unit conversion practice

Another unit of force by which the magnitude of force can be understood and gauged, is the gravitational unit of force. A gravitational unit of force is that force with which the Earth attracts a body of unit mass towards its centre. A gravitational unit..

Commercial Unit of Electrical Energy - The unit 'watt' is very small. Therefore, in actual practice we use a much larger unit called 'kilowatt'. It is equal to 1000 watts. Since electrical energy is the product of power and time, watt hour (W h) can also be c..

Relation Between Atomic Mass Unit and MeV (Mass Energy Relation) - The unit in which atomic and nuclear masses are measured is called atomic mass unit (a.m.u). 1 a.m.u is defined as 1/12 t h of the mass of an atom of 6 C 1 2 isotope. It can be shown that 1 a.m.u = 1.66..

The Cell - The cell is the fundamental structural and functional unit of living organisms. Cells need energy for active transport, to move molecules between the environment and the cells across cells or within cells. Cells obtain energy by oxidation of molecules like glucose. This oxidati..

In the description of Angiosperms, family is the most useful taxonomic unit. Ranks higher than family are not of much practical significance and are used mostly in classification systems and academic discussions. The taxonomic category genus also does not get much importan..

Solar cells are expensive and are used only when supplying electricity becomes difficult. Solar cells are the devices where solar energy is directly converted into electricity. Solar cells are used in spacecrafts, radios, television, refrigerators, buoys and other navigation aid. Solar Cell Sunligh..
