When experimental data are subtracted, such as \( 12.9 \text{ g} - 7.06 \text{ g} \), according to the rules of arithmetic operations with significant figures, the result should be reported to:

  1. A
    5.84 g
  2. B
    5.8 g
  3. C
    6 g
  4. D
    5.840 g
View Answer & Solution

Correct answer · Option B

5.8 g

Explanation

In subtraction or addition, the final result should retain as many decimal places as there are in the number with the least decimal places (\( 12.9 \text{ g} \) has 1 decimal place). Thus, \( 5.84 \text{ g} \) rounds off to \( 5.8 \text{ g} \).

According to the NCERT rounding-off rules, the numbers \( 3.745 \) and \( 3.735 \), when rounded off to three significant figures, become respectively:→A spherical surface area element \( dA = 0.25\text{ m}^2 \) at a distance \( r = 0.5\text{ m} \) from the center subtends a solid angle \( \Omega \). An arc of length \( ds = 0.2\text{ m} \) on a circle of the same radius \( r = 0.5\text{ m} \) subtends a plane angle \( \theta \). The ratio of the numerical value of \( \Omega \) (in steradians) to \( \theta \) (in radians) is:→As illustrated in Fig. 1.1(b), a solid angle \( d\Omega \) is defined as the ratio of intercepted area \( dA \) of a spherical surface to the square of its radius \( r^2 \). A flat circular disc of radius \( R \) is placed perpendicular to the axis at a distance \( d = \sqrt{3}R \) from an apex \( O \). The solid angle subtended by the disc at the apex \( O \) is:→A substance of mass \( 5.74\text{ g} \) occupies a volume of \( 1.2\text{ cm}^3 \). Keeping the significant figures in view, its density should be expressed as:→
