Select all that apply. a hypothesis is always correct determined before experimentation begins the experimental factor that changes in response to a change in the independent variable testable and falsifiable

I believe a hypothesis is determined before experimentation begins. A hypothesis is a scientific state of prediction. It describes in concrete terms what you expect will happen in ones study. However, not all studies have hypothesis. Often times a study may be designed to be explanatory. A study may have one or more hypothesis. Hypothesis is an educated prediction that can be tested.

Are there options for 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
