An oil tank has a base of area 2.5 m2 and is filled with oil to a depth of 1.2 m. The density of the
1 answer:
Answer:
D. F = 24000[N]
Explanation:
To be able to calculate the force we must first find the pressure at the bottom of the tank. By means of the following equation:
where:
Ro = density of the liquid = 800 [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = elevation = 1.2 [m]
Pressure is defined as the relationship between Force on the area.

To calculate the speed and velocity of the Ann`s we use the formula,
Here, d is distance and t is time and v if we take it with direction then it is called velocity and if we take it without the direction then it is called speed.
Given and
.
Substituting these values in above equation we get
As Ann walked towards south direction therefore, Ann`s velocity is 3 mi/h south and her speed is 3 mi/h .
