Answer
Please see the work below.
Work Step by Step
(a) We know that the centripetal acceleration is the acceleration which is perpendicular to the direction of motion and has a constant magnitude. It will produce a circular shape to the object's path.
(b) Since the object is in uniform circular motion, the object's velocity changes in direction but not in magnitude.
(c) We know that if the object is in uniform circular motion then the speed remains constant.
