Practice question

Given: What is the SI unit of a quantity with dimensional formula [M L T^{-1] ? These values define the system as per NCERT data. Formula: [M] = kg, [L] = m, [T] = s. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: [M L T^{-1] = kg m s^{-1 . (Matches momentum or impulse). Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
