2. What should the graph representing the relationship between the resistance of a copper wire of uniform cross-sectional area and the wire's length at constant temperature look like? 3. Which wire has the highest resistance? Length (m) 10 Wire Cross-SectionalArea (m²) A 2 x 10-6 1 x 10 2 x 106 1 x 106 10 C 1 1 What is the resistance of a 0.60 meter long silver wire with a diameter of 0.01 meter? 4. A copper wire has a resistance of 200 2. How much resistance would a second copper wire with twice the cross sectional area and the same length have? 5. 6. Which segment of copper wire has the highest resistance at room temperature? 1.0 m length, 1.0 x 10° m cross sectional area b. 2.0 m length, 1.0 x 10° m cross sectional area c. 1.0 m length, 3.0 x 100° m cross sectional area d. 2.0 m length, 3.0 x 10° m cross sectional area If the cross sectional area of a metallic conductor is halved and the length of the conductor is doubled, the resistance of the conductor will be a. 2 7. a. halved b. doubled c. unchanged d. quadrupled

The question is whether these relationships are linear or non-linear, can you please inform me on how I'd be able to tell?
