6) Consider two models of a water molecule. For both models, the mass of the oxygen atom is 16 atomic mass units (amu) and the mass of each hydrogen atom is 1 amu. In both modelsthe distance between the center of the O and the center of each H is L = 0.096 nm and the angle between the two bonds is about  = 105o. In the first model, assume that each atom is a point mass. In the second model, assume that each atom is a solid, uniform sphere of radius 0.025 nm. You may keep your answers in units of amu and nm. A) What is the location of the center of mass in the first model, relative to the center of the O atom?B) What is the location of the center of mass in the second model, relative to the center of the O atom?C) What is the moment of inertia about an axis passing through the center of mass and perpendicularto the page, for the first model?D) What is the moment of inertia about an axis passing through the center of mass and perpendicularto the page, for the second model?E) What is the moment of inertia about an axis going vertically on the page, through the oxygen atom?
