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.

What are the states of matter for the outer core and the inner core? Which data that you collected in the virtual lab could help explain this difference? Explain your reasoning.
The mantle is solid/plastic, the outer core is liquid, and the inner core is solid. The relative melting points of the various layers (the nickel-iron core, the silicate crust, and the mantle), as well as the rise in temperature and pressure with depth, are to blame for this. The data that you collected in the virtual lab could help explain this difference is test ideas and observe results.
What state of matter is the inner core made of?The inside core is a rock. The area of the Earth that is at its centre is known as the inner core. It is quite hot and has a lot of iron and nickel in it.
Because it is constructed of extremely dense, or heavy, components like iron and nickel, the inner core is solid. These materials don't "melt" easily while being extremely heated, hence they remain solid.
The inner core is kept solid despite the high temperatures by the strong pressure that exists there. Outer Core: The liquid outer core is 1300 miles (2092 kilometres) thick. The temperatures of the inner and outer cores, which range from 7200 to 9000°F (4000 to 5000°C), are extraordinarily high and predominantly made of iron and nickel.
Thus, The mantle is solid/plastic, the outer core is liquid, and the inner core is solid.

Mercury orbits the Sun at an average distance of 0.4 AU. Neptune orbits the Sun at an average distance of 30 AU. How do their average distances in miles from the Sun compare?
PZ HURRYYYYYYYYY
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.

Can water get more wet?
Answer: No, water can't get any wetter
Explanation:
Water is not wet, any fluid can be considered "wet" if wetness is a result of the sensation caused by a movement of fluid over the skin.
The reason Water seems wet-
Because Water is surrounded by other water molecules which is surrounded by itself. The molecules are touching, so water would then seem "wet".
If you're under-water then you are wet, because you're skin has been saturated in a liquid.
In everyday language, we often describe something as being "wet" when it is in contact with or covered by water or another liquid. However, from a scientific standpoint, the term "wet" refers to the ability of a liquid to adhere to a surface.
Cohesion refers to water molecules sticking together, while adhesion refers to water molecules sticking to other substances. These properties allow water to spread and form a thin film over surfaces, making them appear wet.
In this context, water cannot become "more wet" because it already exhibits the characteristic of wetness. When water comes into contact with a surface, it will continue to spread and adhere until it reaches a state of equilibrium. Once the surface is fully covered and no additional water can adhere, the wetness remains constant.
So, while water can interact with and cover surfaces to create a wet sensation, it does not become "more wet" beyond its inherent wetting properties.

Which of the following electromagnets would have the greatest magnetic field?
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.

6.What are some examples of how science can help us in our everyday lives?
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.

True or False. If your skin is wet, the body's resistance to electric shocks increases
Answer:

Explanation:
as water is not a good conductor of electricity, the electricity will sort of ignore the water on the skin and enter the body. Electric shocks are more possible only when the surface/body is wet, therefore I say it is true.
