The Newton's second law of motion
\[
F = m\cdot a
\]
states that the the acceleration \(a\)
of the body is directly proportional to the acting force,
\(F\).
The positive constant of this proportionality is the mass of the body,
\(m\). This
law can be also rewritten in the form of inverse proportionality between convenient
other quantities. Which of the graphs describes the Newton's second law properly,
assuming one of the quantities which appear in the Newton's law is constant?

The resistance \(R\)
of a wire is a function of a material constant
\(\rho \), the length
\(l\) and the cross
section \(S\).
It can be computed from the formula
\[
R =\rho \cdot \frac{l}
{S}.
\]
Assuming two of the quantities are inversely proportional when the other two
quantities are constant, identify the graph which describes this relationship properly.
