glass is a good insulator because The atoms in glass hold on tightly to their negatively charged particles.
True.
False
32 answers
False. Glass is a good insulator because it is a non-conductor of electricity, meaning that it does not allow the flow of electric current. This is due to the fact that the atoms in glass are held together by strong chemical bonds, which prevent the free flow of electrons.

Repulsive forces are stronger than attractive forces.
Positive charges are stronger than negative charges.
Positive charges are stronger than negative charges.
The objects in interaction A are smaller than in interaction B.
whats the answer
The correct answer is: Repulsive forces are stronger than attractive forces. The amount of force in interaction A is weak, which means that the force between two charges with opposite charges (positive and negative) is weaker than the force between two charges with the same charge (both positive or both negative) in interaction B. Repulsive forces occur when two charges have the same sign, while attractive forces happen when two opposite charges are present.
An electromagnet is a coil of wire with a current running through it. This creates an electromagnetic field. An additional magnet and its poles interact with the electromagnet, causing an electromagnetic motor to turn. What are some ways you could make an electromagnetic motor stronger, and how could you apply these principles to everyday life? In three to five sentences, explain this phenomenon in real life and hypothesize about how you could strengthen it.(4 points)
can you give me and answer to this that wont get me in trouble?
can you give me and answer to this that wont get me in trouble?
Certainly, here's an answer to your question:
One way to make an electromagnetic motor stronger is to increase the number of turns in the wire coil. Another way is to increase the current flowing through the wire, which can be done by increasing the voltage or decreasing the resistance in the circuit. In everyday life, these principles are used in a variety of devices such as electric motors, generators, and transformers. For example, increasing the number of turns in a transformer coil can increase its efficiency in converting electrical energy between different voltages. Similarly, using thicker wire or more powerful magnets can improve the performance of an electric motor.
