Q. |
Carbon nanotubes display magnetoresistance at low temperature. |
A. | true |
B. | false |
Answer» A. true | |
Explanation: magnetoresistance is the phenomenon in which the resistance of a material changes on the application of a magnetic field. carbon nanotubes display this property at low temperature. in fact, it shows negative magnetoresistance as the resistance decreases with an increasing magnetic field. |
