A cylindrical rod 1.50 m long and 0.500 cm in diameter is connected to a power source that maintains a constant potential difference of 15.0 V between its ends, while an ammeter measures the current through it. It is observed that at room temperature (20.0 °C) the ammeter gives a reading of 18.5 A, while at 92.0 °C it gives a reading of 17.2 A. The thermal expansion of the rod can be ignored. Calculate:
a) the resistivity and b) the temperature coefficient of resistivity at 20 °C for the rod material.

- Helicobacter pylori (H. pylori) is a helically-shaped bacterium that is usually found in the stomach. It burrows through the gastric mucous lining to establish an infection in the stomach's epithelial cells (see photo). Approximately 90% of the people infected with H. pylori will never experience symptoms. Others may develop peptic ulcers and show symptoms of chronic gastritis. The method of motility of H. pylori is a prokaryotic flagellum attached to the back of the bacterium that rigidly rotates like a propeller on a ship. The flagellum is composed of proteins and is approximately 40.0 nm in diameter and can reach rotation speeds as high as 1.50 x 103 rpm. If the speed of the bacterium is 10.0 μm/s, how far has it moved in the time it takes the flagellum to rotate through an angular displacement of 5.00 * 10² rad?
