Can two negatively charged balloons move apart without ever touching?

no, because objects have to touch to exert forces that attract and repel.

yes, because electric charges have electric fields surrounding them that allow them to exert forces on other objects without touching them.

no, because the space between objects is actually filled with charged particles that all interact.

yes, because electrons from one ballon jump to the other and push it.

B.Yes, because electric charges have electric fields surrounding them that allow them to exert forces on other objects without touching them i think

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
