fractional increase

The numerator of a fraction is 17 less than its denominator. If the numerator is doubled and the denominator is increased by 4, then the value of the resulting fraction is 2, choose an equation to find the fraction. Let x represents the denominator of the ..

The numerator of a fraction is 4 less than its denominator. If the numerator is doubled and the denominator is increased by 3, then the value of the resulting fraction is 3. Write an equation to find the fraction, if x represent the denominator of the fr..

A fraction becomes 1 2 , when its denominator is increased by 7, and 1 3 when its numerator is decreased by 9. Write an equation or inequation that will help you find the denominator. => 3( y + 27) = 2( y + 7) or y 2 + 7 = y 3 - 9 or 2( y + 27) = 2( y + 7) or y + 7 = y - 9..

On plotting a fraction of molecules having different speeds against the speeds of the molecules (along x-axis) a curve known as Maxwell's distribution curve is obtained. The important features of which are: The fraction of molecules with very low or very high speeds is very smal..

Petroleum is a mixture of hydrocarbons. On combustion, it produces mainly carbon dioxide and water vapour. However, on incomplete combustion, they produce carbon monoxide, unburnt hydrocarbons etc. They also produce oxides of nitrogen. Petrol is an important fraction of petroleum used in..

Production of aromatic hydrocarbons (arenes) like benzene, toluene and xylenes. Earlier the bulk of arenes were obtained from coal tar, but now they are derived from petroleum by the process of reforming. Increasing the octane number of straight-run gasoline by increasing t..

'. It is a process in which heavier oil fraction is treated with a suitable catalyst at an appropriate temperature. Here the molecules of heavier fractions break into that of lower hydrocarbons forming a volatile liquid. Cracking is needed to increase the yield of petr..

Energy Barrier - In this theory, the rate constant is related to three factors Z, f and p by the equation k = Zfp b (19) where Z is the collision frequency f is the fraction of collisions having energy greater than the threshold energy and p is the fraction of the collisions tha..

. This gives In the temperature range in which resistivity increases linearly with temperature, the temperature coefficient of resistivity a is defined as the fractional increase in resistivity per unit increase in temperature. Ohm's law is obeyed by many sub..

. We call it an equation of state even when we do not know the actual equation. Here's a simple (though approximate) equation of state for a solid material. The temperature coefficient of volume expansion b is the fractional volume change per unit temperature change, and the compressibili..
