Vedclass · Answer

(A) Accuracy in a measurement is determined by the number of significant figures. $A$ higher number of significant figures indicates a more precise and accurate measurement.$A$. $400 	imes 10^{-4} \,m = 0.0400 \,m$ (Significant figures: $3$)$B$. $0.04 \,m$ (Significant figures: $1$)$C$. $40 \,m$ (Significant figures: $2$)$D$. $4 	imes 10^1 \,m = 40 \,m$ (Significant figures: $1$)Comparing the significant figures: $3 > 2 > 1$. Therefore,the measurement $400 	imes 10^{-4} \,m$ has the highest number of significant figures,making it the most accurate.
