| 2. How do you determine the number of significant figures in a measurement for JEE? | |
Ans. To determine the number of significant figures in a measurement for JEE, count all the digits from the first non-zero digit on the left to the last digit on the right, including zeros that are in between non-zero digits or zeros that are at the end of a number and to the right of the decimal point.
| 3. Why are significant figures important in JEE exams? | |
Ans. Significant figures are important in JEE exams because they help convey the precision of a measurement. They indicate the level of uncertainty in a measured quantity and are crucial for correctly representing the accuracy of experimental results.
| 4. How do you perform calculations involving significant figures in JEE? | |
