13)What can you say about the motion of a body if its velocity-time graph is a straight line inclined with the time axis?
The body moves with uniform velocity.
14)Which of the following conclusions can be drawn if a velocity-time graph is parallel to the time axis?
A)The body is moving with uniform velocity
B)its acceleration is zero
C)its speed can be found by finding the area of the graph.
D)both A and B
I don't know B?
13). No, since the graph is inclined, velocity is not constant. There is a steady acceleration.
14.) The answer is D)
If a velocity-time graph is parallel to the time axis, it means that the velocity of the body remains constant over time. This indicates that the body is moving with uniform velocity. Therefore, conclusion A can be drawn, which states that the body is moving with uniform velocity.
Additionally, since the velocity is not changing, the acceleration of the body is zero. Therefore, conclusion B can also be drawn, which states that its acceleration is zero.
As for conclusion C, finding the area under the graph of a velocity-time graph gives us the displacement of the body, not its speed. The speed can be found by calculating the magnitude of the velocity at any point on the graph.
Hence, the correct answer is D) both A and B - the body is moving with uniform velocity and its acceleration is zero.
