How does a substance become temporarily charged by induction when a charged object is brought near?
I'm not 100% sure because were just starting this in class today. Let's say you have a negatively charged ebonite rod and you brought it toward a neutral pithball (if you don't know what that is just picture a shere). Before you brought the rod near the pithball, the protons and electrons in the pithball are spread out evenly. When u bring the negatively charged rod towards the pithball the electrons in the pithball move to the otherside of the ball. The protons never move but are now closer to the negatively charged ebonite rod. So technically, it reacts like a positively charged object would and attrcts to the negative ebonite rod ( unlike charges attract). But once the ebonite rod is moved away from the pithball, the pithball is neutral. The pithball is always neutral because there's no transfer of electrons but I guess it is technically temporarily charged. I'm not sure if that's what your looking for but I hope it helped a bit.
How a glass rod charged when rubbed with wool?
When a glass rod is rubbed with wool, electrons are transferred from the wool to the glass rod, making the rod negatively charged. This transfer of electrons causes the glass rod to become statically charged, meaning it has an excess of negative charge.
What is a pithball?
It is a very light, nonconducting, substance that is used to demonstrate electrostatic forces. Typically a small amount is hung at the end of a string. When a charged rod is brought close to the pithball it polarizes the pithball molecules. That is, it attracts charges that are opposite the charged rod and repels the like charges. This causes the molecules in the pithball (which has zero net charge) to slightly rotate so the unlike charges are nearer the surface and closer to the rod. When this happens, there is a net attractive electric force on the pithball which causes it to swing (slightly) toward the rod. If the pithball touches the rod it will pick up some charge from the rod. All of a sudden it now has a net charge, which is the same sign as the rod's charges and the pithball will swing (strongly) away from the rod because like charges repel. The pithball was originally made from dried pith, a soft spongy material found in the stems of plants. Nowdays, lots of materials will work; dried corn cob, styrofoam etc. The requirement is that it be lightweight (so it will easily swing when subjected to the electric forces described above).
What kind of rod can be charged by rubbing it with a duster?
A glass rod can be charged by rubbing it with a duster. When the duster rubs against the glass rod, electrons are transferred between the two materials, resulting in the glass rod becoming negatively charged.
What happens if you rub a glass rod with a piece of silk and the rod becomes positively charged?
When you rub a glass rod with silk, electrons are transferred from the glass rod to the silk, leaving the rod with a net positive charge. This positive charge creates an electric field around the rod, which can attract negatively charged objects or repel positively charged objects due to the principles of electrostatics.

When a glass rod charged its placed near small pieces of paper bitsthe paperbits are attracted to the rodthen repelledexplain?
The glass rod aquires static electricity.the paper bits are negatively charged and the glass rod is positively charged.when it battracts the paper ,the both aquire like charges due to which they both are repelled.

When a glass rod and fur rubbed together electrons are transferred from the fur to rod. Is the fur charged If any positively or negatively charged How much compared to the rod?
Yes, the fur becomes negatively charged as it loses electrons to the glass rod. The glass rod becomes positively charged as it gains these electrons. The fur is negatively charged compared to the rod.
What kind of rod can be charged by rubbing it with a duster?
A glass rod can be charged by rubbing it with a duster. When the duster rubs against the glass rod, electrons are transferred between the two materials, resulting in the glass rod becoming negatively charged.
Will a positively charged glass rod be attracted to a magnet?
No, a positively charged glass rod will not be attracted to a magnet. Magnets attract materials with unpaired electrons or magnetic properties, which glass does not have.

When you rub a glass rod with silk, electrons are transferred from the glass rod to the silk, leaving the rod with a net positive charge. This positive charge creates an electric field around the rod, which can attract negatively charged objects or repel positively charged objects due to the principles of electrostatics.
How a charged rod placed near an uncharged metal object can repel?
When a charged rod is brought near an uncharged metal object, it induces a separation of charges within the metal object causing the electrons to move away from the charged rod. This separation of charges creates an attractive force between the charged rod and the metal object, leading to the repulsion of the metal object.
When a rod is brought near a neutral electroscope the leaves move apart. what best describes the charge on the rod?
The rod is charged. The leaves of the electroscope move apart due to electrostatic induction, where the negative charges in the leaves are repelled by the negatively charged rod, causing them to separate.
When a glass rod is rubbed with a silk cloth the charge produced in the glass rod is?
When a glass rod is rubbed with a silk cloth, the glass rod becomes positively charged. This is because electrons are transferred from the glass to the silk, leaving the glass with an excess of positive charge.
The metal rod becomes negatively charged as well through which process?
The metal rod becomes negatively charged through a process called conduction. When a negatively charged object is brought near the metal rod, electrons on the surface of the rod are repelled, causing them to move to the end of the rod farthest from the negatively charged object. This redistribution of electrons creates a negative charge on the metal rod.
