Answer:
D. Salt Weathering
Explanation:
Salt weathering is defined as a geomorphic process resulting in the physical disintegration of rocks or stones and in the fretting of their surfaces. Often you tend to find the best examples of salt weathering in dessert areas and coastal areas. You can find three distinct types of weathering which are biological weathering, physical weathering, and chemical weathering.
Answer:
The basic principle on which the electric iron works is that when a current is passed through a piece of wire, the wire heats up. This heat is distributed to the sole (base) plate of the electric iron through conduction.
a. The particle has position vector
b. Its velocity vector is equal to the derivative of its position vector:
c. At 
, the particle has position
That is, it's 56.0 m to the right and 49.0 m up relative to the origin, a total distance of 
away from the origin in a direction of 
relative to the positive 
axis.
d. The speed of the particle at is the magnitude of the velocity at this time:
Then its speed at this time is
One point will be X1,Y1 and the other will be X2,Y2. It does not matter which is which except that X1 and Y1 have to be the same point and X2 and Y2 have to be the same point. For example, let's say you were given (2,3) and (6,8). No matter which point is X1,Y1 and the other is X2,Y2, the slope will still be 5/4.
The rise is the change in y from one point to the other. The run would be the change in x from one point to the other.
125 kmph
250=2
X=1
250/2= 125
