A. Many light waves traveling away from a source
O B. Two light waves traveling perpendicularly to a source
C. Several light waves circling a source
D. A single light wave traveling away from a source.
Answers
The model represents where electromagnetic radiation transmits energy should be option d. A single light wave traveling away from a source.
What is electromagnetic radiation?It is the energy that should be transmitted at the fixed velocity via the sinusoidally that varied from the electric and magnetic fields.
Here the frequency of variation of the energy should be presented by the Greek letter ν.
Hence, the option d is correct.

What describes the light as electromagnetic waves?Light as a wave: Light is a type of electromagnetic wave that can be represented mathematically (described). A shifting magnetic field is produced by a shifting electric field, according to this paradigm. Light is produced when the electric field changes as a result of the changing magnetic field.Light can be thought of as a wave. Light is a type of electromagnetic wave. A fluctuating electric field, according to this hypothesis, generates a fluctuating magnetic field. The interaction of a changing magnetic field with a changing electric field produces light. When charged particles, such as electrons and protons, move, they generate electromagnetic fields, which transport the type of energy known as electromagnetic radiation, or light.To Learn more About electromagnetic radiation, Refer:

Mass of Hydrogen = 3.7 g
Further explanationThe empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.

Answers
Answer:
The molecule has a bent geometry
Explanation:
Let us look again at the principles of VSEPR theory. The shape of a molecule depends on the number of electron pairs that surround the valence shell of the central atom in the molecule.
Lone pairs distort the molecular geometry away from what is expected on the basis of VSEPR theory.
The molecule described in the question has the form AEX2. Two substituents and one lone pair form three electron domains around the central atom. The expected geometry is trigonal planar but the observed molecular geometry is bent because of the lone pairs present.

B will give up two electrons to form bonds.
Both A and B will be chemically unreactive.
Both A and B will gain electrons to become stable.
Answers
Answer:
B will give up two electrons to form bonds.
Explanation:
B has 12 electrons, it means that the electronic configuration of B is; 1s2 2s2 2p6 3s2. The implication of this is that B must be an element of group 2 since it has an outermost electron configuration of ns2.
The elements of group 2 form ionic bonds by loss of two electrons. This implies that B will form bonds by loss of two electrons.
The statement i.e. correct is B will give up two electrons to form bonds.
The following information should be considered:
B has 12 electrons, it means that the electronic configuration of B is; 1s2 2s2 2p6 3s2. It represent that B must be an element of group 2 since it has an outermost electron configuration of ns2.

difference between fluids and nonfluids
Answers
Answer:
All liquids are fluids but not all fluids are liquids. Fluids basically describe anything that can flow as a result of a difference in pressure between two points. Liquids on the other hand are a subset of fluids. Liquids are the incompressible fluids. These are the fluids who's density does not change sharply with pressure.
Gases are also fluids, they form the compressible fluids. They do flow as a result of difference in pressure between two points but at the same time they can be compressed or expanded. Their density fluctuates with pressure.
Hence fluids consist of 2 mutually exclusive groups of compressible and incompressible fluids. Liquids are the incompressible fluids and hence form a subset of the more general term fluid.

Answers
Answer:
Bacteria
Explanation:
Some plants, specifically leguminous plants form a symbiotic relationship with certain bacteria species called NITROGEN-FIXING BACTERIA in their root nodules. In this relationship, the bacteria species e.g nitrosomonas, nitrobacter etc help the plants fix atmospheric nitrogen (N2) or ammonium compounds, which are forms of nitrogen that are unusable to the plant into nitrates, a usable form.
Therefore, BACTERIA are the organisms found around the roots of these set of plants (legumes) that turns nitrogen from the form we cannot use to the form we can use.

What type of reaction occurs when Carbon-14 changes to Carbon-12?
O Single Replacement
O Fusion
O Decomposision
O Fission
Answers
Answer: flood
Explanation:
The type of reaction that occurs when Carbon-14 changes to Carbon-12 is fission reaction. The correct option is D.
What is nuclear fission?Nuclear fission is the operation by which an atom's nucleus splits into two or several smaller nuclei.
Even by radioactive decay's energetic standards, the fission process frequently produces gamma photons and releases a large amount of energy.
Nuclear energy can be used to generate electricity, but it must be liberated from the atom first. Atoms are split to release energy during the nuclear fission process.
The decay of carbon-14 is another nuclear reaction that we can use. Carbon is a necessary element for living organisms that constantly exchange carbon, the majority of which is carbon-12.
However, some of those carbon atoms are carbon-14 isotopes.
Thus, the correct option is D.
