2. Which are all facts about the magnetic field around a wire? * The field is circular around the wire
The field only exists while there is current going through the wire
The field gets stronger the farther away you get from the wire
The less current passed through the wire, the stronger the magnetic field
The field gets stronger with more current passing through it

Definitely the indoraptor

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 relationship of both of them

Ibelieve the answer is d. macula  hope my answer has you : )
