Answer 1

Answer:

This expression indicates that surface tension is equal to surface energy per unit area of the surface film. To Find: Work done = W =? Example – 2: A liquid film is formed in a rectangular frame one side of which is a light and thin movable wire of length 4 cm.

formula of surface energy:- , E = [M1 L2 T-2] × [M0 L2 T0]-1 = [M1 L0 T-2]. Therefore, the surface energy is dimensionally represented as [M1 L0 T-2].

Answer 2

Answer:

Or, E = [M1 L2 T-2] × [M0 L2 T0]-1 = [M1 L0 T-2]. Therefore, the surface energy is dimensionally represented as [M1 L0 T-2].
