The major difference between solid and fluid is the molecules are well-packed in solid but free to move in fluid. As a consequence of such difference, which of the following statements are correct? (i) Stress is proportional to strain in solid but stress is proportional to rate of strain in fluid. (ii) Fluid can be used as a lubricating film to separate 2 solid surfaces from direct contact to reduce friction. (iii) The energy required to move a ship slowly is low but increases rapidly with speed. (A) (B) (i) and (ii) (i) and (iii) (ii) and (iii) All of the above
