Science Homework Help

I’m working on a science multi-part question and need a sample draft to help me learn.

Assignment Questions:

• In your own words, explain what a wave is. Why are waves important? What are three properties of every wave? Describe those properties. Answer in ~1 paragraph.
• One fascinating thing about light is that exhibits both particle behavior and wave behavior. What is one specific piece of evidence that it behaves as a particle? What is one piece of evidence that it behaves as a wave? Answer in your own words in 1-2 paragraphs.
• What is reflection? Explain it in your own words, and provide an example. What is refraction? Explain it in your own words, and provide an example. Then explain why these two concepts are important. Answer in 1-2 paragraphs.
• Explain Coulomb’s law as if you were teaching this concept to a 6th grader. Be specific, but make sure your explanation is age-appropriate. Why is Coulomb’s law important? Answer in ~1 paragraph.
• Historically, some of the first power plants distributed direct current to customers. But today, all household electricity comes in alternating current form. Why is alternating current used for power distribution, rather than direct current? Be sure to include a description of alternating current and direct current in your response. Answer in ~1 paragraph.
• What is the main difference between permanent magnets and electromagnets? What are some uses/applications of permanent and electromagnets? Provide at least three examples. Answer in ~1 paragraph.
• Compare and contrast the elements carbon (C) and sodium (Na) in terms of (a) number of protons and electrons (assume the atoms are neutral), (b) mass number, and (c) whether they are metals, nonmetals, or metalloids. Then compare and contrast metals and nonmetals: how do they differ? Answer in ~1 paragraph.
