Question

Use the graph on the right to answer the following questions. 354 a. Estmate the pressure at altitudes of 6,000 feet, 18,000 feet, and 21,000 feet bEstimate the altitudes at which the pressure is 24, 17, and 11 inches of mercury c. Estimating beyond the boundaries of the graph, at what alttude do you think the atmospheric pressure reaches 5 inches of mercury? Is there an altitude at which the pressure is exactly zero? Explain your reasoning. la 301 30 (5000 20 h25 20- 15- N10000,22) (20000 15 10 0000 10) 04 10000 20,000 30,000 Astude (feet a. The pressure at 6.000 feet is inches of mercury, and the pressure at 21,000 feet is inches of mercury, the pressure at 18,000 feet is inches of mercury (Round to the nearest integer as needed) feet, the altitude for which the pressure is 17 inches of mercury is b. The altitude for which the pressure is 24 inches of mercury is feet, and the altude for which the pressure is 11 inches of mercury is feet (Round to the nearest thousand as needed.) c. The altitude at which the atmospheric pressure reaches 5 is approximately (Round to the nearest thousand as needed.) Explain whether there is an altitude at which the pressure is exactly zero. Choose the correct answer below feet. A. The pressure reaches zero at an altitude of O B. The pressure approaches zero, but theoretically never reaches zero. (Ano p) aunsaad uy
