The index of refraction of diamond is 2.4and the speed of light in vacuum is 300,000,000m/s. Calculate the speed of light in diamond. ​

The metric unit of electrical power is the watt volt ampere ohm

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.

The energy equivalent of the rest mass of an electron is
