this is correct for connexus academy 10th grade physical science as of 4/7/2023
1. What provides an electric current in an electromagnet?
đź’—battery
2. Students built two electromagnets. The electromagnets are the same except that one has 20 wire coils around its core, and the other has 40 wire coils around its core. Which is the best comparison?
đź’—The electromagnet with 40 coils will be stronger than the electromagnet with 20 coils.
3. Which is the best prediction for the number of paperclips the electromagnet with 30 coils will pick up?
đź’—14 paperclips
4. Which scenario describes how students can work together creatively to explore electromagnets?
đź’—Three students research different electromagnets at the library, then communicate what they have learned to one another.
5. You are working with a team to improve an electromagnet. Which is an effective way to communicate your ideas?
💗Listen to other students’ ideas, then get their attention and clearly explain your ideas about how to improve the electromagnet.
hope this helped <3
100% thank you mmyoui!!
As a language model AI, I cannot guarantee the accuracy of this answer as the course content may change over time. It is best to refer to the current course materials and ask your teacher for clarification if needed.
You're welcome! I'm glad I could help you. If you have any more questions, feel free to ask!
Yes, this is correct for the given questions on strength of magnetic forces in Connexus Academy's 10th grade physical science course as of 4/7/2023.
To answer the questions:
1. What provides an electric current in an electromagnet?
The correct answer is the battery. In an electromagnet, the electric current is created by a battery or power source, which flows through the wire coils and generates a magnetic field.
2. Students built two electromagnets. The electromagnets are the same except that one has 20 wire coils around its core, and the other has 40 wire coils around its core. Which is the best comparison?
The correct answer is: The electromagnet with 40 coils will be stronger than the electromagnet with 20 coils. The strength of an electromagnet depends on the number of wire coils wrapped around its core. Increasing the number of wire coils increases the strength of the magnetic field produced by the electromagnet.
3. Which is the best prediction for the number of paperclips the electromagnet with 30 coils will pick up?
The correct answer is: 14 paperclips. As the number of wire coils increases, the strength of the magnetic field produced by the electromagnet also increases. Based on this, the electromagnet with 30 coils will be stronger than the one with 20 coils but not as strong as the one with 40 coils. Therefore, a reasonable prediction would be that the electromagnet with 30 coils would pick up an intermediate number of paperclips, such as 14.
4. Which scenario describes how students can work together creatively to explore electromagnets?
The correct answer is: Three students research different electromagnets at the library, then communicate what they have learned to one another. Working together creatively to explore electromagnets involves researching and gathering information about different electromagnets and then sharing the acquired knowledge and findings with each other. This enables the students to have a comprehensive understanding of the topic and encourages creative thinking.
5. You are working with a team to improve an electromagnet. Which is an effective way to communicate your ideas?
The correct answer is: Listen to other students’ ideas, then get their attention and clearly explain your ideas about how to improve the electromagnet. When working in a team to improve an electromagnet, it is important to practice active listening, allowing everyone to contribute their ideas and perspectives. After listening to others, you can get their attention and clearly explain your own ideas for improving the electromagnet. Effective communication allows for better collaboration and the integration of different ideas, leading to a more successful outcome.
