Investigating the rigidly rotating disc of dust with constant specific charge, we find that it leads to an extreme Kerr–Newman black hole in the ultra–relativistic limit. A necessary and sufficient condition for a black hole limit is, that the electric potential in the co–rotating frame is constant on the disc. In that case certain other relations follow. These relations are reviewed

In Sect. 2, we give a brief review of geodesic equations and accretion process in thin disks around a general stationary axisymmetric space-time.

The sense of sight thus fulfils a basic principle of nature: maintaining the unity in a variety of perceptions and thus through this unity maintaining the diversity. As a result of the turning motion of the Rotating Discs, observers see a dynamic penetration of the light and dark rotating parts. This creates surprising, colourful light phenomena.

Salt becomes molten at a lower temperature than sand. To separate the components, a mixture of salt and sand is heated above 801C, yet below 1710C.

So first, use a magnet to attract the iron nails. We also know that salt dissolves in water, while sand does not. So add water to dissolve the salt and leave out the sand. Now, filter the sand out, and then heat the salt solution to get rid of the water. There you have it. 2. In nature most things exist as mixtures. False or True True.
