Please select all that are correct Select one or more: a. Spiral motion happens when both tangential and radial velocities are nonzero b. Rotational and translational kinematic equations are so similar only because Physicists do not like remembering new equations C. When a car is moving, the angular velocity and angular acceleration vectors of a wheel are parallel or antiparallel to the axle of that wheel O d. Equation "s=r•theta" is true whether theta is expressed in radians or degrees e. It is possible to apply two torques on a rotating body f. When a moon orbits a planet in a perfect circle and never changes its speed, it experiences no acceleration g. Angular acceleration and tangential acceleration both have the same units because they are both accelerations h. When two grandpas are riding a merry-go-round, the grandpa sitting closer to the center is less likely to lose his toupee because his speed relative to air is smaller
