Best ResponseYou've already chosen the best response.1Clearly velocity is always changing, even the speed is constant. So not a. The direction of acceleration is constantly changing as well, even if the magnitude is the same. So not b. The acceleration is always towards the center and the same magnitude, so yes c. Because F = ma and F and a are vector quantities, and a is constantly changing direction, F isn't constant either, even if it always has the same magnitude. So not d.
