Relative error in an is n times the relative error a It can be proved that maximum relative error in X, Also, maximum percentage error in X, Maximum percentage error in X = l times maximum percentage error in a + m times maximum percentage error in b + n times maximum percentage error in c..

The electricity produced from flowing water is called Hydroelectric power. The world's first hydroelectric power plant was set up in 1882 in Wisconsin USA. It had a very small output, supplying power only for about 250 light bulbs. But from this small start the h..

Chemical energy stored in the coal is used to heat water producing steam which turns turbines rotating electromagnets, which in turn generates electricity. The majority of power stations in Britain use coal as their energy source. It is wrong to suppose that the coal industry is declining..

m B n is then expressed as, K s p = [A p + ( a q ) ] m + [ B q - ( a q ) ] n . Thus, the solubility product constant (K s p ) of a sparingly soluble salt is defined as the product of the molar concentrations of the ions in a saturated solution of the sparingly s..

Solubility product Ionic product It is the product of the concentration of ions of the electrolyte each raised to the power of their coefficients in the balanced chemical equation in a saturated solution It is the product of the c..

Introduction - Newton's laws of motion help us to analyse many kinds of motion. But the analysis is complicated, requiring details about the motion that we simply do not know. Long ago, people used to trade by only exchanging products when the concept of 'money' was yet to be introduced. ..

How many electrons flow through the filament of a 120 V, 60 W electric lamp in one second? Given: Electric power is the product of voltage and curren..

Waste products from nuclear power stations etc. are becoming a serious problem. They should be put where the radiation can do no harm. Unfortunately, there is no way of stopping a radioactive nucleus from emitting radiatio..
