Answer:
|x| = √53
Explanation:
We are told that the vector starts at the point (0.0) and ends at (2,-7) .
Thus, magnitude of displacement is;
|x| = √(((-7) - 0)² + (2 - 0)²)
|x| = √(49 + 4)
|x| = √53
As oil ,coal ,gas ,solar ,wind and water power
3.87 i think but if its not correct then let me know.
D. both B and C will cause gas pressure to decrease because adding more gas is like adding more energy and reducing the space (volume) the atoms will move more quickly but won't have space, therefore pressure will increase.
