AT&T 8:43 AM unf.loncapa.net Potential Energy in Molecules One model for the potential energy of a two-atom molecule, where the atoms are separated by a distance where ro 0.70 nm and Uo - 9.2 eV. Note: 1 ev - 1.6*10-19 J, You can use SI units, but CAPA will also accept these units that will simplify your calculations: [Force] eV/nm [Energy] ev [distancel nm What is the distance between the atoms when the molecule is in stable equilibrium? 0.2pts Submit AnswerTries 0/10 AT&T 8:43 AM a unf.loncapa.net If the distance between the atoms increases from equilibrium by r0.25 nm, then what is the force from one atom on the other associated with this potential energy? (Enter your answer as postive if they repel each other, and negative if they attract.) 0.2pts Submit Answer Tries 0/10 The atoms are oscillating back and forth. The maximum separation of the atoms is r2 1.8 nm. What is the kinetic energy of the atoms when they are separated by the equilibrium distance? K(req) 0.2pts Submit AnswerTries 0/10 8:44 AM unf.loncapa.net .'ll AT&T令 You can choose where the potential energy equals zero anywhere you want (you can add or subtract any constant to it). For this function, U(oo)0. This is very common for electromagnetic problems like you will see in Physics 2. If the potential energy function were defined as U(r) = Uo [(r0 / r)18. (ro / r)9] +U1 where U 8.0 eV, reanswer all of the previous questions using this new potential energy function eq K(req) = 0.2pts Submit Answer Tries 0/10 In another two-atom molecule that is breaking apart, the force from one atom to the other is given by where Fo 18.2 eV/nm and r2 1.8 nm. Find the change in potential energy of the molecule due to this force if the separation of the atoms changes from r 2.6 nm to r 4.2 nm 0.2pts Submit AnswTries 0/10
