One of the common source is C. <span>Spraying crop fields with pesticides
After spraying the crops with pesticides, the waste will fall and absorbed by the ground.
This will contaminate all substance that exists (nutrients that needed by the plants) in that ground and make that area became toxic for years.</span>
Answer:
Explanation:
His displacement is 0 because he ended up exactly where he started.
This is the same question that I just answered.
Have present the definition of acceleration:
a = Δv / Δt, this is change in velocity per unit of time.
a and v are in bold to mean that they are vectors.
1) a body traveling in a straight line and increasing in speed: CORRECT:
Acceleration is the change in velocity, either magnitude or direction or both. So, a body increasing in speed is accelerated.
2) a body traveling in a straight line and decreasing in speed: CORRECT
A decrease in speed is a change in velocity, so it means acceleration.
3) a body traveling in a straight line at constant speed: FALSE.
That body is not changing either direction or speed so its motion is not accelerated but uniform.
4) a body standing still : FALSE.
That body is not changind either direction or speed.
5) a body traveling at a constant speed and changing direction: CORRECT.
The change in direction means that the body is accelerated. The acceleration due to change in direction is named centripetal acceleration.
Answer:
1.75 / 2 = 0.875 m
Explanation:
Provided the mirror is vertical and you are standing upright.
It could be most any altitude if the mirror is allowed any orientation.
