Give an example of a superconductor

In superconductivity, the resistivity of a material becomes*1 pointZeroFiniteInfiniteNone of the above

The transition temperature Tc of all superconducting materials satisfies the relation*1 pointNone of theseT < TcT = TcT >Tc

The superconducting state is perfectly ____________ in nature*1 pointParamagneticDiamagneticFerromagneticFerrimagnetic

The critical field needed to destroy the superconductivity is*1 pointHc = H0 (T/ Tc)Hc = H0 (Tc / T)^2Hc = H0 [ 1 - (Tc / T)^2 ]Hc = H0 [ 1 - (T / Tc )^2 ]
