You have explored some interesting, informative, and amusing examples of models. Now it's time to get creative and make your own model. Here is the requirement checklist for your model:
-Model types can include drawings, diagrams, physical models, virtual simulations, or videos.
-Models must be created by you, not something selected from an online or outside source.
-Submit a presentation, picture, video, or screenshot of your model.
-Submit a one-paragraph summary describing the topic you chose, your model, what it represents, how you made it, and the specific science involved. It is important that you are using science terminology and are accurate.

Now that you know how to create and submit your model, you will need to choose a topic for your model. Choose one of the three topics listed below. Select each topic for an overview.

1- Conservation of Mass-Explore the law of conservation of mass. Model a physical or chemical change, and then demonstrate how mass is conserved before and after the change.
2- Atomic Theory-Explore the atomic theory of atoms. Create a model that represents the motion and intermolecular attractions of particles in solids, liquids, and gases.
3- Thermal Energy-Explore the effects of thermal energy. Model how adding or removing thermal energy affects motion in particles in a pure substance, such as water, or in a chemical reaction.
!!PLEASE CHOOSE ONE OF THE 3 ABOVE!!

and then the next shows which is a homologous and homogeneous compound or element

Answer:The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.

Explanation:

The amplitude​ of a wave is directly related to the energy of a wave.

Amplitude is the maximum distance covered by a body from the main point in the vibrating mode.

As we know that energy of the wave is directly proportional to the square of the amplitude:

E ∝ (a)²

As the amplitude of wave increases, energy carried by the wave is also increases. Higher energy increases the amplitude of the propagating wave.

The type of spectrum is produced when electromagnetic radiation is emitted or absorbed as electrons change energy levels in an atom is hydrogen spectrum.

The hydrogen spectrum is given by the scientist Bohr and it consist of series name lyman, balmer, paschen, bracklet and p- fund as the electromagnetic radiations splits into this.

The lyman series is formed when electrons jumps from any hige energy level to n = 1 and will be same for balmer , pachen ,bracklet and p-fund are obtained when electrons jumps from any higher energy level to n = 2,3,4 and 5 respectively.

Therefore, type of spectrum is produced when electromagnetic radiation is emitted or absorbed as electrons change energy levels in an atom is hydrogen spectrum.

Answer:

A benefit of the opinion of a scientific author is that you can see others points of view on a subject.  A drawback is that they are using an opinion and most likely not stating unbiased facts.

Explanation:

Hope this helps

Answer:

Highlights:

*Researchers in the sciences do not see access to the scientific literature as an especially important problem.

*Authors consider factors such as journal reputation and the absence of publication fees when deciding where to submit their work. In contrast, free access is not a significant factor in their submission decisions.

Implications:

*While open access has the potential to expand the authorship and readership of the scientific literature, that potential has not yet been realized.

*Librarians who encourage scientists to publish in open access journals should be aware of the authors' priorities and perspectives. Authors in the sciences tend to focus on citation impact, reputation, and accessibility to a specialized readership—not breadth of readership, copyright, or access status.

*Journal publishers that charge publication fees may want to consider alternative sources of revenue. Authors' resistance to publication fees is a major barrier to greater participation in open access initiatives.

Explanation:

Answer:

Wave speed, frequency and wavelength in refraction

Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

Answer:

Waves. Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly.

Answer:

The Answer is A

Explanation:

Please let me know if I am wrong

The transformation takes place in the generator is mechanical energy is transformed into electrical energy.  Hence option A is correct.

Energy transformation is defined as the conversion of energy from one form to another. The passage of energy from one place to another is known as energy transfer. When energy transforms, it goes from one type to another.

Hydroelectricity is a type of renewable energy that produces electricity by harnessing the force of moving water. Mechanical energy is transformed into electrical energy in a generator. Most generators create alternating current as their source of electricity. A generator spins when a turbine's blades rotate due to falling water, converting the mechanical energy of the spinning turbine into electrical energy.

Thus, the transformation takes place in the generator is mechanical energy is transformed into electrical energy.  Hence option A is correct.
