Identify the correct statements concerning the friction between two...

Limiting friction is the maximum possible value of static friction, which means $f_{s} \le f_{L}$. Thus, limiting friction is never less than static friction.

For any given pair of surfaces, the coefficient of static friction $\mu_{s}$ is always greater than the coefficient of kinetic friction $\mu_{k}$.

Since limiting friction is given by $f_{L} = \mu_{s}N$ and kinetic friction by $f_{k} = \mu_{k}N$, it follows that $f_{L} > f_{k}$. Hence, limiting friction is always greater than kinetic friction.

Static friction is a self-adjusting force that ranges from $0$ to $f_{L}$. Therefore, it can be less than kinetic friction, making the statement that static friction is always greater than kinetic friction incorrect.
