# Which of the following is the most precise measurement?

$3\times {10}^{-3}m$

##### SOLUTION
To express any number, we always represent it in scientific notation.
for example:- $\Rightarrow 3.5\times 10^2$
so, $0.003$ is express it in scientific notation.
$3.0 \times {10^{ - 3}}$
Hence,
option $A$ is correct answer.

Q3 Single Correct Hard
The viscosity of a gas depends on mass, the effective diameter and the mean speed of the molecules. At room temperature, for He, $\eta_{He}=2\times 10^{-5}$ $kg{m}^{-1}{s}^{-1}$ and for $CH_{4}$, $\eta _{CH_{4}}=1.1\times 10^{-5}kgm^{-1}s^{-1}$. The diameter of the He atom is $2.1\times 10^{-10}m$ . lf the diameter of  $CH_{4}$ is $n\times 10^{-10}m$, find $'n'$.
Given mean speed of the molecules of the gas $v\propto \sqrt{\frac{K_B T}{m}}$ , where $K_B$ is the boltzmann's constant , $T$ is temperature and m is the mass of the gas.
• A. $2.1$
• B. $4$
• C. $3.2$
• D. $3$
