Question

Imagine That the tank is filled with water. The height of the liquid Collin is 7 m and the area is 1.5 m² what’s the force of gravity acting on the column of water

Answer 1

== The volume of water in the tank is (1.5 m²) x (7 m) = 10.5 m³ .

== The density of water is 1000 kg / m³ .

== The mass of water in the tank is (10.5 m³) x (1000 kg/m³) = 10,500 kg.

== The force of gravity is (mass?) x (gravity)

force = (10,500 kg) x (9.8 m/s²)

force =  102,900 Newtons

Answer 2

Answer: 102,900 N

I remember this question from one of my, test. Really hope this helps..
