Answer:
The second vector
points due West with a magnitude of 600N
Explanation:
The original vector
points with a magnitude of 200N due east, the Resultant vector
points due west (that's how east/west direction can be interpreted, from east to west) with a magnitude of 400N. If we choose East as the positive direction and West as the negative one, we can write the following vectorial equation:

With the negative sign signifying that the vector points west.
B. Density. I hope this helps!
Answer:
The answer is B- it decreases from 40 J to 37 J.
Explanation:
Because as you see it was at 8 then it went down 3 just like how it started at 40 and went down 3 to 37.
