Given the graph of the positive velocity of an object moving along a line, what is the geometric representation of its displacement over a time interval [a, b]? Let the horizontal axis measure time in terms of t. Choose the correct answer below: A. The object's displacement can be represented geometrically as the area between the graph and the t-axis from t = a to t = b. B. The object's displacement can be represented geometrically as the average value of the graph between t = a and t = b. C. The object's displacement can be represented geometrically as the slope of the graph between t = a and t = b. D. The object's displacement can be represented geometrically as the difference between the value of the graph at t = a and the value of the graph at t = b.
Which one of the following represents displacement -time graph of two objects $A$ and $B$ moving with zero relative velocity?
