The potential energy of two atoms in a diatomic molecule is approximated by U(r)=a/r12āˆ’b/r6, where r is the spacing between atoms and a and b are positive constants. Part A Find the component of force along the line connecting the two atoms, Fr(r), on one atom as a function of r. Express your answer in terms of the variables a, b, and r. Fr(r) = nothing Request Answer Part B Find the equilibrium distance between the two atoms. Express your answer in terms of the variables a and b. rmin = nothing Request Answer Part C Is this equilibrium stable? Is this equilibrium stable? yes no Request Answer Part D Suppose the distance between the two atoms is equal to the equilibrium distance found in part A. What minimum energy must be added to the molecule to dissociate it-that is, to separate the two atoms to an infinite distance apart? This is called the dissociation energy of the molecule. Express your answer in terms of the variables a and b. E0 = nothing Request Answer Part E For the molecule CO, the equilibrium distance between the carbon and oxygen atoms is 1.13Ɨ10āˆ’10m and the dissociation energy is 1.54Ɨ10āˆ’18J per molecule. Find the value of the constant a. Express your answer in joules times meter in the twelth power. a = nothing Jā‹…m12 Request Answer Part F Find the value of the constant b. Express your answer in joules times meter in the sixth power. b = nothing Jā‹…m6 Request Answer Provide Feedback

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
