Final answer:
The radius of gyration for a spherical globule is not determinable from the provided options as the necessary information regarding the dimensions or mass distribution of the globule is not given.
Step-by-step explanation:
The question regarding the radius of gyration for a spherical globule is incomplete because the radius itself is not provided in the options. In physics, the radius of gyration is a quantity that describes how the mass of an object is distributed with respect to an axis. For a spherical object, it depends on the mass and the actual radius of the sphere. Without specific numerical information about the spherical globule itself, such as its mass distribution and dimensions, we cannot determine the radius of gyration. The options provided (a. 450 mol, b. 450 Å, c. 2.6 x 10^6 g/mol, and d. The radius is not provided) do not contain this information. Therefore, we conclude that we don't have enough information to answer the question accurately.
