Question

Tristan is an engineer working on a design for a new roller coaster. He wants the car to shoot out of the station very fast but needs a superconductor to be able to accomplish this. He is looking at different materials to use on the tracks of the roller coaster. What is necessary for his material to function as a superconductor? Check all that apply. ОТ< То a solid metal conductivity a very cold temperature a low boiling point no resistance
​

Answer 1

Answer:

Superconducting materials can transport electrons with no resistance, and hence release no heat, sound, or other energy forms. Superconductivity occurs at a specific material's critical temperature (Tc). As temperature decreases, a superconducting material's resistance gradually decreases until it reaches critical temperature. At this point resistance drops off, often to zero, as shown in the graph at right.
