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.
The diagram shows a generator powered by a water turbine. Based on the diagram, what type of energy transformation takes place in the generator?
A
Mechanical energy is transformed into electrical energy.
B
Chemical energy is transformed into kinetic energy.
C
Electrical energy is transformed into potential energy.
D
Electrical energy is transformed into chemical energy.
The transformation takes place in the generator is mechanical energy is transformed into electrical energy. Hence option A is correct.
What is energy transformation?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.

Need this asap ill mark brainliest On the Internet, many authors post opinion articles on scientific topics. What are the benefits and drawbacks of these opinion articles in regard to scientific discussion?
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.

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.
