Vedclass · Answer

(A) $1$. Curie is a unit of radioactivity,defined as the number of disintegrations per second. Its dimension is $[T^{-1}]$,which corresponds to $(G)$.$2$. Light year is a unit of distance. Its dimension is $[L]$,which corresponds to $(H)$.$3$. Dielectric strength is the maximum electric field a material can withstand. Electric field $E = F/q$. Dimension: $[MLT^{-2}] / [IT] = [MLT^{-3}I^{-1}]$,which corresponds to $(I)$.$4$. Atomic weight is a dimensionless ratio of masses. Its dimension is $[M^0L^0T^0]$,but since it represents mass,it is often associated with $[M]$ in specific contexts,which corresponds to $(B)$.$5$. Decibel is a logarithmic unit used to express the ratio of two values of a physical quantity,such as power or intensity. It is dimensionless,which corresponds to $(C)$.Thus,the correct match is $(i)-G, (ii)-H, (iii)-I, (iv)-B, (v)-C$.
