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.

Image A
Image B
Image C
Image D
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.
What is magnetic field?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.

Marianne designs an experiment involving electrically charged objects. She wants to know which objects will be attracted to a negatively charged balloon. Identify the test variable, the outcome variable, and the control variable for this experiment.
(Side note; please use ALL the variables. the outcome, the test variable, and the control variable! If you get it right I'll mark you the brainliest so good luck :)
Answer: When one object is rubbed against the another, static electricity can be created because the rubbing creates a negative charge, carried by electrons
Explanation:
When we rub a balloon on our head, it causes opposite static charges both on hair and balloon. When the balloon is pulled slowly away from our head, we can see these two opposite static charges attracting one another and making our hair stand up.
On rubbing a balloon on wool, the electrons move from the wool to the balloon's surface. The rubbed part of the balloon has a negative charge. Balloons, the electrical insulators, resist electric charges flowing through them. So only a part of the balloon has negative charge (where the wool is rubbed) and other places remain neutral.
When a balloon is rubbed to wall, it will be attracted to the wall. The charge is not immediately discharged as the wall is an electrical insulator.
When we rub the balloon against metal, the extra electrons in the balloon quickly leave the balloon and move into the metal so the balloon is no longer attracted and does not adhere.

Describe the three parts of an atom. Where are they located and what kind of charge do they have (positive, negative, or neutral)
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.

why does the amount of water pressure determine the size of bubbles in the water
Answer:
Water vapor pressure is a function of temperature (and pressure as well). It increases with the temperature. When vapor is produced on the heat surface, bubble forms. The size of the bubble is determined by the buoyancy and the water pressure at the location.

when do the highest tides happen?
(select all that apply.
when the moon is full
When the moon is new
When the moon is in the third quarter
When the moon is in it the first quarter.
When the moon is full, the highest tides happen. Therefore, the first option is correct option.
Tides are the rise and fall of sea levels induced by the moon's and sun's gravitational influences on Earth's oceans. These celestial bodies' gravitational pull causes a tidal bulge on the side of the Earth facing them, as well as a second bulge on the opposite side.
The highest tides, known as spring tides, occur when the moon's and sun's gravitational forces align. This occurs during the full and new moon phases of the moon. During these phases, the sun's and moon's gravitational pulls reinforce each other, resulting in higher high tides and lower low tides.

Why is foam fight chemical or a physical change
Answer:
This CHEMICAL REACTION produces carbon dioxide gas (which form the bubbles) and water. The addition of dish soap is what causes the foam by trapping the tiny carbon dioxide bubbles before they can pop. The reaction is also taking in heat (ENDOTHERMIC), which causes the foam to feel cool to the touch.

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.
