An object of mass $m = 3.513 \ kg$ moves along the $x$-axis with a velocity of $5.00 \ ms^{-1}$. The magnitude of its momentum can be recorded as $...... \ kg \ ms^{-1}$.

The mass and volume of a body are $4.237 \ g$ and $2.5 \ cm^3$,respectively. The density of the material of the body in correct significant figures is $:-$ (in $g \ cm^{-3}$)

The radius of a thin wire is $0.16 \; mm$. The area of cross-section taking significant figures into consideration in square millimeters is?

From the point of view of significant figures,which of the following is/are correct?
$(i)\ 11.3 \ cm + 4 \ cm = 15.3 \ cm$
$(ii)\ 4.53 \ m - 1.2 \ m = 3.3 \ m$
$(iii)\ 5.45 \ kg - 3.2 \ kg = 2.25 \ kg$
$(iv)\ 84.8 \ cm + 48.6 \ cm = 133 \ cm$

The length of the side of a cube is $1.2 \times 10^{-2} \ m$. Its volume up to correct significant figures is

If a calculated value $2.7465 \,g$ contains only three significant figures,the two insignificant digits in it are ............
