Which statement best describes what happens in the area of converging streamlines? 0 The velocity increases and the pressure iIJLLELas?s o The velocity decreases and the pressure decreases 0 The velocity decreases and the pressure incceases U The velocity increases and the pressure decceases When fluid streamlines break into eddies and complex changing patterns, this is known as airflow. 0 Swirling - Turbulent 0 Was 0 Tornadic When a fluid is subjected to shear forces, it will 0 Retain its shape 0 Compress 0 Expand 0 Deform continuously Which of these historical figures achieved lighter—than—air flight? 0 The Wright brothers 0 The Montgolfier brothers 0 Sir George Cayley 0 Leonardo da Vinci Which of
the following is not consistent with Newton's laws of motion? 0 When a force is applied on a mass, there will be an equal and opposite resistance to the force that is proportional to the acceleration of the mass. 0 An object will be in a state of rest unless a force acts on it. o The change in velocity of a mass is due to the resultant offorces acting on it. 0 The momentum of a mass will remain constant until a force E on it. The temperature of air is directly proportional to o The pressure of the gas 0 The average kinetic energy of the atoms and molecules 0 The average velocity of the atoms and molecules 0 The quantity of heat added Aerodynamics is 0 The study of the motion of air and its interaction with a moving object The study of moving air The study of aircraft control The study of moving objects 000
