Technically, it doesn't. Static electricity is not something some things have or don't have. It is built up by two objects coming in contact with eachother. Some objects are more negative or positive than others, and the more positive items tend to lose their electrons more easily than the negatives, who tend to gain electrons. The gain/loss of electons happens on contact. Rubbing creates more contact, and therefore more gain/loss. The shock comes when a positively charged object touches a grounded item, such as a metal post or a person. Electrons jump to the object through the grounded item from the ground. If said object is a human, (s)he will feel a jolt of electricity, which we call static. Note: I call positive objects positive because they become positive on contact. I use the same reasoning with negative objects.
A ruler can become positively charged through the process of friction, which involves rubbing it against another material, such as a piece of cloth. During this interaction, electrons can be transferred from the ruler to the cloth, leaving the ruler with a deficit of electrons and thus a net positive charge. This phenomenon is due to differences in the materials' electron affinity, which determines how easily electrons are transferred.
A metal ruler is stronger than a plastic ruler in terms of the kinetic theory because the metal atoms are arranged in a tightly packed, orderly structure which gives it greater strength and cohesion. The metal ruler's atomic structure allows it to better withstand external forces and deformation compared to the more loosely arranged atoms in a plastic ruler.
A transparent ruler may be a polycarbonate. An opaque-type ruler may be a polystyrene copolymer such as high-impact polystyrene (HIPS). Recycled polystyrene can be turned into rulers, among other things.
no it can not .it is because a magnetic meterial can made in to magnet
When a cloth is rubbed against a ruler, electrons are transferred between the two materials, resulting in one becoming positively charged and the other negatively charged. This transfer alters the distribution of electric charges within the atoms of the cloth and ruler, leading to static electricity. As a result, the atoms in both objects experience an imbalance of charges, which can cause them to attract or repel each other. This change in electrical properties is what leads to the observable effects, such as the cloth sticking to the ruler.
A plastic ruler typically does not have a charge as it is an insulator and does not conduct electricity. If a ruler were to become charged, it would likely carry a small amount of static electricity, which could be either positive or negative depending on the materials it has come into contact with.
Because electrons will be transferred from the cloth to the insulating rod. But the charge will be negative.
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.
it generates magnetic field and thus get charged
Rubbing a glass ruler on a woolen cloth will create a static charge on the ruler due to the triboelectric effect, where electrons transfer between the materials. The glass ruler will become negatively charged as it gains electrons from the woolen cloth, resulting in static attraction to objects with a positive charge.
A ruler may attract your hair due to static electricity. When you rub a ruler against your hair, electrons transfer from one surface to the other, causing one to become positively charged and the other negatively charged. This attraction leads to your hair sticking to the ruler.
Plastic is generally used as an insulator. A plastic ruler would not be a conductor of electricity.
A charged up ruler will typically attract water. The charge on the ruler can induce a temporary polarization in the water molecules, causing them to be attracted to the ruler.
when you rub the plastic ruler on e.g. a yellow duster it takes the electrons (which is the negative charge) from the yellow duster and the plastic ruler becomes negatively charged. The paper has both protons and electrons the protons are positively charged. and very much like a magnet the negative is attracted to the positive hence the paper sticks to the ruler Hastings Tarrant
It's a ruler made of acrylic. Essentially, it's a clear plastic ruler.
A charged ruler attracts small pieces of paper due to the electrical force between the charges. The ruler becomes charged when electrons are transferred to or from it, creating an electric field around it that exerts a force on the neutral pieces of paper, causing them to be attracted to the ruler.
