1. State the number of significant figures in each of the following: (i) 208.91 (ii) 0.00456 (iii) 453 (iv) 2.945 x 10 4 (v) 0.3..

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 proportional to the accuracy of measurement. Eg...

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..

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..

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 accurac..

Arithmetic Operations With Significant Figures - The accuracy of a result is taken to be equal to the least accurate among the numbers, when 2 or more numbers are used to add, subtract, multiply or divide. The number of significant figures in the result, is e..

Introduction - 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. Suppose a measurement is recorded as 0.6204 cm. It means that the measurement was made correct to the ne..
