In the course of the experiment, the properties of the material of a some body were investigated , as a result of which the average density and its absolute error were obtained bar (rho )=0.663g/cm^3 Delta bar (rho )=0.01454ldots g/cm^3 Plea se select the correct record of the final result of this experiment. rho =(0.66300pm 0.01454)g/cm^3 rho =(1.0pm 0.1)g/cm^3

The correct record of the final result of this experiment is:<br /><br />$\rho =(0.66300\pm 0.01454)g/cm^{3}$<br /><br />This record correctly includes the average density of the material, $\bar{\rho} = 0.663g/cm^{3}$, and its absolute error, $\Delta \bar{\rho} = 0.01454g/cm^{3}$. The absolute error is represented with the correct number of significant figures, and the average density is given with the appropriate number of significant figures as well.
