Answer:
Without a specific figure 27.11 provided, I cannot refer to it directly. However, I can provide general information on how to rank the resistances of wires made of the same material.
The resistance of a wire is given by the formula R = (ρL)/A, where ρ is the resistivity of the material, L is the length of the wire, and A is the cross-sectional area of the wire.
To rank the resistances of wires made of the same material, we need to compare the values of (ρL)/A for each wire.
The wire with the largest resistance will have the smallest cross-sectional area (i.e., the thinnest wire) or the longest length, or both.
The wire with the smallest resistance will have the largest cross-sectional area (i.e., the thickest wire) or the shortest length, or both.
The middle wires will have intermediate resistances, depending on their length and cross-sectional area.
It's worth noting that the resistivity of a material can also depend on temperature, so if the wires are at different temperatures, that can also affect their resistances.
