plz help This is for Rock formations...only 5 sentences if not more
For this assignment, consider the processes that create coastal rock formations. While these processes create beautiful and interesting rock formations, they are also often highly destructive. Think for example what could happen to a town that is near the sea and has buildings being exposed to the same forces that create sea cliffs, arches, and stacks. How do you think those buildings stand up against the forces of the waves? Make a discussion posting to describe what you think happens to buildings exposed to sea erosion and then suggest ways that the destruction associated with this force can be stopped for people who live in towns near the coast.
After you make your post, comment on at least one of the posts of your classmates.

Answer:
The coastal zone is not a stable and constant environment, but a dynamic place that can change rapidly in response to natural processes such as seasonal weather patterns. Waves, winds, currents, tides and storms are the major forces on the coast.

The weight of the fluid that an object displaces is equal to the buoyant force acting on the object is
spring force
Archimedes Principle
buoyant force
Hooke's Law
Answer:
Archimedes' Principle
Explanation:
Its because Archimedes' Principle states "that the buoyant force on an object is equal to the weight of the fluid displaced by the object.... If you want to know the buoyant force on an object, you only need to determine the weight of the fluid displaced by the object."

A +6.33 uC charge q1 is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. What is the value of q2?
Answer:-4.1858
Explanation: I hate Acellus
If A +6.33 μC charge q₁ is attracted by a force of 0.115 N to a second charge q2 that is 1.44 m away. then the value of q₂ = 4.23 μC.
What is coulomb's law ?Electrostatic force is a force of attraction or repulsion between two unlike or like charges respectively. when like charges come closer to each other, they gets repel by one another and it gets attracted for unlike charges. Force of attraction or repulsion between two point charges are given by coulomb's law. The force of attraction between two charges are given by coulomb's law.
the law states that the force of attraction or repulsion between two point charges is directly proportional to product of magnitude of both the charge and inversely proportional to square of the distance between them.
i.e. F ∝ q₁q₂
F ∝ 1/r²
F ∝ q₁q₂/r²
F = kq₁q₂/r²
where k is proportionality constant k = 1/4π∈₀ = 8.9×10⁹
In this problem,
Given,
q₁ = 6.33×10⁻⁶ C
F = 0.115N
r = 1.44m
q₂ = ?
putting this values in the equation,
0.115 = 8.9×10⁹×6.33×10⁻⁶ ×q₂÷1.44²
q₂ = 4.23 μC.

1200 W, 2000 W, and 720 W devices will be operated on 220 V at the same time. Calculate the current through each device.
Answer:
I₁ = 5.45 A
I₂ = 9.1 A
I₃ = 3.27 A
Explanation:
Electrical power is defined as the product of current and displacement.
[tex]P = VI\\\\I = \frac{P}{V}[/tex]
where,
P = Power of Device
I = current passing through the device
V = voltage across the device = 220 V
FOR P₁ = 1200 W
[tex]I_1 = \frac{1200\ W}{220\ V}[/tex]
I₁ = 5.45 A
FOR P₂ = 2000 W
[tex]I_2 = \frac{2000\ W}{220\ V}[/tex]
I₂ = 9.1 A
FOR P₃ = 720 W
[tex]I_1 = \frac{720\ W}{220\ V}[/tex]
I₃ = 3.27 A
What is the rule you would write describing how light reflects off a mirror?
Answer: The angle of incidence equals the ray of reflection. So this law states that any ray of light that strikes an object will reflect off the object such that the striking or incident angle is identical to the reflecting angle (as measured from the normal).

