Back Up Your Files on the Z: Drive Every teacher has file storage space reserved on a Proviso server for use as a backup location. It is called the Z: Drive. To locate your Z: Drive, open the My Computer icon on your desktop. If you do not see the icon on your desktop, click the Start button and find it in the menu. Under Network Drives, find the drive icon with your login name followed by your server name. There will be a (Z:) at the end of the login/server name.
Drawbacks-Higher tier. At the moment, superconductors only work at very low temperatures. They have to be kept very cold with liquid nitrogen or liquid helium. A lot of work is going into developing superconductors that will work at normal temperatures.Until this happens, their uses will be limited. Page: 1  1.hey will have little or no electrical resistance. For example, mercury is a liquid metal. It solidifies at â38.8 Â°C and becomes a superconductor at â268.8 Â°C.
Superconductivity is the ability of certain materials to conduct electric current with practically zero resistance. This produces interesting and potentially useful effects.For a material to behave as a superconductor, low temperatures are required.Superconductivity was first observed in 1911 by H. K. Onnes, a Dutch physicist. His experiment was conducted with elemental mercury at 4 degrees kelvin (approximately -452 degrees Fahrenheit), the temperature of liquid helium.his produces interesting and potentially useful effects.
