Hi brainly users,

Here is your today's question :-

If surface tension of film (T) depends upon Energy (E), Velocity (V) and Time (t). Establish the formulae. ​

Answer 1

Heya!!

the formula for surface tension via these physical quantity will be-

Answer:Surface tension = EV^-2T^-2

S=F/L - (1)

E=F×D

F=E/D - (2)

From (1) & (2)

S=E/D×L - (3)

L=VT - (4)

From (3) & (4)

S=E/VT×D - (5)

S=E/VT×VT

S=E/V^2T^2

S=EV^-2T^-2
