Two argon atoms form the molecule Ar2 as a result of a van der Waals interaction with U0 = 1.68×10-21 J and R0= 3.82×10 the frequency of small oscillations of one Ar atom about its equilibrium position.

Explanation:

From the given information:

The elastic potential energy can be calculated by using the formula:

Making K the subject;

k = 2.3 × 10⁻² N/m

Now; the frequency of the small oscillation can be determined by using the formula:

where;

m = mass of each atom = 1.66 × 10⁻²⁶ kg

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
