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 1.1 hz oscillator with a 1.0 f capacitor. you have a spool of 0.25-mm-diameter wire and a 4.0-cm-diameter plastic cylinder.

how long must your inductor be if you wrap it with 2 layers of closely spaced turns?

What properties of a moving object are used in determining the object's energy of motion

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
