Concept:Hydrostatic pressure increases with depth. Torricelli’s law states that the exit velocity is v=2gh​, where h is the depth below the water surface. Greater depth gives higher pressure and faster flow. The horizontal distance water travels depends on both exit speed and the hole’s height from the ground.Explanation:The lowest hole experiences the highest pressure, so water exits with the greatest force — statement (a) is true.The highest hole has the least pressure, so force is smallest — (b) is false.Pressure varies with depth, so force is not equal — (c) is false.For horizontal distance: the lowest hole has the highest speed but is closest to the ground. This combination gives the maximum range — (d) is true.The highest hole has lower speed and is higher up, so its range is smaller — (e) is false.Different holes have different speeds and heights, so distances are not the same — (f) is false.Thus the correct pair is (a) and (d).Answer:B. (a) and (d)
