Neptune is significantly farther from the Sun than Mercury by a factor of millions, illustrating the vast scale of our solar system.

One Astronomical Unit (AU) is approximately equal to the average distance between the Earth and the Sun, which is about 93 million miles (or 149.6 million kilometers).

Given the average distances of Mercury and Neptune from the Sun:

1 AU = 93 million miles

For Mercury (0.4 AU):

Distance from the Sun = 0.4 AU × 93 million miles/AU = 37.2 million miles

For Neptune (30 AU):

Distance from the Sun = 30 AU × 93 million miles/AU

= 2,790 million miles (or 2.79 billion miles)

Comparing their average distances in miles from the Sun:

Mercury will be approximately 37.2 million miles from the Sun.

Neptune is approximately 2.79 billion miles from the Sun.

As you can see, Neptune is significantly farther from the Sun than Mercury by a factor of millions, illustrating the vast scale of our solar system.

Answer:

Helium

Explanation:

Answer:ok

Explanation:

Answer:

1. The goal of science is to explore and understand the physical world around us.

2. Science is different from other ways of learning about the world because science is more hands-on.

3. Scientists gather evidence by going out into the world and finding it. If their idea is correct, physical evidence in the world should be able to prove their idea correct.

4. Scientists need to be able to be good communicators because if they aren't, something might go wrong. If a scientist isn't communicating with their partner(s) during an experiment, something could go wrong due to a lack of communication.

5. Scientists need to be able to use math because, in a lot of experiments, math is required to calculate results and data.

6. Science helps us every day in different forms. For example, when you watch the weather forecast, the weather scientists are telling you the results of their data.

Answer:

True

Explanation: Covalent bonds are created when a nonmetal and metal combine. Ionic bonds are created when metal and metal combine

Answer:

true

Explanation:

Answer:D

Explanation:the more you wrap it around the mental the stronger it will be(I think)

Image D would have the greatest magnetic field due to more number of turns of wire.

The magnetic effect on electric currents, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. A force opposite to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.

The magnetic field of a permanent magnet pulls on ferromagnetic substances like iron and attracts and repels other magnets. In addition, three more magnetic phenomena cause a metaphors magnetic field to exert minute stresses on "nonmagnetic" materials. Image D would have the greatest magnetic field due to more number of turns of wire.

Therefore, image D would have the greatest magnetic field due to more number of turns of wire.

i dont really know the context of the other questions after but if you can give it to me i might be able to answer them

I hope this helps (i answered 1 and 2 only)

Answer:

There are protons, neutrons and electrons. The protons have positive charge and they are located in the nucleus. The neutrons have a neutral charge and are located in the nucleus as well. The electrons are located outside of the nucleus, but we never really know where exactly they are because they are always moving. They're most likely found in the orbital. They also have negative charge.

Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula H2. It is colorless, odorless, non-toxic, and highly combustible. Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.[8][note 1] Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds. For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons.

In the early universe, the formation of protons, the nuclei of hydrogen, occurred during the first second after the Big Bang. The emergence of neutral hydrogen atoms throughout the universe occurred about 370,000 years later during the recombination epoch, when the plasma had cooled enough for electrons to remain bound to protons.[9]

Hydrogen is nonmetallic, except at extremely high pressures, and readily forms a single covalent bond with most nonmetallic elements, forming compounds such as water and nearly all organic compounds. Hydrogen plays a particularly important role in acid–base reactions because these reactions usually involve the exchange of protons between soluble molecules. In ionic compounds, hydrogen can take the form of a negative charge (i.e., anion) where it is known as a hydride, or as a positively charged (i.e., cation) species denoted by the symbol H+. The H+ cation is simply a proton (symbol p) but its behavior in aqueous solutions and in ionic compounds involves screening of its electric charge by nearby polar molecules or anions. Because hydrogen is the only neutral atom for which the Schrödinger equation can be solved analytically,[10] the study of its energetics and chemical bonding has played a key role in the development of quantum mechanics.
