A copper wire is made with the same diameter and length as the capillary tube in Problem 18. What is the ratio of the resistance of the capillary tube to the resistance of the copper wire?

(reference problem 18)

A glass capillary tube with a diameter of 0.50 mm and length 10 cm is filled with a salt solution with a resistivity of 0.10 m. What is the resistance?
