What is the coeffecient of drag for the shape that has diameter 7.32[cm]? .
Use three sig. figs. or N/A if there is not enough information.
2. You have a large wind tunnel of crosssectional area 0.95[m2]. You have a set of shapes that are all the same shape except they each have a different crosssectional area. The wind speed is held constant at 3.2[ms1]. Assume air density is 1 [kg m3]. The slope of Drag versus Area for this data is 0.45. [Slope units left out purposefully by me for sake of next question.]

3. The slope from the plot of Drag versus Area in the question above has units of
[N]
[m^2]
[kgm^3]
No units
[Nm^2]
All three have me stumped
