Well you never specified what you're asking... however, this might help you learn the concepts of displacements and magnitude.
: The official displacement formula is as follows: s = sf - si. s = displacement; si = initial position; sf = final position
magnitude is the quantitative value of seismic energy. It is a specific value having no relation with distance and direction of the epicentre.
the magnitude of a vector in any dimension. For a 2d vector the formula is [math]|z| = \sqrt{x^2+y^2}[/math], where x and y are the x and y components of the vector respectively.
Answer:
Distance= 84 meters
Displacement= 20 meters
Direction= West
Explanation:
The starting position we know is 10 meters eastward and the final position is 18 meters westward. Remember the equation for displacement is Delta=final position minus the initial position. So its 18-10=8. The next equation that we would have to solve would be 22-8, because our starting position is 8 meters and our final position is 22, so final minus the initial remember. Then 22-8=14. Finally the last equation we would have to solve would be 34-12, again our initial position is 12 meters and our final position is 34 meters, therefore the answer to 34-14=20. So we end up with our displacement as 20 meters and don't forget to include the direction, which is West.
