If a total force exerted by water in a container with a bottom area of 2 square meters is 450 newtons, what's the water pressure at the bottom of the container?

A) 0.300 kPa
B) 0.575 kPa
C) 0.900 kPa
D) 0.225 kPa

Answer :

The water pressure at the bottom of the container is found by dividing the force (450 newtons) by the area (2 square meters), which results in a pressure of 0.225 kPa. Hence the correct option would be option d.

The water pressure at the bottom of the container is calculated by dividing the total force exerted by the water by the area of the container's bottom. The force exerted by the water is given as 450 newtons, and the area is 2 square meters. Therefore, using the formula pressure = force / area, the pressure can be calculated as 450 N / 2 m2 = 225 N/m2. Since 1 pascal (Pa) is equal to 1 N/m2, and 1 kilopascal (kPa) is equal to 1000 Pa, the pressure in kilopascals is 0.225 kPa.
