Answer:
Least to most elongated: tungsten, copper, aluminum, nylon.
Explanation:
Materials with high Young's modulus are difficult to stretch. σ = Yε and ε = ΔL/L so an object with a high Young's modulus (Y) subject to a certain tensile stress (σ) will have a smaller strain than an object with a smaller Young's 's modulus subject to the same tensile stress. If strain (ε) is smaller, then ΔL will also be smaller.
When two stars are bound together gravitationally and orbit a common mass, theyre known as B. BINARY STARS.
