If a bar of copper is brought near a magnet, the copper bar will be unaffected by the magnet.
"The potential on the surface of a conductor is always zero."
This statement is false. A good number of times we define a point's potential to be the amount of work that must be done to move 1 coulomb of charge from infinitely far away to that point. So if, let's say, the conductor had a net positive charge, then you would need to do a net positive amount of work to move 1 coulomb of charge from infinitely far away to any point on the conductor's surface. We have just provided a case for which the potential on the surface of the conductor is not 0.
Answer:
False
Explanation:
Friction force is a force that opposes the relative lateral motion of two solid surfaces in contact.
The answer is wavelength because The wavelength of visible light determines the color that the light appears. Light with the longest wavelength appears red, and light with the shortest wavelength appears violet. ... The wavelengths of visible light that an object reflects or transmits determine the color that the object appears to the human eye
Metallic bonding accounts<span> for many physical </span>properties of metals, such as strength, ductility, thermal and electrical resistivity and conductivity, opacity, and luster. I hope my answer has come to your help. God bless and have a nice day ahead!