Comparing Cells
i need to know a few things about the primary function and organelles present in..
protists cells
fungus cells
plant cells
and, animal cells
Answer:
Protists cells: ribosomes, mitochondria, and chloroplasts.
Fungus cells: cell walls, nuclei, mitochondria, endoplasmic reticulum, Golgi apparatus, endosomal vacuoles, various types of vesicles, and peroxisomes.
Plant cells: chloroplast, cell wall, plastids, and a large central vacuole.
Animal cells: nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles.
Answer:
1) Ribosomes: Are the organelles responsible for synthesizing all the proteins the protist will need
Mitochondria: which are the organelles responsible for turning food into energy the cell can use
Chloroplasts, which are the organelles that are able to capture sunlight
____________________________________________________________
2) Mitochondria: Developmental and morphogenetic switches such as hyphal differentiation and biofilm formation, adaptation to stress, cell wall biosynthesis and structure.
Endoplasmic reticulum: harbors several of the enzymes involved in the biosynthesis of ergosterol, an essential membrane component
Golgi apparatus: performs crucial functions in the sorting and processing of proteins destined for secretion
____________________________________________________________
3) Chloroplast: Allow plants to capture the energy of the Sun in energy-rich molecules and carries out the process of Photosynthesis.
Cell wall: The cell wall surrounds the plasma membrane of plant cells, providing structure and protects the plant from mechanical and osmotic stress.
Plastids: responsible for manufacturing and storing of food. These often contain pigments that are used in photosynthesis
Vacuole: Simply helps maintain water balance, usually large and takes up most of the space in a plant cell.
____________________________________________________________
4) Nucleus: Controls and monitors the activities of the cell and carries the genes, structures that contain the hereditary information for their offspring.
Mitochondria: Generates most of the chemical energy needed to power the cell's biochemical reactions.
Endoplasmic reticulum: Serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins.
Golgi apparatus: Helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
Vesicle: Transport vesicles help move materials, such as proteins and other molecules, from one part of a cell to another
Vacuole: Are generally small and help dispose waste products in the cell.
Ribosomes: Link together specific amino acids to form polypeptides and they export these to the cytoplasm.
If the work required to speed up a car from 11 km/h to 21 km/h is 6.0×103 J , what would be the work required to increase the car’s speed from 21 km/h to 33 km/h
Explanation:
We need convert the velocities first to m/s and we get the following:
v2 = 21 km/hr = 5.8 m/s
v1 = 11 km/hr = 3.1 m/s
We need to find the mass of the car also for later use do using the work-energy theorem:
[tex]delta \: w = \frac{1}{2} m(v \frac{2}{2} - v\frac{2}{1} )[/tex]
6.0x10^3 J = (0.5) m [(5.8)^2 - (3.1)^2]
or
m = 499.4 kg
Now we determine work needed delta W to change its velocity from 21 km/hr to 33 km/hr
v2 = 33 km/hr = 9.2 m/s
v1 = 21 km/hr = 5.8 m/s
delta W = (0.5)(499.4)[(9.2)^2 - (5.8)^2]
= 1.3 x 10^4 J

The speed of a wave with a frequency of 2 Hz (2/s), an amplitude of 3 m, and a wavelength of 10 m is
options:
0.2 m/s.
12 m/s.
5 m/s.
20 m/s.
Answer:
5 m/s
Explanation:
your welcome
The speed of a wave equals to Wavelength and Frequency. The SI unit of speed of wave is m/s. Thus, option D is correct.
What is speed of wave?The speed of wave is distance travelled by the wave in given time. It is related to both wavelength and frequency. Wavelength is measured in meters and frequency in hertz.
From the givens:
Frequency(f) = 2 Hz.
Wavelength(λ) = 10m.
Amplitude = 3m ( Amplitude does not affect the speed of wave)
Speed (v) = λ × f
= 10 × 2
= 20 m/s.
Therefore, the speed of the wave is 20 m/s. Hence, Option D is correct.

6. An excited dog runs full-speed toward his owner who has just returned home from
school. If he runs north along their driveway for a distance of 45 m and takes 5.2 s to get
there, what is his average velocity?
Please answer in comments with work !!:)
Answer:
v = 8.65 m/s
Explanation:
Given that,
Distance covered by the doge, d = 45 m
Time taken, t = 5.2 s
We need to find its average speed. The total distance covered divided by the total time taken is called the average speed of an object. So,
[tex]v=\dfrac{45\ m}{5.2\ s}\\\\=8.65\ m/s[/tex]
So, the average speed is 8.65 m/s.
