The combination of a uniform flow and a source can be used to describe flow around a streamlined body called a half-body (see the Video). Assume that a certain body has the shape of a half-body with a thickness of 0.16 m. If this body is placed in an air stream moving at 20.6 m/s, what source strength is required to simulate flow around the body

The answer is c hope this

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
