Given the formula Y = F / (A × Δl / l), rearrange to express Δl in terms of other variables.

1. V = A / l, which implies A = V / l.
2. Thus, Δl can be written as Fl² / (VY).
3. As a result, plotting Δl against l² will yield a linear graph.
4. F can also be expressed as YA / l × Δl.

Correct answer: As a result, plotting Δl against l² will yield a linear graph.

Solution

The equation Δl = Fl² / VY shows that Δl is directly proportional to l². Hence, a graph of Δl versus l² will be a straight line.
