Question

give a brief description about why bottom of dam are broad

Answer 1

The reason is that the pressure exerted by a liquid increases with its depth. Thus, as the depth increases, more and more pressure is exerted by water on the wall of the dam. A thicker wall is required to withstand greater pressure, therefore, the thickness of the dam increases towards the bottom.IF YOU LIKE PLZZ PLZZ MAKE IT A BRALIST ANSWER AND CLICK ON THANK YOU

Answer 2

to decrease the pressure...because we know that we can reduce pressure by increasing it's surface area. and also the pressure increases as the the depth increases. that's why the bottom of the dam are broad
