Please help with question 6,7 and 8 Exercise 3: Resistance, Resistivity and

Exercise 3: Resistance, Resistivity and Area of a Wire. (R = pL/A) Data Table 3 Area (cm ) Resistance (0) 1/A (cm z) 2.00 2.50 0.50 4.00 1.25 0.25 6.00 0.833 0.1667 8.00 0.625 0.1250 10.00 0.500 0.1000 12.00 0.417 0.0833 14.00 0.357 0.0714 6. Graph your data in Table 3 using a program like Excel as described in the Lab Procedures. Plot Resistance (ohms) on the Y axis and plot Area (cm?) on the x-axis. How does the resistance depend on the area? 7. Graph your data in Table 3 using a program like Excel as described in the Lab Procedures. Plot Resistance (ohms) on the Y axis and plot 1/Area (cm ) on the x-axis. Find the slope from your graph (ohms-cm); i.e. resistance over inverse area). Slope = 2cm 8. From the slope of the line, find the resistivity of the wire p. Show the details of this calculation in your Calculations Sheet. Identify the calculation as "Table 3 Resistivity Calculation". Enter the resistivity value from your calculation here: P = -0.602(1/0.50-2cm^2 x -0.301=-602) Hint: pay attention to all parts of the resistivity equation in determining the slope
