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.

Explanation:
When rutherford bombarded thin gold foil with a-particles,he found that some a-particles were deflected through large angles. Which statement explains this deflection?
Answer:
the nucleus of the atom you have conserved almost all its mass in a very small volume
Explanation:
In Rutherforf's experiment, most alpha particles had few deflections, eg a few of them were deflected at small angles, a much smaller number deflected at large angles, and very few were deflected.
The explanation that I found for this is that if all the mass and the positive charge of the atom is in a small volume, they could specifically calculate this the relationship of the volumes,
V_atom / V_nucleo = 10⁴
Therefore, the phrase that explains the observing phenomenon is that the nucleus of the atom has concentrated almost all its mass, very small emolument and in that same volume is all the positive charge of the atoms.
In summary, the phrase that describes the process is:
the nucleus of the atom you have conserved almost all its mass in a very small volume

Radioactive decay
Half-life
Radiometric dating
2. How does radioactivity affect Earth’s interior?
Answer:
Radioactive decay: is the process by which an unstable atomic nucleus loses energy by radiation.
Half-life: in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive material to decrease by one-half.
Radiometric dating: is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.

Which best explains how Selena can correct her error? She can change the magnets so like poles are facing each other. She can change the arrows so they show current traveling in opposite directions on the sides of the loop. She can change the arrows so they show the magnetic field reversing direction between the magnets. She can change the magnetic poles so they are both on one side of the loop.
Complete question is;
Selena drew a diagram to show how current moves in a loop of wire that is placed between two magnets. At top left a piece of magnet labeled N and at top right a piece labeled S. Between these a square coil of wire with green arrows at its ends away from the magnets pointing away from the magnets. Red arrows point from N to S. Which best explains how Selena can correct her error?
A) She can change the magnets so like poles are facing each other.
B) She can change the arrows so they show current traveling in opposite directions on the sides of the loop.
C) She can change the arrows so they show the magnetic field reversing direction between the magnets.
D) She can change the magnetic poles so they are both on one side of the loop.
Answer:
B) She can change the arrows so they show current traveling in opposite directions on the sides of the loop.

A negative charge of -0.00040 C and a positive charge of 0.00092 C are separated by 0.4 m. What is the force between the two charges?
Answer:
20654 N
Explanation:
Applying
F = kqq'/r²........... equation 1
Where F = Force between the charge, q = First charge, q' = second charge, r = distance betweeen the charge, k = coulomb's constant.
From the question,
Given: q = -0.0004 C, q' = 0.00092 C, r = 0.4 m
Constanr: k = 8.98×10⁹ Nm²/C²
Substitute these values into equation 1
F = ( -0.0004×0.00092×8.98×10⁹)/(0.4²)
F = (3.30464×10³)/0.16
F = (3304.64)/0.16
F = 20654 N
Hence the force between the charges is 20654 N

Answer:
1.) The 1ˢᵗ three term is (-32), (-7) and 18
2.) The 1ˢᵗ three term is 127, 106 and 85
Step-by-step explanation:
1.)Here,
First Term = a₁ = - 32
Common Difference = (d) = 25
Now, For 1ˢᵗ three term,
n = 1
a₁ = - 32
n = 2
aₙ = a + (n - 1)d
a₂ = (-32) + (2 - 1) × 25
a₂ = (-32) + 1 × 25
a₂ = (-32) + 25
a₂ = -7
n = 3
aₙ = a + (n - 1)d
a₃ = (-32) + (3 - 1) × 25
a₃ = (-32) + 2 × 25
a₃ = (-32) + 50
a₃ = 18
Thus, The 1ˢᵗ three term is (-32), (-7) and 18
2.)Here,
First Term = a₁ = 127
Common Difference = (d) = -21
Now, For 1ˢᵗ three term,
n = 1
a₁ = 127
n = 2
aₙ = a + (n - 1)d
a₂ = 127 + (2 - 1) × (-21)
a₂ = 127 + 1 × (-21)
a₂ = 127 - 21
a₂ = 106
n = 3
aₙ = a + (n - 1)d
a₃ = 127 + (3 - 1) × (-21)
a₃ = 127 + 2 × (-21)
a₃ = 127 - 42
a₃ = 85
Thus, The 1ˢᵗ three term is 127, 106 and 85

Un muelle se alarga 30 centímetros cuando ejercemos sobre el una fuerza de 24 N a) calcula el valor de la constante elástica del muelle b) calcula el alargamiento del muelle al aplicar una fuerza de 60 N
Answer:
(a) k = 80 N/m (b) x = 75 cm
Explanation:
The question says that, "A spring is elongated 30 centimeters when we exert a force of 24 N on it a) calculate the value of the spring constant b) calculate the elongation of the spring when applying a force of 60 N"
Given that,
Force exerted on the spring, F = 24 N
Elongation in the spring, k = 30 cm =0.3 m
(a) We know that, the force on the spring is given by :
F = kx
Where
k is spring constant
So,
[tex]k=\dfrac{F}{x}\\\\k=\dfrac{24}{0.3}\\\\k=80\ N/m[/tex]
(b) When F = 60 N,
[tex]x=\dfrac{F}{k}\\\\x=\dfrac{60}{80}\\\\x=0.75\ m\\\\x=75\ cm[/tex]
Hence, this is the required solution.

Answer:
Awareness was selected because it was beneficial to organisms in particular environments.
Explanation:
Based on the article, natural selection is a phenomenon that recognizes and allows traits that are useful to an organism and that would be favorable for it to be passed from one generation to another.
Natural selection marked awareness as a useful trait that would be beneficial for organisms because it helped them adapt well to the particular environments that they found themselves. For example, this ability helped an organism to be able to recognize where it could get food and light in its environment.

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
