Stable isotopic ratios often indicate the presence and rate of certain processe Which of the following are generally true? O Lighter isotopes preferentially pass through membranes Radioactive decay depletes (lightens) the isotopes Heavier isotopes preferentially pass through membranes Fossile fuels are depleted (lighter) because they have passed through many biological reactions before being stored. Lighter isotopes prefer to be in the higher energy states. Heavier isotopes prefer to be in the higher energy states. Fossil fuels are enriched (heavier) because they have been fossilized.

Asbestos is a fibrous silicate mineral with remarkably hightensile strength. But it is no longer used because airborne as-bestos particles can cause lung cancer. Grunerite, a type of as-bestos, has a tensile strength of 3.5x10^2kg/mm²(thus, a strandof grunerite with a 1-mm2cross-sectional area can hold up to 3.5x10²kg). The tensile strengths of aluminum and Steel No.5137 are 2.5104lb/in²and 5.0104lb/in², respectively. Cal-culate the cross-sectional area (in mm²) of wires of aluminumand of Steel No. 5137 that have the same tensile strength as afiber of grunerite with a cross-sectional area of 1.0μ m²
