Answer:
The 3rd graph
Explanation:
A free body diagram is a diagram which shows all the forces acting on an object.
The problem asks us to find the free body diagram of block A, so we must find all the forces acting on block A.
We have 3 forces acting on block A in total:
- The force of gravity (its weight), which pushes the block downward (in the diagram, it is the force represented with 
- The tension in the rope 1, which pulls block A upwards: this force is represented with 
- The tension in the rope 2, due to the weight of block 2, which pulls block A downwards: this force is represented with 
Based on the direction of these 3 forces, the correct diagram is the 3rd one.
The speed of light : 299 792 458 m / s
The approximate value for the distance between the two points is <span>3.162277663.16227766</span>.
<span><span>√10</span>≈<span>3.16227766

Electrons have a smaller wavelength than visible light, leading to higher resolution.
Answer:
-1m
Explanation:
I'm assuming it means that you treat the distance travelled as a displacement vector (distance of a particular direction and magnitude)
If he turns 180 degrees, he is travelling in the exact opposite direction to his original direction of travel. Therefore if he was travelling 5m in one direction, then afer his turn he travels 6m in the exact opposite direction. Opposite directions can be interpreted as the negative of the original direction.
Resultant vectors are the sum of vectors.
The sum of vectors is equal to 5m + - 6m = -1m
