A ravine is a smaller version of a canyon that is typically formed by stream bank erosion. Ravines are greater in scale than gullies, but smaller than valleys.
<h3>What is ravine?</h3>
A ravine is a slope landform with relatively steep sides,Ravines may or may not contain active streams running along the down slope channel that produced them.
Ravine are frequently characterized by intermittent streams, since their geographic size is too small to maintain a perennial watercourse.
Hence, a ravine is a smaller version of a canyon that is typically formed by stream bank erosion.

Answer:
F = 6666.7 N
Explanation:
Given that,
Mass of a chip, m = 0.1 mg
Initial speed, u = 0
Final speed,
Time of collision,
We know that,
Force, F = ma
Put all the values,
So, the required force is 6666.7 N.
When The mass has no displacement.
Answer:
Spring constant = 63.77 N/m
Explanation:
Given the following data;
Force = 44 N
Extension = 0.69 m
To find the spring constant;
Force = spring constant * extension
Substituting into the formula, we have;
44 = spring constant * 0.69
Spring constant = 44/0.69
Spring constant = 63.77 N/m
Answer:
force required to push the block = 219.714 lb
Explanation:
GIVEN DATA:
weight W of block = 250 lb
coefficient of friction = 0.2
consider equilibrium condition in x direction
.........................(1)
consider equilibrium condition in Y direction
.....................(2)
SOLVING 1 and 2 equation we get N value
N = 326.36 lb
putting N value in either equation we get force required to push the block = 219.714 lb
