4. What is the relationship between resistance and length? 5. What is the relationship between resistance and area? 6. Given the form for the equation of a line is y = mx, and the resistance is R = (p/A) L, that means the slope for the first graph is p/A. If we rearrange the resistance as R = pL (1/A), that means the slope for the second graph is pl. Use this to determine the resistivity of the Play-Doh@ from the slope of both graphs separately. 7. Does the resistivity of Play-Doh@ change when the length or area changes? Explain your reasoning. Hint: A percent difference calculation will be helpful.\fTable 7: Resistance () Vs. 1/Area (m2) 1450 1440 1430 1420 1410 Resistance 1400 y =-0.0003x + 1404.9 1390 R2 = 0.0233 1380 1370 1360 0 5000 10000 15000 20000 25000 30000 35000 1/Area (m2)
