Question

4. The______
exert maximum pressure at the bottom.​

Answer 1

The pressure exerted by a liquid is due to the combined weight of the liquid and atmosphere above it. While it is true that fluids exert pressure equally in all directions, this is a micro view of the situation. On a larger scale, the pressure varies with altitude. So an airliner needs a pressurized cabin, and pressures in the deep ocean require extremely strong-hulled submersibles for exploration.
