Question

The dimensions of the quantities in one (or more) of the following pairs are the same. Identify the pair(s).

• A. Torque and work
• B. Angular momentum and work
• C. Energy and Young's modulus
• D. Light year and wavelength

Answer 1

Answer: (A), (D)

Torque and work
Light year and wavelength

Torque$=M^1{L}^2{T}^{-2}$

Work$=M^1{L}^2{T}^{-2}$

angular momentum(L)=$M^1{L}^2{T}^{-1}$

Energy$=M^1{L}^2{T}^{-2}$

Young's Modulus $\left(Y\right)$$=M^1{L}^2{T}^{-2}$

Light year$=L$

Wavelength$=L$
