Answer : The pressure of the liquid at depth of 48 ft below the surface of fluid is, 21 psi.
Explanation : Given,
The pressure of the liquid at depth 8 ft = 3.5 psi
Now we have to calculate the pressure of the liquid at depth 28 ft.
According to the question,
As, the depth of 8 ft below the surface of a stagnant fluid has pressure = 3.5 psi
So, the depth of 48 ft below the surface of a stagnant fluid has pressure = 
Therefore, the pressure of the liquid at depth of 48 ft below the surface of fluid is, 21 psi.
Answer: 0.86g/mL
Explanation:
Mass of empty cylinder = 23.731g
Mass of cylinder + liquid = 26.414g
Mass of the liquid = 26.414 — 23.731
= 2.683g
Volume of the liquid = 3.12mL
Density = Mass / volume
Density = 2.683g / 3.12mL
Density = 0.86g/mL
The electrostatic potential is the work done to remove the charge. The molecule showing the potential map shows that it is HI.
<h3>What is electronegativity?</h3>
Electronegativity is the elemental property to attract the electron toward the atom and is affected by atomic number and the atomic radius. The map shows that the molecule is made of two different atoms and has linear geometry.
Due to the linear geometry, the molecule cannot be Br₂ and SO₃ as they are nonpolar and nonlinear respectively. Similarly, BrF and ICl can be eliminated as they are interhalogen compounds. In the HI molecule, the hydrogen atom is a cation and the iodine atom is an anion that has high electronegativity differences.
Therefore, HI is the molecule depicted in the potential map.

The molarity of the solution made by dissolving 0.05 mole of HCl in 2 L of H₂O is 0.025 M
<h3>What is molarity? </h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>How to determine the molarity </h3>
- Mole of HCl = 0.05 mole
- Volume = 2 L
- Molarity =?
Molarity = mole / Volume
Molarity = 0.05 / 2
Molarity = 0.025 M
Thus, the molarity of the solution is 0.025 M
