Explanation
As surface tension and surface energy both have different SI unit and same dimensional formula.
As ω (angular velocity) has the dimension of [T–1] not [T].
Dimensional constant are the quantities whose values are constant and they posses dimensions. For example,velocity of light in vacuum, universal gravitational constant, Boltzman constant, Planck’s constant etc.
A.U. (Astronomical unit) is used to measure the average distance of the centre of the sun from the centre of the earth, while angstrom is used for very short distances. 1 A.U. = 1.5 × 1011 m; 1Å = 10–10 m
