This one is for folks with a good grasp of physics, I think.
Given a moving object with the following attributes:
Length: about 8' long
Circumference: 1.5'
Altitude: 8,000 feet
Air speed: 3,000 mph
Surface temperature of object: 65F
Ambient air temperature: 30F
Propulsion: none (read: no heat exhaust, etc)
Notes/parameters: object is conical shaped at its front. Surface temperature of object is constant, not affected by friction of moving through air at speed (that is not to say the air being displaced wouldn't heat up by the act of being disturbed that rapidly by such a fast moving object).
My question is... would this object leave any kind of visual contrail in the sky? Why or why not?
TIA..!
