If you want to prepare a voltaic cell that produces a potential of 1.50 V, you should select the respective oxidation (at the anode) and reduction (at the cathode) reactions that will achieve a standard potential as close to 1.50 V as possible. Construct a voltaic cell by labeling the electrode and solution components.

If there was no gravity then their would be no downword force on the football to have it return the the grownd, and if there was no friction (mainly air friction) then there would be no opposing force the stop the ball from moving through the air allowing the ball to travle ∞.

Hi, your answer is not correct. this is a cumulative  

Not what goes around on earth but the universe too.

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
