An AC power source with Vm = 220 V and f = 60.0 Hz is connected in a series RLC circuit. find the capacitive reactance and inductive reactance
The maximum wavelength for which an electomagnetic wave can eject electrons from a platinum surface is 196 nm. what is the maximum speed of the ejected electrons
A soap film formed in a loop of wire is, because of its weight, not exactly uniform in thickness, but wedge-shaped in cross section. When the film is illuminated with 546 nm light, one sees four interference fringes spread over a distance of 2.0 c..
solenoid is formed by winding 23.0 m of insulated silver (resistivity 1.59 x 10-8 Ω·m) wire around a hollow cylinder. The turns are wound as closely as possible without overlapping, and insulating coat on the wire is negligibly thin.
In the above problem, if the radius of the circular loop expands to 1.0m in 2 seconds, calculate the EMF and the direction of the current in the loop
