A student swings a container of water in a vertical circle of radius 1.0 m. Calculate the minimum speed of the container so that the water remains in the container at the top of the circle. ANS. 3.1 m/s E-4, P-12?

Why there is no inductive reactance in dc circuits

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.

If frequency goes up, what happens to wavelength? does it get shorter or longer?
