In both graphs, speed will be measured in meters/second.
In graph A, the object travelled a distance of 40 meters in 4 seconds
In graph B, the object is at rest for 5 seconds.
These are the correct answers
Answer:
Tension.
Explanation:
The tighter a string is, the more tension is applied to it; the more loose a string is, less tension is applied to it.
Therefore, when you adjust the tightness of a string you are tackling with it's tension.

<em><u>Answer:</u></em>
zero acceleration
<em><u>Explanation:</u></em>
<u>Acceleration</u> is defined as the rate change of velocity with respect to time
<u>This means that:</u>
Now, since the velocity is given as a constant, this means that the value of the velocity does not change which means that the change of velocity is zero.
<u>Substitute in the formula:</u>
<u>Therefore,</u> for constant velocity, the acceleration is zero.
