Question

A fullerene is any spherical, ellipsoidal, or cylindrical molecule that consists only of carbon atoms. The first fullerene to be discovered was C60, which consists of 60 carbon atoms arranged in linked hexagonal rings, resembling the pattern formed by the stitching on a soccer ball. (a) Approximating the C60 molecule as a hollow spherical shell with a diameter of 0.684 nm, what is its moment of inertia about an axis through its center? Each carbon atom has a mass of 2.00 × 10-26 kg. Entry field with incorrect answer 0.00000000000000000000000000000000027369999999999995 kg·m2 (b) If the C60 molecule is rotating and its rotational kinetic energy is 1.68 × 10-21 J, what is its angular speed?
