Weegy: Imagine that a tank is filled with water. The height of the liquid column is 7 meters and the area is 1.5 square meters (m2). The force of gravity acting on the column of water is 102,900 N.
Solution:
the volume of water is: (1.5m^2 x 7m) = 10.5 m^3;
10.5 m^3 = 10,500 liters;
water mass: (10,500 liters) x (1kg/liter) = 10,500 kg;
weight of the water: (10,500 kg) x (9.8 m/s^2) = 102,900 N.
