Level 1 (0 points). I Also really wanted to burn CDs; unfortunately, I read under Section D, under the title APPLE MUSIC USAGE RULES of the new Terms and Conditions, that they plainly stated that we can't burn any Apple Music Products.
There are many different types of drag. 1  The most commonly encountered are: 2  Parasitic Drag, composed of Form Drag, which is the result of the aerodynamic resistance to motion due to the shape of the aircraft, Skin Friction Drag, which is due to the smoothness or roughness of the surfaces of the aircraft, and.
Drag is a force and is therefore a vector quantity having both a magnitude and a direction. Drag acts in a direction that is opposite to the motion of the aircraft. Lift acts perpendicular to the motion. There are many factors that affect the magnitude of the drag. Many of the factors also affect lift but there are some factors that are unique to aircraft drag. We can think of drag as aerodynamic friction, and one of the sources of drag is the skin friction between the molecules of the air and the solid surface of the aircraft.
