Questions:

Question 17 Using a syringe, you inject a droplet of red dye into a glass of water. It takes 7.00 s for 1/3 of the dye molecules to diffuse a distance of at least 4.61 cm from the opening of the syringe. After an additional 13.4 seconds, what is the minimum distance from the syringe will 1/3 of the dye molecules have diffused? Q 4.07 cm Q 7.87 cm Q 5.06 cm Q 6.38 cm O 61.9 cm Question 18 At what height in the atmosphere is the pressure only 51% of the pressure at sea- level? (Assume a temperature of 150C and a molar mass of 29 g/mol for a typical air molecule.) 6.3 km 9.9 km 3.3 km 5.7 km 7.7 km Question 19 A giraffe has an aorta with a radius of 0.69 cm. The pressure gradient is 314 Pa/m. Assume blood is 2 times as viscous as water. What is the average flow speed of blood in this artery? 9.3 x 10-1 m/s 2.9 x 10-3 m/s 9.3 x 101 m/s 2.9 x 101 m/s 9.3 x 10-3 m/s
