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.
T<Tc
a solid metal
conductivity
a very cold temperature
a low boiling point
no resistance
