      (B) The average difference in water level between high tide and low tide at a place, is called tidal range
      (C) The movement of water caused by the action of tide, is called a tidal current
      (D) All of the above

    2. The significant wave height is defined is the average height of the

      (B) Bollard
      (C) Anchors
      (D) Capstan

      (B) Vibrations are subjected
      (C) Internal pressure is developed
      (D) All of the above

    6. Assertion A: Intervention of undulations in the sea bed reduces the depth of wave at the section.

    8. Assertion A: Basin walls have to be of much greater height than dock walls.
    Reason R: Tidal basins are subject to fluctuations of levels due to tidal variations
    Select your answer based on the coding system given below:
      (A) Both A and R is true and R is the correct explanation of A
      (B) Both A and R is true but R is not correct explanation of A
