Could you fill in the following blanks and provide an explanation, thank you.
For each of the following statements, choose the correct option. . For this statement, refer to Figure 1 below. The displacement of an object going from A to C is zero . The displacement of an object during any time interval is always same time interval the distance it travels during that For this statement, refer to Figure 2 below. The acceleration at point D is . For this statement, refer to Figure 1 below. The average velocity of an object going from A to B is zero Displacement is a vector whereas distance is a scalar. Zero greater than less than equal to greater than or equal to less than or equal to cannot tell X(m) t(s) t(s) Fig. 1 - Path taken by an object Fig. 2 - Velocity as a function of time Submit Answer Incorrect.

1)The displacement of the object going from point A to point C is less than zero.
Since the displacement is a vector and is measured as the difference in distance between the final and initial points. In this case, the final point is zero and the initial point is a positive quantity. So the difference must be less than zero.
2)The displacement of an object during any time interval is always less than that of the distance it travels through the same time interval.
As an example, in the figure1, the distance covered by the object from A to C is the distance from A to C through the curved path along the point B, This will be greater than the displacement which is the shortest path between A and C (A straight line from A to C).
3)The acceleration of the object at the point D is less than zero.
The before the reaching the point, the object was having a positive velocity and after leaving the point, the object has a negative velocity. So the net acceleration at the point is negative.
4)The average velocity of the object is less than zero.
The slope of the x-t curve gives the average velocity. Since from A to B the curve has a negative slope, the average velocity must be negative.
