● temperature
● density of medium
● speed of wind

sentence from the passage shows that the function of the river depicted here has carried through to modern times?
Well if u see here the graph is showing us 1.5 on the graph so we multiply that by 6 and we get 46 as our final anwser
Answer:
7 units, north
Explanation:
This is a problem of vector subtraction. We have:
- Vector A: magnitude 2 units, direction to the north
- Vector B: magnitude 5 units, direction to the south
If we take the north as positive direction, we can write
Since we want to find 
(vector subtraction), we have to change the sign of B, so we find:
And the positive sign means the direction is north.
