You can tell whether velocity is changing because velocity is the rate/speed of motion of something in a direction either it increase or decrease in the speed or a change in its direction that will causes its velocity to change.

Answer:
D
Explanation:
The north field of a magnet is the positive side. Arrows pointing out of a side = positive
Explanation:
In local galactic group the force of expansion of universe is overcome by the force of attraction due to gravity. Best example is our own galaxy milky way and another giant galaxy in our local group Andromeda. Andromeda having enormous gravity is pulling milky way towards itself, overcoming the force of expansion.
So, there are possibilities of collision despite the expansion of universe at a rapid pace. It is estimated that the milky way and Andromeda will collide each other after about 50 billion years from now.
Answer:
It says about the motion and the graph of the object is stationary, basically travelling at the same speed at any time of the graph. It will never change.
Explanation:
To draw a diagram:
1. Draw an object and represent the speed as stationary and constant at any time.
