Final answer:
To calculate the resistance of the nichrome wire, we need additional information such as the diameter or the resistivity of the wire.
Step-by-step explanation:
To calculate the resistance of the nichrome wire, we can use the formula:
R = ρL/A
Where R is the resistance, ρ is the resistivity of the material (in this case, nichrome), L is the length of the wire, and A is the cross-sectional area of the wire.
In this case, the length of the wire is 18 cm (or 0.18 m).
The cross-sectional area can be calculated as the product of the width and thickness of the wire. Since the diameter is not given, we cannot calculate the exact cross-sectional area. Therefore, we need additional information to calculate the resistance of the wire.
