(c) Two argon atoms form the molecule Ar2 as a result of a van der Waals interacction with U0= 1.68×10-21 J and R0= 3.82×100-10 m. Find the frequenccy of small oscillations of one Ar atom about its equilibrium position.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
