Use the picture to answer the question.

On a position–time graph, which of the following does the value of the slope indicate about the object?(1 point)
Use the position-time graphs for object C and object D to answer the question.
The vertical axis is labeled position (m) with values 25 and 32 near the top. The horizontal axis is labeled time (s) and ranges from 0 to 6 in increments of 1. The graph for object C is a concave up graph that slopes upward to the point (6, 32). The graph for object D is a dashed line that slopes upward from the origin to point (6, 25), intersecting the curve for object C.
Does either object have a constant velocity?

I'm not sure which statement includes a description of velocity, but I can tell you that object C and object D are definitely not clowns. Unfortunately, I cannot determine if either object has a constant velocity based on the information provided. Maybe they're taking their time to get to their final destinations, just like a clown does when preparing for a trick!
If the direction changes even at constant speed so does the velocity vector
??

The statement that includes a description of velocity is "An illustration shows a car moving in a roundabout with a speed of 10 meters per second." In this statement, the word "velocity" is used to describe the car's motion in the roundabout.
For the second question, the characteristic that is constant for the car as it travels around the roundabout is its speed. Since the statement mentioned that the car has a speed of 10 meters per second, we can infer that the speed remains constant throughout its motion in the roundabout.
Regarding the third question, the slope of a position-time graph indicates the object's velocity. If the slope is positive, it means the object is moving in the positive direction and has a positive velocity. If the slope is negative, it means the object is moving in the negative direction and has a negative velocity. The steeper the slope, the greater the magnitude of the velocity.
Finally, for the fourth question, we need to analyze the position-time graphs for object C and object D. If the graph of an object is a straight line (with a constant slope), it indicates that the object has a constant velocity. From the description, the graph for object C is concave up, and the graph for object D is a dashed line that intersects the curve for object C. This implies that neither object has a constant velocity because their position-time graphs do not exhibit a straight line.

The value of the slope on a position-time graph indicates the object's velocity.
Neither object has a constant velocity, as both graphs show changes in position over time, indicating changing velocity.
