Why is it difficult to do on humid day a plastic ruler that has been rubbed with cloth have the ability to pick up small pieces of paper?
On a humid day, the air is more saturated with moisture, making it harder for objects to build up an electrostatic charge, as the moisture helps to dissipate the charge. When a plastic ruler is rubbed with cloth, it gains a negative static charge that allows it to attract small pieces of paper that are neutrally charged. The moisture in the air reduces the effectiveness of the ruler’s static charge, making it more difficult to pick up the paper.

Why does plastic ruler that has been rubbed with cloth have the ability to pick up small pieces of paper Why is this difficult to do in humid day?
When a plastic ruler is rubbed with cloth, it becomes charged with static electricity. This static charge attracts small pieces of paper due to the phenomenon of electrostatic attraction. On a humid day, the moisture in the air can dissipate the static charge more quickly, making it harder for the ruler to pick up the paper.
Is plastic ruler gets attracted towards pieces of paper when rubbed with oily hair?
Yes, when a plastic ruler is rubbed with oily hair, it can become statically charged. This static charge may attract lightweight objects like pieces of paper due to the electrostatic force between the ruler and the paper.
A plastic rod will pick up small pieces of paper when it has been rubbed with a cloth?
When the plastic rod is rubbed with a cloth, it becomes charged with static electricity. The rod becomes positively charged by stripping electrons from the cloth, making it attractive to the small pieces of paper which are negatively charged. This electrostatic force allows the plastic rod to pick up the small pieces of paper.
What is indicated when the paper bits move towards the rubbed plastic strip?
The movement of paper bits towards the rubbed plastic strip indicates the presence of static electricity. When the plastic is rubbed, electrons transfer from the plastic to the paper, causing the paper bits to be attracted to the strip due to opposite charges.
Why does a rubbed plastic object stay charged but a rubbed metal object lose its charge?
Rubbed plastic objects tend to hold onto their charge because they are insulators, meaning that they do not easily allow charge to flow. Rubbed metal objects, on the other hand, are conductors and can easily lose their charge as the electrons can move freely within the material and dissipate.

What is three examples of friction occurring in every day life?
Your ability to pick up anything (it is harder when your hands are greasy), your ability to walk (that is why it is more difficult on ice), why your hands feel warmer when they are rubbed together.

The movement of paper bits towards the rubbed plastic strip indicates the presence of static electricity. When the plastic is rubbed, electrons transfer from the plastic to the paper, causing the paper bits to be attracted to the strip due to opposite charges.

What type of charge does plastic collect when rubbed?
Plastic typically becomes negatively charged when rubbed, meaning it gains excess electrons. This can cause the plastic to attract positively charged objects or repel other negatively charged objects.
What happens if plastic rod is rubbed with silk cloth?
When a plastic rod is rubbed with a silk cloth, electrons are transferred from the silk to the plastic rod. This results in the plastic rod becoming negatively charged and the silk cloth becoming positively charged. This effect is known as triboelectric charging.
Why can rubber rubbed with wool attract small bits of paper?
The reason why the pieces of paper are neutral is that they contain equal amount of positive and negative charges and so they cancel each other out. When you bring a charged plastic comb to the pieces of paper, the charge opposite to that of the plastic comb will be brought to a part of the surface of the paper where the plastic comb is. Opposite charges attract each other, and since you're holding the comb, the pieces of paper will be attracted to the comb.
When a plastic rod is rubbed with a woolen cloth what happens?
When a plastic rod is rubbed with a woolen cloth, electrons are transferred from the wool to the plastic due to the friction between the two materials. This transfer of electrons creates a static charge on the plastic rod, giving it a negative charge and the wool a positive charge.
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.
When the tip of a ballpen is rubbed in your hair why do it attract light objects?
Rubbing the tip of a ballpoint pen in your hair can transfer some static electric charge to the pen. This static charge can make the pen attract light objects like paper bits or small pieces of plastic due to electrostatic forces between the charged pen and the objects.
