1.	Which of the following pairs have different dimensions?A. `Frequency and angular velocity.B. Tension and surface tension.C. Density and energy density.D. Linearmomentum and angular momentum.
Answer» Correct Answer - B::C::D Frequency and angular velocity have the same dimension `[T^(-1)]`. Tension has dimensions of force and surface tension has dimensions of `"force"//"length"`. Density has dimensions of `"mass"//"volume"` and energy density has dimensions of `"energy"//"volume"`. Angular momentum has dimensions of linear momentum `xx` distance.
