Consider an object on a rotating disk a distance r from its center, held in place on the disk by static friction. Which of the following statements is not true concerning this object? O If the angular speed is constant, the object must have constant tangential speed. O If the angular speed is constant, the object is not accelerated. The object has a tangential acceleration only if the disk has an angular acceleration. O If the disk has an angular acceleration, the object has both a centripetal acceleration and a tangential acceleration. O The object always has a centripetal acceleration except when the angular speed is zero.
