A Supersonic Airplane Heats Up Considerably When Traveling Through the Air

question 12

Multiple Choice

A supersonic airplane heats up considerably when traveling through the air at speeds greater than the speed of sound. As a result, the airplane during supersonic flight is longer than when it is at rest on the ground. Offer an explanation for this length change from a submicroscopic perspective.

• A)The engines on the supersonic plane are so powerful that they cause the plane's metal skin to stretch during accelerations.
• B)Materials expand as they are heated.
• C)Atmospheric air molecules hit the supersonic plane at great velocities causing the atoms of the planes metal skin to start moving faster.
• D)Both A and B are correct.
