Physics

Which of the following is the most precise measurement?


ANSWER

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


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. $$3$$
