What will happened to the sand if you placed the balloon rubbed with woolen cloth near it?
the sand would stand up
What happens when a polythene strip is rubbed on a woolen cloth and then placed near a thin stream of running water from a tap?
The polythene becomes negatively charged.
What cannot be charged easily by friction 1 a plastic scale 2 a copper rod 3an inflatted balloon 4a woolen cloth?
A copper rod cannot be charged easily by friction due to its low tendency to gain or lose electrons. Woolen cloth, an inflated balloon, and a plastic scale can be charged more easily through the transfer of electrons.
Is woolen gloves man made or natural?
Woolen gloves are made from natural fibers obtained from sheep. Wool is a natural material that is sheared from sheep, processed, and then used to create various products like gloves, sweaters, and socks.
Worsted system and woolen system?
The systems are used to process wool from fibre into fabric.
What will happen if a glass ruler is rubbed vigorously on a woolen cloth?
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.
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.
After rubbing a plastic rod with a woolen clothmark noticed that the rubbed plastic rod picked up saw dust.explain what happened?
Rubbing the plastic rod with a woolen cloth transferred electrons from the wool to the plastic, giving the plastic a negative charge. The saw dust, being positively charged, was attracted to the negatively charged plastic rod due to electrostatic forces, causing it to stick to the rod.
Which charge does ebonite rod acquire when rubbed with woollen cloth?
The ebonite rod acquires a negative charge when rubbed with woolen cloth because electrons are transferred from the woolen cloth to the ebonite rod.
What kind of electricity does the balloon have after it was rubbed on the woolen cloth?
The balloon will have static electricity after being rubbed on the woolen cloth. This results from the transfer of electrons between the balloon and the cloth, causing the balloon to become negatively charged.
What type of electric charge is acquired if a rubber balloon is rubbed with a woolen cloth?
The rubber balloon becomes negatively charged when rubbed with a woolen cloth. This is because electrons are transferred from the wool to the balloon, leaving the balloon with an excess of electrons and a negative charge.
What occurs in woolen fabric when the fibres are rubbed together when wet and warm?
When woolen fibers are rubbed together when wet and warm, they can felt together due to the agitation and moisture. This process causes the fibers to interlock and mat together, creating a denser and more compact fabric.
What will happened to the sand if you placed the balloon rubbed with woolen cloth near it?
the sand would stand up
What kind of electeic charge gets devloped on thr ebonite rod when rubbed rod when rubbed with a woolen cloth or fur?
When an ebonite rod is rubbed with a woolen cloth or fur, the ebonite rod gains a negative charge. This is due to the transfer of electrons from the wool or fur to the ebonite rod, creating an excess of electrons on the rod and resulting in a negative charge.
Can a woolen cloth be charged by friction?
Yes, woolen cloth can be charged by friction due to its ability to gain or lose electrons when rubbed against another material. This can result in a build-up of static electricity on the woolen cloth.
What happens when a rubber balloon is rubbed with woolen cloth?
When a rubber balloon is rubbed with a woolen cloth, electrons are transferred from the wool to the balloon, giving the balloon a negative charge and the cloth a positive charge. This causes the balloon to become electrostatically charged, making it stick to certain surfaces or repel other charged objects.
Will steel spoon attract pieces of paper when rubbed with polythene and woolen cloth?
No, rubbing a steel spoon with polythene and woolen cloth will create static electricity on the surface of the spoon, causing it to attract pieces of paper.
