linear equations in one variable

By the study of electronic configuration of transition metals it is understood that variable oxidation state can be formed as there are both ns and (n-1)d electrons in bonding. The participation of ns electrons in bonding leads to +2 oxidation state which is a lower oxidation s..

Consider the same situation as in the above section. Let the particle move from P to P 1 with velocity v in time dt. Let d q be very small. We know th..

If one angle of a linear pair is acute, then what is the other angle? => Acute Angle or Obtuse Angle or Right Angle or None of the above..

Assume a rod of material having a length L o at initial temperature T o . When the temperature changes by D T, the length changes by D L. Experiment shows that if D T is not too large (say, less than 100 o C or so), D L is directly proportional to D T. If two rods made of the same material have the..

Let the length of the rod increase to 'l 2 ' . Increase in length = (l 2 -l 1 ) = l Rise in temperature = (t 2 -t 1 ) 0 c = t. The ratio of increase in length to its original length per every degree rise in temperature is known as ' the coefficient of linear exp..

Quantities such as height, weight, age, amount can have several different values. Quantities which can assume different numerical values are called variables. Variables are of two types: (a) Continuous (b) Discre..

A set of observations is called a called a collection of data. These observations should possess some common characteristics. They are recorded and used for further study. The quantities such as age, height and number of students are called variables..

Let S be a sample space associated with a given random experiment. A real valued function X which assigns to each w i S, a unique real number...

Which of the following linear systems matches with the linear system in the graph? => 3 y = -2, y = 1 or 3 y = 2 x , y = - x - 1 or 3 y = 2 x , y = x - 1 or None of the above..
