Did you diagram all the faults and folds correctly? Which fault and/or fold did you find most difficult to diagram?
1 answer:
A fold is a stack of planar surfaces that are bent during permanent deformation and this happens when the earth's crust is compressed together.
<h3>What is a Fault?</h3>This refers to the planar fracture that occurs in a volume of rock that causes significant displacement.
Hence, we can see that there are three types of fold and they are:
- (1) anticlines,
- (2) synclines
- (3) monoclines.
Please note that your question is incomplete so I gave a general overview of the concept to give you a better understanding.

a. 4.52 m/s south
Velocity is a vector, whose magnitude is defined as the ratio between the displacement of the object and the time taken for the displacement to occur:
where
d is the displacement
t is the time
Velocity is a vector, so it also has a direction, which corresponds to that of the displacement.
For the ball in this problem,
d = 9.5 m south
t = 2.1 s
Substituting, we find:
and the directiion is the same as the displacement (south).
b. 4.52 m/s north
For this part, we must keep in mind that the speed is the magnitude of the velocity; however, speed is a scalar, so it does not have a direction.
Here we are told that the tennis ball travels at constant speed, so on its way back from Liam to Katie the ball's velocity is still the same as before, therefore
However, this time the direction is opposite to before, since the ball is travelling in the opposite direction.
Therefore, the ball's velocity when Liam returns Katie's service is
4.52 m/s north
