[{"name": "wire_resistance", "description": "Calculates the resistance of a wire based on its length, cross-sectional area, and material resistivity.", "parameters": {"length_m": {"description": "The length of the wire in meters.", "type": "int", "default": "copper"}, "area_sq_m": {"description": "The cross-sectional area of the wire in square meters.", "type": "float", "default": "copper"}, "material": {"description": "The material of the wire. Allowed values: \"copper\" (default) or \"aluminum\".", "type": "str, optional"}}}]
I have a project where I need to find out the resistance of different wires. First, I need to know the resistance of an aluminum wire that's 100 meters long with an area of 0.02 square meters. Then, can you also calculate the resistance for a copper wire that's 75 meters with an area of 0.015 square meters? Oh, and ignore the resistance of the surrounding material.
