When a plastic rod is rubbed with a cloth the plastic rod gains what?
When a plastic rod is rubbed with a cloth, the plastic rod gains a static electric charge. This charge is due to the transfer of electrons between the rod and the cloth, creating an imbalance of positive and negative charges on the rod's surface.
Examples of objects whose density is less than water's?
Objects like wood, oil, plastic, and cork have densities that are less than water, which is why they float when placed in water. Materials with lower densities than water displace less water than their own weight, causing them to float.
What can stick to a magnet but doesn't conduct electricity?
A material like plastic can stick to a magnet but does not conduct electricity. This is because plastic is an insulator and does not allow electric current to flow through it.
Does insulators keep us from electric shocks?
Yes, insulators help prevent electric shocks by blocking the flow of electricity and maintaining a barrier between the electrical current and people or objects. Materials like rubber, plastic, and glass are commonly used as insulators to reduce the risk of electric shock.
Is plastic spoon conductor or insulator?
Plastic spoons are insulators as they do not conduct electricity. This is because plastic is a non-metallic material and does not allow electric current to flow through it easily.
Why would an electric wire be covered with an insulatos such as plastic?
Plastic being nonconducting, it avoids electrocution when covered around electric wire.
What is the general name given to nonconducting materials?
The general name given to nonconducting materials is insulators. Insulators do not allow electric current to flow easily through them due to their high resistance to the flow of electrons. Examples of insulators include rubber, plastic, and glass.
What is a soft nonconducting solid at room temperature?
A soft nonconducting solid at room temperature could be a material like rubber or plastic. These materials have low electrical conductivity and are pliable at room temperature due to their molecular structure, allowing them to be easily deformed.
Why is electrical wir coated with plastic?
The electric wire is coated with plastic to serve as an electric insulator.
Can electric charges pass through a plastic bottle that is full of water with a plastic cap?
No. The plastic would keep the electric charge
What is the volume in cubic feet of 500 kg of plastic?
That depends on the type of "plastic" There are polymers with densioties close to 2 and others (especiall those that are expanded or foamed that have densities around 0,1. So somewhere between 300 cuft and 15 cuft.
Is electric guitar made of plastic?
There are many different types of electric guitars, and they are made with a variety of materials, including plastic.
Why is it not safe to use plastic in Electric ovens?
because plastic melts.
why is the handle of an electric iron made up of plastic or wood?
It is made an plastic
Why do different plastics separate like oil and water?
because they have different densities. waters density is 1.000 and plastic is 3.842
When a plastic rod is rubbed with a cloth the plastic rod gains what?
When a plastic rod is rubbed with a cloth, the plastic rod gains a static electric charge. This charge is due to the transfer of electrons between the rod and the cloth, creating an imbalance of positive and negative charges on the rod's surface.
Why are are electric wires covered in rubber or plastic?
