Answer with Step-by -step explanation:
We are given that
b.
below the positive x-axis
Therefore, the angle made by vector A in counter clockwise direction when measure from positive x-axis=
x-component of vector A=
y-Component of vector A=
Magnitude of vector B=86 m
The vector B makes angle with positive x- axis=
x-component of vector B=
y-Component of vector B=
Vector A=
Vector B=
Vector C=A+B
Substitute the values
c.Direction=
The direction of the vector C=21.5 degree
Geographically throughout this area of Mexico, Central America Caribbean is located the Cocos plate. This area is scientifically known as the Central American subduction zone.
In order for a volcano to form, there is usually a clash between the technical plates that generates the elevation of the ground and the connection with ducts that release the magma from the earth. If this entire area is a subduction area, it will also be a land stress release area where volcano lines will be formed, that is, it is a convergent plate boundary area
A. overgrazing of livestock
Explanation:
Overgrazing of livestock is the ranch practice that contributes to soil erosion.
Soil erosion is the washing away of the top layer of the earth on which plant grows.
- Plants are covers of the earth and they prevent agents of denudation from actively washing away the soil.
- When livestock are introduced into a place, continuous grazing leaves the surface bare.
- The plants becomes depleted and the surface is exposed.
- This fast tracks the process of overgrazing.
