Question

A dam has ______ walls at the base than at the top.

Answer 1

1. The ratio of force to the area is called pressure.
2. $Pressure=\frac{Force}{Area}$
3. Pressure is inversely proportional to the area of the object.
4. A dam has broader walls at the bottom and narrower ones at the top.
5. Broader walls have more surface area hence it exerts less pressure on the land.

Hence, a dam has broader walls at the base than at the top.
