If we give a peice of gold negative charge and shine long wave, low frequency, electro-magnetic (E-M) radiation on it (for example radio waves) absolutely nothing will happen.

If you star...

This is a question testing the knowledge of the equations of constant acceleration (Suvat equations)First convert the question into a standard form. For example by writing out the variables as follows s (...

Firstly we must figure out what we know about this particle. We have its stangeness which is 1 and we know its charge from the "+" symbol in the question, which is also 1.For the first bit we sh...

Current is the rate of flow of charge in a circuit; you can imagine the flow of electrons as water flowing through a pipe. If the pipe splits into two, some of the flow will go through one pipe and som...

To integrate ln(x) you will need to use intergration by parts. As you can differentiate ln(x) (it is equal to 1/x) and there is an implied 1xln(x). As a result you can differentiate ln(x) and integrate...
