Question

A dam for water reservoir is built thicker at the bottom than at the top because: (a) pressure of water is very large at the bottom due to its large depth (b) water is likely to have more density at the bottom due to its large depth (c) quantity of water at the bottom is large (d) none of the above

Answer 1

correct ans is option(a)
bcoz liquid pressure increases as the depth increases.
Hope ie helps u !!!!!

Answer 2

because as we go down in water pressure increases same as in oceans increase in depth causes increase in the pressure so the dam is made thick at the bottom because pressure at teh bottom of the dam is the greatest so to prevent the breakage of the dam it's made thick at the bottom,...I hope this helps you
