What is polythene rod made of?
The polymer "polythene".
If you rub a copper rod rather than a polythene rod the copper rod will not stay charged why not?
Copper is a good conductor of electricity, so when it is rubbed, any charge accumulated on its surface quickly redistributes throughout the rod and dissipates. This rapid conduction of charge prevents the copper rod from retaining a net charge like a polythene rod, which is an insulator and can hold onto excess charge more effectively.
Would a ten foot piece of electrical conduit attached to the peak of a shed acting as an extension for a bird feeder attract lightning?
While metal structures can attract lightning, a 10-foot piece of electrical conduit is relatively short. It may attract lightning if it is the tallest point in the immediate vicinity. To minimize risk, install a lightning rod or ensure that the conduit is not the highest point on the shed.
What happens if you rub a glass rod with a piece of silk and the rod becomes positive?
When you rub a glass rod with a piece of silk, electrons are transferred from the glass to the silk, resulting in the glass rod becoming positively charged due to a deficiency of electrons. The silk, having gained electrons, becomes negatively charged. This process is an example of triboelectric charging, where contact and friction between two materials cause the transfer of charge. As a result, the positively charged glass rod can attract negatively charged objects or repel other positively charged items.
What happens if the negatively charged rod is brought close to another negatively charged rod?
they repel remember, opposites attract and likes repel.
What happens when a perspex rod is held near a polythene rod?
When a perspex rod is held near a polythene rod, the two rods will interact due to static electricity. If the perspex rod is positively charged (after being rubbed with a cloth), it will attract the negatively charged polythene rod, which has gained electrons. This attraction occurs because opposite charges attract, resulting in an electrostatic force between the two rods. If both rods are similarly charged, they will repel each other.
What happens if a perspex rod is rubbed to a piece of paper instead of a polythene rod?
Rubbing a perspex rod against a piece of paper will likely transfer some electrons from the perspex to the paper, causing the perspex rod to become positively charged and the paper to become negatively charged. This can create an electrostatic attraction between the rod and the paper.
Will a charged polythene rod repel or attract paper?
A charged polythene rod will attract paper. When the rod is charged, it develops an electric field that exerts a force on the charged particles in the paper, causing the paper to be attracted to the rod.
What happens when you rub a piece of cloth with a polythene rod?
Rubbing a piece of cloth with a polythene rod transfers electrons from one material to the other due to friction. This causes the cloth to become negatively charged and the polythene rod to become positively charged, leading to the attraction between them due to opposite charges.
What is polythene rod made of?
The polymer "polythene".
What charge does a polythene rod acquire when rubbed with a duster?
A polythene rod acquires a negative charge when rubbed with a duster. This is because electrons are transferred from the duster to the polythene rod, leaving the rod with an excess of electrons and a negative charge.
What is a perspex rod?
It's a rod made out of a certain type of plastic, i have most commonly seen them used in science lessons at high school, if you rub them against a piece of fur they will become negatively charged because electrons from the fur travel into the perspex rod. hope that helps. alice.
What happens to a perspex rod when it is rubbed by a duster?
Both are originally have equal electrons and protons. After rubbing, electrons move to the duster, from the rod. The duster, as it gains electrons, has more electrons than protons, therefore becoming negatively charged. The rod, losing electrons, becomes negatively charged. then, the rod is able to momentarily pick up little bits of paper for short periods at a time.
What charge is on a polythene rod?
A polythene rod can acquire a negative charge when it gains extra electrons through friction with another material.
When metal rod is rubbed against polythene bag or sweater it attracts or not?
When a metal rod is rubbed against a polythene bag or sweater, the rod becomes charged with static electricity. The metal rod may be attracted to the polythene bag or sweater due to the opposite charges present on each material.
When a polythene rod is rubbed with a duster it becomes negatively charged . why?
When polythene is rubbed with a duster, electrons from the duster are transferred to the polythene rod, giving the rod an excess of electrons and making it negatively charged. This transfer of electrons creates an imbalance of positive and negative charges on the surfaces, resulting in the rod becoming negatively charged.
What happen when a polythene rod is rubbed with a cloth?
When a polythene rod is rubbed with a cloth, electrons are transferred between the two materials, causing the polythene rod to become negatively charged and the cloth to become positively charged. This results in the attraction between the two materials due to opposite charges.
