A.) dwarf
B.) supernova
C.) black hole
D.) giant
As a star uses up its hydrogen supply, it changes from the main sequence star to a Giant. Thus, the correct option for this question is D.
What is a Star?A star may be defined as a type of huge celestial body that is generally constructed of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. They are the luminous bodies that are visible in the sky at night.
A giant is a type of star that has utilized its hydrogen supply in its cores and transformed itself into the thermonuclear fusion of hydrogen in the shell that envelops its surroundings.
This creates an outwards force and stimulates fusion that initiates to increase and hence the star can not able to maintain its equilibrium longer.
Therefore, as a star uses up its hydrogen supply, it changes from the main sequence star to a Giant. Thus, the correct option for this question is D.

This element has three fewer protons than oganesson 
Answer:
ununpentium
Explanation: this is element 115, Oganesson has 118
The atomic number of oganesson is 118. The element which is having three fewer protons than oganesson is moscovium (Mc) (115).
What is oganesson?
Oganesson is a newly found element synthesized in 2002 and is placed as 118'th element in the periodic table. In modern periodic table, the elements are arranged based on their atomic number.
Atomic number is the number of protons in the atom as well it is the number of electrons in the neutral atom. For a neutral atom the number of electrons are protons are equal.
Thus in a neutral atom the positive charges are neutralized by equal number of negative charges.
Thus, for 118'th element, there are 118 protons, three fewer from this means, there are 115 protons, the 115'th element in the modern periodic table is moscovium.

A researcher is measuring changes in the density of the upper atmosphere over time. Which units should be used for the density measurements?
Answer:
lbm/ft³ or psi/ft
Explanation:
The description in the question shows the density to measured is that of gases (upper atmosphere). The density of a gas can be described as the mass of the gas divided by the volume of the gas at a certain temperature and pressure. It's unit can be represented as lbm/ft³ or psi/ft.
NOTE:
"lbm" means "lean body mass" which is a unit for mass or weight and can be described as the pound mass
"psi" means "pound per square inch"; is also a unit for mass or weight

Why will a toy train remain still if you push on the engine with
A force of 3 N and your friend push on the caboose with a
Force of 3 N?
Explanation:
Because when two equal forces are applied from opposite directions, they "eliminate" each other.
The train would go right if a 3N force was only applied in the right direction, and it would go left if the same force was only applied to the left.
If a 3N force was applied to the right and a 2N force to the left, it would equal a 1N force to the right (3-2=1).
But there it's 3-3=0, so in practice the force is 0N. Therefore the train won't move.

What are the units for Rf values? Please help!
Answer:
Microwatts.
Explanation:
RF + EMF Unit Conversion Charts: Interpreting exposure levels. When measuring Radio Frequencies, the most common units of measurement are microwatts per square meter (µW/m2), microwatts per square centimeter (µW/cm2) and volts per meter (V/m).
Answer:
No units
Explanation:
In Thin Layer Chromatography (TLC), retention factor (Rf value) is found by taking the distance travelled by the spot divided by the distance of the solvent front. Rf value is a ratio of distances hence they have no units.
Mathematical derivation
The distance travelled by the spot is in cm, and that of the solvent front is also in cm. Thus, dividing the two units would give us no units for the Rf value.
What is TLC?
TLC is a technique used for separation and identification. The stationary phase is polar while the solvent is relatively nonpolar. Thus, the less polar substance is more attracted to the solvent (according to the principle of 'like attracts like') and travels further and thus have a higher Rf value.

how many grams in 5mg
Answer:
0.005
Explanation:
I looked it up
Explanation: It's important to understand that "mg" is the abbreviation
for milligrams and "g" is the abbreviation for grams.
To convert 5 milligrams into grams, we first find the conversion factor
for milligrams and grams, which is 1,000 milligrams = 1 gram.
Next, notice that we're going from a smaller unit,
milligrams, to a larger unit, grams, so we divide.
Whenever we go from a smaller unit to a larger unit,
we will divide by the conversion factor.
So we have 5 mg ÷ 1,000.
When dividing by a power of 10, we can count the number of zeroes
in the power of 10 and move the decimal point that many places to the left.
So our answer is 0.005 grams.
Describe how the charges of the subatomic particles interact with one another.
Answer:
Electrons, Protons, and Neutrons. ... Protons are another type of subatomic particle found in atoms. They have a positive charge so they are attracted to negative objects and repelled from positive objects. Again, this means that protons repel each other
4. What is the proper way to prepare an acid solution?
Answer:
Always add acid to a large volume of water. The solution may then be diluted with additional water to make one liter. You'll get an incorrect concentration if you add 1 liter of water to the acid.
An acid is concentrated solution hence, it should be added to considerable quantity of water. The required volume can then be adjusted by adding more water.
What are the properties of an acid?Acids form aqueous solution and have the property of electric conductivity. Acids reacts with other molecules by forming a covalent bond.
Acids are corrosive in nature, sticky to touch, tastes sour and have strong smell.
Acids can be qualitatively detected through litmus test. They turn blue litmus paper red. Their pH is < 7 on pH scale.
Acids can be classified as:
Strong acids - are the acids that dissociate in water completely.Weak acids - are the acids that partially dissociate in water.Chemically, acids can react with other metals, carbonates and bases. Common examples of acids are vinegar (acetic acid), hydrochloric acid (HCl), sulfuric acid (H2SO4) etc.
Acids are found in food items such as citrus fruits. Acetic acid is widely used in certain food preparations and as food preservative. Acids are commercially used in dyes, paints and in soft drinks.
Thus, acids are important in many chemical reactions.

which best represents a particle containing 28 protons, 26 electrons,and 34 neutrons?
Answer:
This question lacks options, but the question can be answered based on knowledge of proton, electron and neutron number. The answer is:
62 Ni2+ particle
Explanation:
Nickel is a chemical element with atomic number 28. This means it has 28 electrons and 28 protons in its neutral atom. However, the isotope of nickel being described in the question has a mass number of 62. The mass number is calculated by adding the proton number with the neutron number. That is;
Mass number = number of protons + number of neutrons
Mass number = 28 + 34
Mass no. = 62
An element with mass number 62, which has lost two electrons to become positively charged (two positive charges) is described in the question. Hence, the particle that best fits this description is positively charged Nickel particle (Ni2+).
Ni2+ has 28 protons, 26 electrons (reduced by 2) and 34 electrons.
Note that, the 2+ charge is as a result of the loss of two electrons, hence, reducing the electron number by 2.
