Question: One of the most promising materials for use as a superconductor is composed of use as a superconductor is composed of yttrium(a rare earth metal),

One of the most promising materials for use as a superconductor is composed of use as a superconductor is composed of yttrium(a rare earth metal), barium, copper, and oxygen. This material acts as a superconductor (i.e., transmits electricity with essentially no resistance losses) at temperatures up to 178 Degree C. If the temperature is then raised to 67 Degree C, and the coefficient of thermal expansion is 11.0 times 10 Degree C. determine the elongation of a 100-m long segment due to this temperature differential.
