Answer:
-1, 0 and 1
Explanation:
The magnetic quantum number gives the number of possible spatial orientations or degeneracy of the orbitals in the subshells.
The number of possible spatial orientation is limited by the azimuthal quantum number.
For each value of azimuthal quantum number, there is a set of magnetic quantum number.
In the quantum number 4p;
the azimuthal quantum number = 1
The degeneracy becomes; -1, 0, 1

Force must be applied to initiate motion
for an object in:
A.all of the above
B.earth's atmosphere
C.outer space
D.the ocean
Answers
Force must be applied to initiate the motion of an object on earth's atmosphere, outer space and the ocean.
According to Newton's second law of motion, the force applied to an object is directly proportional to the product of force and acceleration of the object. The object tends to move in the direction of the applied force.
The formula for this law is written as follows;
F = ma = mg
where;
m is the mass of the objectg is acceleration due to gravity
Due to influence of acceleration due to gravity on objects, a force must be applied to initiate the motion of object located within the places where gravity is felt.

Kylie places a cube of metal A and a cube of metal B in two separate beakers of water. Then she heats the beakers. She keeps the mass of metal, the amount of water, and the amount of heat the same. At the end of her experiment, she finds that metal A has a lower temperature than metal B. What can she conclude about the thermal properties of the two metals?
Metal B is a better conductor than metal A.
Metal A is a better conductor than metal B.
Metal A has a higher heat capacity than metal B.
Metal B has a higher heat capacity than metal A.
Answers
Answer:
Metal A has a higher heat capacity than Metal B.
Explanation:
To answer this question, we have to think about what happened and what we know about thermal properties of metals. We are talking about temperature and heat in this question, so we can already eliminate both answers that talk about the metals being a conductor, because conductivity is related to electricity. That's not what the question asks. So therefore, we know one metal must have a higher heat capacity than the other. Heat capacity is defined as the number of heat units needed to raise temperature by one degree. If metal A has a lower temperature than metal B, it must have a higher heat capacity, because it takes more heat to raise the temperature. This is because metal B has a higher temperature than metal A. Therefore, the correct answer is Metal A has a higher heat capacity than Metal B.
How is Osmosis related to diffusion?
Answers
GREETINGS!
Diffusion is a process in which gases or liquid move from higher concentration to lower concentration
Osmosis is a process of movement of water molecules from higher concentration to the lower concentration through semi permeable membrane
SIMILLARITIES OF DIFFUSION AND OSMOSIS
Diffusion and osmosis both are the processes in which molecules move from high concentration to the lower concentration, also they do not require any energy so they both are passive transport examples.
The only dissimilarity is that in osmosis there is semipermeable membrane which Checks the movement of the water molecules ONLY

Answers
Answer:
1) The evidence that the universe is expanding can be explained by the observed redshifted light from distant galaxies which according to the evaluation means that the galaxies are in recession. The observation was explained by Hubble's law which stated that the rate of recession of the galaxies from the Earth is proportional to their away distance
2) The Big Bang Theory is a theory that scientists used to explain the origin of the universe. According to the big bang theory states that the universe started from an extremely high temperature and high density singular state that exploded and expanded over time to the the present day universe
3) Another evidence that supports the Big Bang Theory is the cosmic background radiation which is has its origin from the Big Bang
Explanation:
A student heats a test tube containing a large amount of protein and biuret reagent. She notices a color change from violet to blue. Explain why heating causes a color change
Answers
Answer:
Explanation:
Proteins are formed from amino acids that are held together by peptides bonds. We have excess of protein present with Biuret reagent which is a combination of sodium hydroxide(NaOH) and copper sulfate(CuSO4)
The normal color of biuret reagent is blue but when we have protein present in biuret reagent its color will be Violet and when we heat this the protein present in it will gain molecular energy disrupting the peptides bonds present as a result the color changes now to blue which is the original color of the biuret solution this happened because biuret test was used to detect proteins or peptide bond specifically but now they are disrupted hence the color change.

ice is melting at 0 degrees Celsius. Explain how the temperature of the melting ice stays the same while the thermal energy increases.
Answers
Because the heat applied to the ice is used to create the state transition rather than raising the temperature of the ice, the temperature stays constant while the ice is melting.
What is temperature ?The physical concept of temperature indicates in numerical form how hot or cold something is. A thermometer is used to determine temperature. Thermometers are calibrated using several temperature scales, which traditionally drew on different reference locations.
When ice melts, it absorbs the energy necessary to raise an equivalent mass of water by 80 degrees Celsius. As the material melts, the temperature stays steady at 0 C.
In contrast to water, which will not change phase at 0°C, ice will experience a phase transition at this temperature, requiring greater energy.
Thus, the temperature stays constant while the ice is melting.

As the temperature of a given sample of a gas decreases at constant pressure, the volume of the gas
Answers
As the temperature of a given sample of an ideal gas decreases at constant pressure, the volume of the gas: increases in accordance with Charles's law.
Charles law states that when the pressure of an ideal gas is kept constant, the volume of the gas is indirectly proportional to the absolute temperature of the gas.
Mathematically, Charles law is given by the formula;
[tex]\frac{V}{T} =k[/tex]
Where;
T is the temperature of an ideal gas.V is the volume of an ideal gas.According to Charles's law, when the volume of an ideal gas is decreased at a constant pressure, the temperature of the gas is increased and when the volume of a gas is increased at a constant pressure, the temperature of the gas is decreased due of the inverse relationship existing between them.
In conclusion, the temperature of a gas decreases the volume occupied by a gas provided pressure is kept constant in accordance with Charles's law.

What is the mass percent of a sugar solution having 15 g sugar dissolved in 63 g of solution?
Answers
Answer:
23.81%
Explanation:
The mass percent of a solution, also known as percentage by weight or w/w%, can be calculated using the formula:
mass percent = (mass of solute / mass of solution) x 100%
In this question;
Mass of solute (sugar) = 15g
Mass of solution (sugar + water) = 63g
Hence,
w/w% = 15/63 × 100
w/w% = 0.2381 × 100
w/w% = 23.81%
Therefore, the mass percent of the sugar solution is 23.81%.

Write the hyphen notation for the element that contains 15 electrons and 15 neutrons. 1. Copper-60 2. Oxygen-15 3. Phosphorus-30 4. Sulfur-31 5. Silicon-30 6. Zinc-60 7. Phosphorus-31 8. Fluorine-15
Answers
Answer:
Phosphorus-30
Explanation:
In hyphen notation, the mass number is written after the name of the element. An element that has 15 electrons and 15 neutrons would also contain 15 protons. Since the mass number of an element is the sum of the protons and neutrons in an atom of that element, the mass number of this element is 30.
Also, the number of protons (or electrons for a neutral atom) present in an atom of that element is known as the atomic number of that element.
In the periodic table of elements, the element with atomic number 15 is phosphorus. Thus, phosphorus has 15 protons, 15 electrons and 15 neutrons. Its mass number = 30. In hyphen notation, it is written as: Phosphorus-30
