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 ..

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 the certain digits plus one doubtful digit..

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..

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 ..

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 equal to the number of significant digits in the l..

The number of significant figures depends on the instrument used and accuracy required. It is wrong to record diameter as 2 cm. It means the reading is approximated to the nearest 1 cm. If the exact reading is 2 cm then it should be recorded as ..
