This point is called the epicenter. The epicenter is important when it comes to the Earth's surface, because it pinpoints where Earthquakes begin to take shape and occur. It is the place where the most damage is caused by an earthquake and is found above the hypocenter.
... low frequency and high amplitude.
Answer:
When the jet stream moves south, it moves its associated weather front, which causes winds from the north
Explanation:
If A is the measurement in the x-axis and B is the direction in the y-direction,
Magnitude = √(1.5² + (-3)²)
Magnitude = 3.35 units
Direction:
tan∅ = y/x
tan∅ = 3/1.5
∅ = 63.4°
Tan is negative in the second and fourth quadrants, and the values of x and y indicate that it is in the fourth quadrant. Therefore, the direction is 63.4° below the positive x-axis.
