AnotherMolecule In another two-atom molecule that is breaking apart, the force from one atom to the other is given by F12 = Fo (r/r₂) e-r/r₂)² where Fo= 12.7 eV/nm and r₂ = 2 nm. Find the change in potential energy of the molecule due to this force if the separation of the atoms changes from r = 3 nm to r = 4.3 nm. Click here for a hint AU = Hint: Hint: <

(a) Tony Hawco (m362 kg), a Newfoundland based skater decides to have his first ride on the new halfpipe at Bannerman Park. We will use the lowest point in the halfpipe as our reference point h=0. Vo=2.00 m/s R=3.00 m V,=7.00 m/s h=0 B. A.

One model for the potential energy of a two-atom molecule, where the atoms are separated by a distance r, is U(r) = U0 [(r0 / r)16 - (r0 / r)9] where r0 = 0.70 nm and U0 = 7.0 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[distance] = nm r_eq = 7.6 *10^-1 nm If the distance between the atoms increases from equilibrium by r1 = 0.20 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). F_r (r_eq +r_1) = ? The atoms are oscillating back and forth. The maximum separation of the atoms is r2 = 2.2 nm. What is the kinetic energy of the atoms when they are separated by the equilibrium distance? K(r_eq) = ?

One model for the potential energy of a two-atom molecule, where the atoms are separated by a distance r, is U (r) = Uo[()¹5 (70)6] where ro = 0.6 nm and U₁ = 7.7 eV. Note: 1 eV = 1.6 x 10-¹⁹ J. Some helpful units: [Force] = eV/nm [Energy] = eV [distance] = nm Equilibrium Distance Force Kinetic Energy AddedConstant AnotherMolecule In another two-atom molecule that is breaking apart, the force from one atom to the other is given by F12 Fo (r/r₂) e-(1/₂)² = where Io = 12.7 eV/nm and r₂ = 2 nm.
