Answer:
2354.4 Pa
40221 Pa
Explanation:
= Density = 1000 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
h = Depth
The pressure difference would be
![\Delta P=\rho gh\\\Rightarrow \Delta P=1000\times 0.24\times 9.81\\\Rightarrow \Delta P=2354.4\ Pa](https://tex.z-dn.net/?f=%5CDelta%20P%3D%5Crho%20gh%5C%5C%5CRightarrow%20%5CDelta%20P%3D1000%5Ctimes%200.24%5Ctimes%209.81%5C%5C%5CRightarrow%20%5CDelta%20P%3D2354.4%5C%20Pa)
The pressure difference in the first case is 2354.4 Pa
![\Delta P=\rho gh\\\Rightarrow \Delta P=1000\times 4.1\times 9.81\\\Rightarrow \Delta P=40221\ Pa](https://tex.z-dn.net/?f=%5CDelta%20P%3D%5Crho%20gh%5C%5C%5CRightarrow%20%5CDelta%20P%3D1000%5Ctimes%204.1%5Ctimes%209.81%5C%5C%5CRightarrow%20%5CDelta%20P%3D40221%5C%20Pa)
The pressure difference in the second case is 40221 Pa

true! : )
(i underlined the place where the answer is the other information is just as important but if you do not want to read it you do not have to)
Explanation:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases. the greater the mass, the greater the gravitational pull. <u>gravitational pull decreases with an increase in the distance between two objects.</u> Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
