Physics-Significant Figures
NEET Physics Significant Figures Match the Following Question
Type: Match the Following-match the column-Medium-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Density calculation | (i) 4 significant figures |
| (b) Surface area of a cube | (ii) 3.142 |
| (c) Rounding off 2.745 | (iii) 2.74 |
| (d) Measurement uncertainty | (iv) 1.688 g/cm³ |
A
a-iv, b-i, c-iii, d-ii
B
a-ii, b-i, c-iii, d-iv
C
a-iv, b-ii, c-iii, d-i
D
a-iii, b-i, c-ii, d-iv
Correct Answer
Option A
Detailed Explanation
The density calculation from 4.237 g and 2.51 cm³ gives 1.688 g/cm³. The surface area calculation of a cube with a side of 7.203 m is rounded to 4 significant figures as 311.3 m². Rounding off 2.745 to three significant figures gives 2.74. The value of π can be approximated as 3.142.
