Question

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). What's the force of gravity acting on the column of water? A. 102,900 N B. 110,700 N C. 68,600 N D. 73,500 N

Answer 1

took the test on penn foster its A

Answer 2

Answer: The correct answer is option A.

Step-by-step explanation:

Height of the liquid column = 7 m

Area of the base = 1.5
`m^2`

`Pressure=(Force)/(Area)`

`Force=Pressure* Area=`

`Pressure=density* g* Height`

`P=1000 kg/m^3* 9.8 m/s^2* 7 m=68,600 kg/s^2m`

`F=68,600 kg/s^2m* 1.5 m^2=102,900 N`

Hence,the correct answer is option A.
