Evaluate these two sound waves and determine what property they have In common
Answers
Answer:
The same wavelength
Explanation:
The two sound waves shown in the diagram has the same wavelength as clearly shown.
- Wavelength of a wave is the distance between a complete wave cycle.
- It is the difference between successive train of troughs and crests.
- In the figure shown the amplitude, vertical displacement of the wave differs.
- But the wavelength of the waves are the same.

Answer:
0.85 mol/L.
Explanation:
- Molarity is defined as the no. of moles of solute dissolved in a liter of the solution.
M = (no. of moles of solute)/(Volume of the solution (L))
no. of moles of calcium phosphate = 2.125 mol.
Volume of the solution = 2.5 L.
∴ M of calcium phosphate = (2.125 mol)/(2.5 L) = 0.85 mol/L.

Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions. The hydrolysis of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) and phosphoric acid (Pi) releases energy (it is an exergonic reaction).

At standard pressure, a certain compound has a low boiling point and is insoluble in water. At STP, this compound most likely exists as nonpolar molecules. Hence, option C is correct.
What are nonpolar molecules?
A molecule in which the individual dipoles cancel each other & result in zero net dipole moment is called a non-polar molecule.
Nonpolar molecules make weak attractions between molecules called van der Waals forces and they are loosely bound with each other.
Therefore, nonpolar molecules can easily go to the atmosphere by breaking those weak bonds and having a boiling point low.
Hence, option C is correct.

Answer is (3) - nonpolar molecules.
Nonpolar molecules make weak attractions between molecules called van der Waals forces. Hence, they are looesly bound with each other. Therefore, nonpolar molecules can easily go to the atmosphere by breaking those weak bonds. Hence, the boiling point is low.
Since water is a polar solvent, nonpolar molecules do not soluble in water.

Answer : The volume of a diamond is,
Explanation : Given,
Density of a diamond = 3.52 g/ml
Mass of a diamond = 15.1 g
Formula used :
Now put all the given values in this formula, we get the volume of a diamond.
Conversion used :
Therefore, the volume of a diamond is,
Density of a Material
The density of a material is defined as the mass per unit volume
it formula is given as
For the given exercise the correct answer is 4.28 cm^3
Formula for Density
Density = Mass/Volume
and the unit is g/cm^3
Explanation:
Given data
Mass = 15.1 g
Density = 3.52 g/ml
Volume = ????
Hence the Volume is expressed as
Volume = 15.1 /3.52
Volume = 4.28 cm^3
therefore the Volume is 4.29 cm^3
