<h3>Answer;</h3>
<em><u>Sand Spit or Spit </u></em>
<h3><u>Explanation;</u></h3>
- <em><u>Long shore drift is the process that occurs when a sheet of water moves on and off the beach, in other words the swash and back swash</u></em>, thus capturing and transporting sediment on the beach back out to the sea.
- <em><u>Sandbar</u></em> is normally formed when the sandspit stretches across a bay and connects the two sides. <em><u>Headland</u></em> is a high piece of land that extends out onto the sea. <em><u>Sea stacks </u></em>on the other hand results from the collapsing of the roof of the arch.
Answer:
159 N
Explanation:
The force of friction is a resistive force that acts against an object in motion (or on the verge of moving).
There are two types of force of friction:
- Force of static friction: it occurs when the object is still at rest
- Force of kinetic friction: it occurs when the object is sliding on a surface and it is in motion
In this problem, we are in the 2nd situation, so we want to calculate the force of kinetic friction.
This force is given by:

where
is the coefficient of kinetic friction
N is the normal force exerted on the object
For the sled and the girl in this problem,
is the coefficient of kinetic friction
N = 636 N is the normal force
So the force of friction is
