A gyre is a set of currents that form:a. a line
b. a loop
c. weather
d. climate zones

Answers

A gyre is a set of currents that form b. a loop. The circulation of gyres are affected by global wind patterns, landmasses, and the planet's rotation. The circulation is also affected by temperature, as warm water goes up and cold water sinks. There are five major gyres in the world: North Atlantic, South Atlantic, Indian, North Pacific, and South Pacific.

Answer:

The answer is B. a loop hopefully this helps!

Please help me!!!!!!!What role does voltage play in the formation or use of an electromagnet?

Answers

The voltage drives the necessary force for an electromagnet to work. The strength of an electromagnet depends on the electric current which flows through its wires, but not on what drives the current. 

When two electron in a chemical bond are equally shared between two different atoms, what is the bond

Answers

When two electron in a chemical bond are equally shared between two different atoms, the bond is covalent bond.

What is covalent bond?

A chemical bond known as a covalent bond includes the exchanging of electrons between atoms to create electron pairs.

These electron couples are referred to as bonding pairs or sharing pairs. Covalent bonding is the stable equilibrium of attracting and repulsive forces that exists when two atoms share an electron.

The ability of each atom to reach the equivalent of a full valence shell, which corresponds to a stable electronic state, is made possible for many molecules by the sharing of electrons. Hence, when two electron in a chemical bond are equally shared between two different atoms, the bond is covalent bond.

Which of the following materials allows charges to flow easily?A. wood
B. an electrical conductor
C. glass
D. an electrical insulator

Answers

Answer: Option (B) is the correct answer.

Explanation:

A conductor which allows the quick or easy movement of charges through it is known an electrical conductor.

For example, copper is a good conductor of heat and electricity.

Whereas wood is a non-conductive substance as it does not allow the movement of charges through it. Thus, wood is a non-conductive in nature.

Glass is a poor conductor of electricity as it inhibits the flow of free movement of electrons through it.

Insulators are the substances or material in which there is also no movement of electric charges or very little movement of electric charges.

Thus, we can conclude that out of the given options, an electrical conductor allows charges to flow easily.
the correct answer is b

What is the bond between Hydrogen and Chlorine?

Answers

polar covalent bond
Hydrogen chloride is a diatomic molecule, consisting of a hydrogen atom H and a chlorine atom Cl connected by a polar covalent bond. The chlorine atom is much more electronegative than the hydrogen atom, which makes this bond polar.
covalent bond
chlorine and hydrogen atoms form a single covalent bond. in hydrogen chloride gas because the electrons are shared, not transferred from one atom to another. when it is dissolved in water to become hydrochloric acid.

Part C Next, you’ll test the hardness of each rock by scratching it with different substances as shown in the chart. The values in the chart are based on the Mohs Scale of hardness, which ranks the hardness of rocks and minerals on a scale of 1 to 10. First try to scratch a rock with your fingernail. If you can make a mark on the rock with your fingernail, record the related hardness value from the chart in your table. If a fingernail doesn’t scratch the rock, try to scratch it with the copper penny. If the penny doesn’t scratch the rock, try the wire nail and finally the masonry nail. Enter a hardness value for each rock.
