Fill in the blanks:
$(a)$ $\frac{1\,\mu m}{1\,fm} = \,....$
$(b)$ The number of significant figures in $0.0060$ is $....$
$(c)$ To study nanotechnology,the $....$ microscope has been developed.
$(a)$ $\frac{1\,\mu m}{1\,fm} = \,....$
$(b)$ The number of significant figures in $0.0060$ is $....$
$(c)$ To study nanotechnology,the $....$ microscope has been developed.
(N/A) Since $1\,\mu m = 10^{-6}\,m$ and $1\,fm = 10^{-15}\,m$,then $\frac{10^{-6}}{10^{-15}} = 10^{9}$.
$(b)$ In the number $0.0060$,the leading zeros are not significant. The non-zero digit $6$ and the trailing zero after the decimal point are significant. Thus,there are $2$ significant figures.
$(c)$ The Scanning Tunneling Microscope $(STM)$ is used for the study of nanotechnology.

View SolutionTo determine the Young's modulus of a wire,the formula is $Y = \frac{FL}{A\Delta L}$,where $L$ is the length,$A$ is the area of cross-section of the wire,and $\Delta L$ is the change in length of the wire when stretched with a force $F$. The conversion factor to change the unit of Young's modulus from $CGS$ to $MKS$ system is $x \times 10^{-1} \ N/m^2$. Find the value of $x$.
