Displacement is +0.2 km, and distance is 4.6 km._4. Suppose a train is moving along a track. Is there a single, correct reference frame from which todescribe the train's motion?A Yes, there is a single, correct frame of reference because motion is a relative term.B. Yes, there is a single, correct frame of reference which is in terms of Earth's position.C. No, there is not a single, correct frame of reference because motion is a relative term.D. No, there is not a single, correct frame of reference because motion is independent of frame of reference.For items 5 - 6, refer to the situation: A biker rides north for 15 km from his starting position, then turns west 16 km._6.
