five significant figures

Significant Figures - It is the expression of accuracy of a physical quantity. The value in digits, accurately known in a measurement plus one digit that is not certain, is called significant figures. Significant figures is directly propor..

Significant Figures - The reliability of a measurement is indicated by the number of digits used to represent it. To express it more accurately we express it with digits that are known with certainty. These are called as Significant figures. They contain all ..

These express the degree of accuracy of measurements. It is a statement which gives number of digits up to which we are sure about their accuracy. It gives the degree of accuracy or precision made with the instrument. In practical life we depend only on approximate measurements. We ignore small me..

Let us consider the following entries in a Students' Journal: (a) Weight of a calorimeter = 42 g (measuring instrument used is spring balance) The smallest reading the spring balance can record is 1g. There are 42 of 1 g units of measurement. Hence, there are two significant figuresh..

1) Used to assess foetal growth and detect abnormalities such as spina bifida etc. 2) Useful in diagnosing kidney stones, gall stones, cirrhosis, obstructions in intestine, oviducts, uterus etc. 3) To measure blood flow through the heart, arteries and veins based on a phenomenon known as Doppler E..

We use specific number of digits to denote an exact value of a number for required accuracy. The digits used for such a purpose are called significant figures. The difference between these two values is called the absolute error. Absolute Error = Original number - Ap..
