Question 11 of 149

Match List I with List II. List I List II (A) Torque (I) Nms−1{Nms}^{-1} (B) Stress (II) Jkg−1{Jkg}^{-1} (C) Latent Heat (III) NmNm (D) Power (IV) Nm−2{Nm}^{-2} Choose the correct answer from the options given below:

Show answer and solution

Answer: (B) A−III,B−IV,C−II,D−IA-III,B-IV,C-II,D-I

Torque =Force×perpendicular distance(r⊥)=\text{Force}\times \text{perpendicular distance}\left({r}_{\perp }\right) NmNm Stress=ForceAreaStress=\dfrac{Force}{Area} Nm−2N{m}^{-2} Latent heat =EnergyMass=\dfrac{Energy}{Mass} Jkg−1J{kg}^{-1} Power =WorkTime=Force×displacementTime=\dfrac{Work}{Time}=\dfrac{Force\times displacement}{Time} Nms−1Nm{s}^{-1} Thus, the correct answer is A−III,B−IV,C−II,D−IA-III,B-IV,C-II,D-I.
