Is a force created by the water that is displaced by an object.
Answers
Answer:
Buoyancy.
Explanation:
Buoyancy is a force created by the water that is displaced by an object. It is directly proportional to the amount of water that is being displaced by an object.
Hence, the greater the amount of water an object displaces; the greater is the force of buoyancy pushing the object up.
The buoyancy of an object is given by the formula;
Where;
Fb = buoyant force of a liquid acting on an object.
g = acceleration due to gravity.
p = density of the liquid.
v = volume of the liquid displaced.
h = height of liquid (water) displaced by an object.
A = surface area of the floating object.
The unit of measurement for the buoyancy of an object is Newton (N).

To calculate the molar mass of a compound, sum the atomic masses of all atoms in the compound. Ammonia has a molar mass of 17.04 g/mol, magnesium hydroxide has a molar mass of 58.33 g/mol, and iron(III) oxide has a molar mass of 159.70 g/mol.
Explanation:
Calculating Molar Mass
To calculate the molar mass of a compound, you sum the atomic masses of each individual element present in the compound, multiplied by the number of each of those atoms in the formula.
Ammonia (NH3): The atomic mass of nitrogen (N) is approximately 14.01 g/mol and hydrogen (H) is approximately 1.01 g/mol. Since ammonia contains one nitrogen atom and three hydrogen atoms, its molar mass would be (14.01 g/mol) + 3 × (1.01 g/mol) = 17.04 g/mol.
Magnesium hydroxide (Mg(OH)2): The atomic mass of magnesium (Mg) is approximately 24.31 g/mol, oxygen (O) is approximately 16.00 g/mol, and hydrogen (H) is again 1.01 g/mol. Magnesium hydroxide has one magnesium atom, two oxygen atoms, and two hydrogen atoms. Thus, its molar mass is (24.31 g/mol) + 2 × (16.00 g/mol) + 2 × (1.01 g/mol) = 58.33 g/mol.
Iron(III) oxide (Fe2O3): The atomic mass of iron (Fe) is approximately 55.85 g/mol and oxygen (O) is 16.00 g/mol. Iron(III) oxide consists of two iron atoms and three oxygen atoms, giving a molar mass of 2 × (55.85 g/mol) + 3 × (16.00 g/mol) = 159.70 g/mol.

B) markings on the casing
C) markings on the bullet
D) powder residues
Answers
One that is can associate a suspect and the firing of a gun is powder residues. The correct option is D.
What is gun power residue?
GSR is made up of unburned or partially burned gunpowder particles, soot, nitrates, and nitrites from powder combustion, primer particles (oxides of lead, antimony, and barium), and bullet or bullet jacket particles that are vaporized when a firearm is discharged.
Gunshotresidue (GSR) is a speck of vital trace evidence that assists forensic scientists in solving a wide range of firearm-related incidents.
The identification of the shooter, as well as bullet identification from a gunshot wound, aid in the reconstruction of a crime scene.
Powderresidues are one thing that can link a suspect to a gunshot.
Thus, the correct option is D.
