Answer:
The average kinetic energy of SF₆(g) is 4.98 kj/mol.
Explanation:
Given that,
Kinetic energy of UF₆(g)=4.98\ kj/mol
We need to calculate the average kinetic energy of SF₆(g)
Using formula of average kinetic energy
Where, k = Boltzmann constant
=Avogadro number
R =gas constant
Here, average kinetic energy depends only on temperature not on special molar mass
So, The SF₆(g) average kinetic energy is same as UF₆(g
Hence, The average kinetic energy of SF₆(g) is 4.98 kj/mol.

Answer:
From the formula of force:
since AB and k are constants:
x is a constant of proportionality
• when force is 4N, separation distance is 1
therefore, equation becomes
when r is doubled, r becomes 2. find F:
The Newton’s law Nikolas would use to come up with this idea is the <span>Third law that states:
</span><span>When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
</span>
So, in this case, let's name the first Body A which is the skateboard and the second body B which is <span>the compressed carbon dioxide in a fire extinguisher. Then, as shown in the figure below, according to the Third law:
