because copper is a metal and polthene is a non metal?
Infact, polythene doesn't even conduct electricity....
A copper wire is made out of metal which is therefore a good conductor and will take electricity easily. While rubber is the material people use to protect from electricity as the material is not fit for carrying electricity.
Because a rubber is not a conductor it is an insulator.
In copper electrons move freely among atoms than in rubber tuber
why is it easy to charge polystyrene by rubbing but not copper
The copper tube is more resistant.
Copper is metal and polythene non metal
natural rubber is more elastic than synthetic rubber
The density of rubber can vary, and the density of wood can vary even more (unless we're putting air in the rubber to make foam). In general, however, wood is less dense than rubber, rubber is less dense than copper, and copper is less dense than mercury.
In rubber electrons cannot freely move among atoms as in copper.
Even though gold and copper are in the same family, copper is much more reactive than gold. This is why Copper rusts more than gold, and why there are so many copper compounds (IE copper silicate...). Copper is higher in the family, giving it these characteristics.
they are more useful because they have more copper inside .
natural rubber is more elastic than synthetic rubber
N0. The common belief is that if an object elongates easily the object is more elastic . But in Physics the object which gives more resistance to elongate is said to be more elastic . Such objects will have high Young's modulus . Steel is more elastic than copper . The Young's modulus for steel is 210 G Pa For copper it is 117 G Pa Elongation for steel is 35% and for copper it is 45% For rubber Young's modulus is 0.02 G Pa and elongation is 500 % During collision two clay balls will stick together. We call it inelastic collision . Two steel balls will rebound easily and the collision is elastic collision.
No, because rubber stretches then snaps back into place. Spring steel might be as elastic as rubber BUT normal steel is much less elastic than rubber.
Rubber is more elastic than iron ... the main reason that you seldom find underpants manufactured with iron wastebands.
The density of rubber can vary, and the density of wood can vary even more (unless we're putting air in the rubber to make foam). In general, however, wood is less dense than rubber, rubber is less dense than copper, and copper is less dense than mercury.
The elongation is more in rubber than glass for same deforming force applied on them. whose elongation is more its elasticity is less. Because less elongation will have more elasticity and vice verse.The answer is "glass"
In rubber electrons cannot freely move among atoms as in copper.
It is because the measure of stiffness in elastic material and the quantity used to make materials. Also because it is more common than other elastic modulus measured.
In science, elasticity is the tendency of a material to return to its original size and shape when it is released from being stretched or compressed. By this definition steel is more elastic than rubber.
Copper is a better conductor of not only electricity, but also heat. This is because copper is a metal.
In science, elasticity is the tendency of a material to return to its original size and shape when it is released from being stretched or compressed. By this definition steel is more elastic than rubber.
Contrary to popular expectation, rubber is not really elastic, atleast not the way scientists define elasticity. Rubber is actually much less elastic than steel. Thus for best results we use steel or similar materials, say brass, in this experiment.
