Question

25. Define suriase energy. Prove that it is numerically equal to the surface tension
26. State and prove Work - Energy theorem.
27. Which of the following functions of time represent​

Answer 1

Answer:

A is the total increase is the surface area of the film. Therefore the surface energy and the surface tension are numerically equal

The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle. ... The kinetic energy of the block increases as a result by the amount of work.
