<u>Answer</u>
3.7 Km south
<u>Explanation</u>
The definition of displacement is the distance traveled in a specific direction. It is the vector quantity. We add displacements like the way we add vectors.
Taking the direction towards North to be positive (+1.7 Km), the distance towards south would be negative (-5.4 Km).
Now lets add the two values.
(+1.7) + (-5.4) = 1.7 - 5.4
= - 3.7 Km But negative was towards south.
∴ Answer = 3.7 Km south.
You first find the mass and the volume of that object. Then you divide mass ÷ volume
Answer:
1110 N
Explanation:
First, find the acceleration.
Given:
Δx = 300 m
v₀ = 85.5 km/h = 23.75 m/s
v = 0 m/s
Find: a
v² = v₀² + 2aΔx
(0 m/s)² = (23.75 m/s)² + 2a (300 m)
a = -0.94 m/s²
Find the force:
F = ma
F = (1180 kg) (-0.94 m/s²)
F = -1110 N
The magnitude of the force is 1110 N.
When hard stabilization structures such as groins are used to stabilize a shoreline, the change in the longshore current results <u>deposition of sediment. </u>
On the upcurrent side of the barrier, sediment is deposited as the longshore current slows.
What is Hard stabilization?
- Hard stabilization is the prevention of erosion through the use of artificial barriers.
- Other hard stabilization structures, such as breakwaters and seawalls, are built parallel to the beach to protect the coast from the force of waves.
- Hard stabilization structures, such as groins, are built at right angles to the shore to prevent the movement of sand down the coast and maintain the beach.
- These constructions are made to last for many years, but because they detract from the visual splendor of the beach, they are not always the ideal answer.
- Additionally, they affect the habitats and breeding sites of native shoreline species, interfering with the ecosystem's natural processes.

Answer:
R = 6.8
Explanation:
Given data:
Richter scale![R = log(\frac{I}{I_o})](https://tex.z-dn.net/?f=%20R%20%3D%20log%28%5Cfrac%7BI%7D%7BI_o%7D%29)
where R - magnitude of earthquake of Richter scale
I - quake's intensity ![= 10^{6.8} \times I_o](https://tex.z-dn.net/?f=%3D%20%2010%5E%7B6.8%7D%20%5Ctimes%20I_o)
- minimum intensity earthquake
Plugging all information in the equation to get Richter's scale
![R = log(\frac{10^{6.8} \times I_o}{I_o})](https://tex.z-dn.net/?f=R%20%3D%20log%28%5Cfrac%7B10%5E%7B6.8%7D%20%5Ctimes%20I_o%7D%7BI_o%7D%29)
![R = log(10^{6.8})](https://tex.z-dn.net/?f=R%20%3D%20log%2810%5E%7B6.8%7D%29)
R = 6.8
