The heat transfer coefficient for air flowing over a sphere is to be determined by observing the temperature–time history of a sphere fabricated from pure copper. the sphere, which is 12.7 mm in diameter, is at 66c before it is inserted into an airstream having a temperature of 27c. a thermocouple on the outer surface of the sphere indicates 55c 69 s after the sphere is inserted into the airstream. assume and then justify that the sphere behaves as a spacewise isothermal object and calculate the heat transfer coefficient.

Indoraptor for sure

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

The answer would ve running
