Question

A probe descending through Mars' atmosphere records pressure as a function of altitude; the data are in the table below. Mars's atmospheric pressure is governed by the equation p=p0e−h/h0. Wolfson3.ch15.p80c.jpg Part A. Use the fitted line, in connection with the pressure equation, to determine Mars' surface pressure. Express your answer to three significant figures and include the appropriate units. Part B. Use the fitted line, in connection with the pressure equation, to determine the scale height h0. Express your answer to two significant figures and include the appropriate units. Altitude (km) 10 20 30 40 50 60 Pressure (Pa) 242 98.7 37.6 16.2 7.21 2.38

Answer 1

A)   Mars' surface pressure = (1.013 * 10⁵ * e^-2.5)/(13.86)

                                             = 600 Pa

B)   the scale height h0 = 50 * 600/242

                                     = 124 km
