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
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.
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
The perspective which best explain this is SOCIO-CULTURAL PERSPECTIVE. Socio-cultural perspective is a theory which explains the awareness of situations surrounding people and how their behavior is determined by their environment, culture and social values.
