Vedclass · Answer

(A) Statement $(A)$ is correct: $A$ physical quantity can be measured in different units (e.g.,length can be measured in $m, cm, ft, inch$).Statement $(B)$ is correct: The dimensional formula of a physical quantity is unique,representing its fundamental nature.Statement $(C)$ is correct: Different physical quantities can share the same dimensions (e.g.,work and energy both have dimensions $[ML^2T^{-2}]$).Statement $(D)$ is correct: According to the principle of homogeneity of dimensions,only physical quantities with the same dimensions can be added or subtracted.Since all four statements are correct,the total number of correct statements is $4$.
