If your trombone was made of pure copper or pure zinc, it wouldn't sound nearly as beautiful as a brass trombone. 如果你的长号是纯铜或纯锌,它不会听起来像黄铜长号那么动听。 Another alloy, a combination of copper and nickel, resists corrosion. 另一种合金,铜和镍的组合,抗腐蚀。 It does no...
3. Line Attenuation Down/Up:It is the distance between you and the ISP and the quality of the copper to your house. It is also measured in dBs and you can check the number on your ADSL statistics page. The closer you are to the ISP, typically the better speeds you can get. It als...
Why does connecting a wire between two charged conductors make the potential the same? Explain why copper wire is a good conductor of electricity. Why are thick wires rather than thin wires usually used to carry large currents? Why do we have free electrons in metal and not in...
(a) Copper metal is used for making electric wires. (b) graphite is used for making electrode in a dry cell. View Solution Assertion (A): Copper is used to make electric wires. Reason (R): Copper has very low electrical resistance. View Solution The property / properties which enable...
Does cobalt(II) chloride dissolved in water possess electrical conductivity? Explain. Why is iron more reactive than copper? Explain why ionic solids do not conduct electricity in the solid state but are strong conductors in the liquid state and when dissolved in water. ...

If you have insulated or bare aluminum wires, there are a few things to remember to ensure you receive the best price at your scrap yard. Insulated aluminum wire is often used to replace copper wire in many instances as a cheaper and easier solution. While it is not quite as good a ...
Another alloy, a combination of copper and nickel, resists corrosion. It does not rust, even with prolonged exposure to water. Student: But what about the Statue of Liberty in New York Harbor? It's made of pure copper, but it turned green. Isn't that a sign of corrosion? Professor: ...
And, because you’re the only one with access to this connection, you can achieve the same levels of connectivity as fibre broadband, while still using copper wires, which can make it much more cost effective. EFM has become much more popular in recent years, largely due to the incr...
