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 ​

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
