Pour into a container with a longitudinal expansion coefficient of five times ten to the negative power of five, a liquid with a longitudinal expansion coefficient of three to fifty-five hundredths multiplied by ten to the negative power of four. Increase the temperature of the set by a few degrees Kelvin to increase the height of the liquid inside the container by five percent? (Liquid does not spill out of the container)

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
