1. \(1\)
2. \(2\)
3. \(3\)
4. \(4\)
In which of the following, the number of significant figures is different from that in the others?
1. \(2.303~\text{kg}\)
2. \(12.23~\text{m}\)
3. \(0.002\times10^{5}~\text{m}\)
4. \(2.001\times10^{-3}~\text{kg}\)
The mass and volume of a body are \(4.237~\text{grams}\) and \(2.5~\text{cm}^3\), respectively. The density of the material of the body in correct significant figures will be:
1. \(1.6048~\text{grams cm}^{-3}\)
2. \(1.69~\text{grams cm}^{-3}\)
3. \(1.7~\text{grams cm}^{-3}\)
4. \(1.695~\text{grams cm}^{-3}\)
The number of significant figures in \(0.0006032\) m2 is:
1. \(4 \)
2. \(5\)
3. \(7\)
4. \(3\)
What is the number of significant figures in \(0.310\times 10^{3}?\)
1. \(2\)
2. \(3\)
3. \(4\)
4. \(6\)
Each side of a cube is measured to be \(7.203~\text{m}\). What are the total surface area and the volume respectively of the cube to appropriate significant figures?
1. \(373.7~\text{m}^2\) and \(311.3~\text{m}^3\)
2. \(311.3~\text{m}^2\) and \(373.7~\text{m}^3\)
3. \(311.2992~\text{m}^2\) and \(373.7147~\text{m}^3\)
4. \(373.7147~\mathrm{m^2}\) and \(311.2992~\text{m}^3\)
If \(97.52\) is divided by \(2.54\), the correct result in terms of significant figures is:
1. | \( 38.4 \) | 2. | \(38.3937 \) |
3. | \( 38.394 \) | 4. | \(38.39\) |
The decimal equivalent of \(\frac{1}{20} \) up to three significant figures is:
1. | \(0.0500\) | 2. | \(0.05000\) |
3. | \(0.0050\) | 4. | \(5.0 \times 10^{-2}\) |
The numbers \(2.745\) and \(2.735\) on rounding off to \(3\) significant figures will give respectively,
1. \(2.75\) and \(2.74\)
2. \(2.74\) and \(2.73\)
3. \(2.75\) and \(2.73\)
4. \(2.74\) and \(2.74\)
1. | \(9.98\) m | 2. | \(9.980\) m |
3. | \(9.9\) m | 4. | \(9.9801\) m |
