Theresa has a magnet and two coils of tightly bound copper wire. How could Theresa cause an electric current to flow through one of the copper wires? A. Remove a length of wire from one of the coils

B. Disconnect the coils and place them side by side

C. Carefully touch the magnet to one of the coils

D. Move the magnet up and down near one of the coils

Ithink it’s cancer risk

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 

If its history of, then b) because a) implies only present day (now)

The independent variable in this experiment is the angle at which the light from the ray box strikes the mirror.hope this .
