Answer 1

Answer:

[ A ] = L , [ W ] = $T^{-1}$ , [ K ] = $L^{-1}$ , ∅ = No dimension

Explanation:

Trigonometric functions are dimensionless i.e

• W t is dimensionless
• K x is dimensionless
• ∅ is dimensionless

[ y ] = [ L ]

[ A ] = [ L ]

In terms of dimension :

1. [ W ] [ T ] = 1

   [ W ] = $T^{-1}$

2. [ K ] [ L ] = 1

    [ K ] = $L^{-1}$

3.  ∅ = 1  (∅ is dimensionless)
