.0 hz oscillator with a 1.0 f capacitor. you have a spool of 0.25-mm-diameter wire and a 3.6-cm-diameter plastic cylinder. how long must your inductor be if you wrap it with 2 layers of closely spaced turns? express your answer to two significant figures and include the appropriate units.

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you
