4. When a fan is turned on, it changes electrical energy into ______ energy.
A. motion
B. magnetic
C. gravitational
D. electromagnet
5. An experiment discovered that a particular material was a poor conductor of electricity. This material would most likely be used as an
A. conductor
B. insulator
C. switch
D. resistor
1. A
2. B
please check
A- Correct - Fans change electrical energy into kinetic energy (motion energy is an acceptable term too)
B- Correct- If a material isn't a good conductor, it can be used as an insulator.
thanks, and yes I was referring to question 4 and 5 sorry!!
YES THE CHOICES ARE RIGHT
Did u finish this ??? I'm am working on it today.
They are right
To check whether the given answers for questions 4 and 5 are correct, we need to understand the concepts involved.
For question 4: When a fan is turned on, it changes electrical energy into _____ energy.
The options given are: A. motion, B. magnetic, C. gravitational, D. electromagnet.
In this case, the correct answer is A. motion. When a fan is turned on, it converts electrical energy into the motion of the fan blades, which allows it to produce airflow.
For question 5: An experiment discovered that a particular material was a poor conductor of electricity. This material would most likely be used as a(n) ______.
The options given are: A. conductor, B. insulator, C. switch, D. resistor.
In this case, the correct answer is B. insulator. A poor conductor of electricity would be used as an insulator because it restricts or prevents the flow of electric current through it.
Based on the provided information, the given answers for questions 4 and 5 are correct:
4. A. motion
5. B. insulator
