Which of the following best describes the 1957 events at Central High School in Little Rock, Arkansas? Governor Faubus resisted the school’s integration with National Guard troops, and President Eisenhower sent federal troops to enforce integration. Under Governor Faubus, Little Rock police first fought, then enforced, the order to integrate the school. President Eisenhower sent National Guard troops to resist the school’s integration, but Governor Faubus obtained a court order to dismiss them. President Eisenhower and Governor Faubus worked together to make the integration process run as smoothly as possible.

[ad_1]

The correct answer is  Governor Faubus resisted the school’s integration with National Guard troops, and President Eisenhower sent federal troops to enforce integration.

After the Supreme Court case Brown vs. Board of Education (1954) the federal government called for the desegregation of schools all across America. This included Central High School. Central High School was previously an all white school. After Brown vs. Board of Education ruled segregated schools illegal, 9 black students enrolled at Central High School. These individuals would be known as the Little Rock 9.

After enrolling, these students tried to attend Central High School but were kept out by the national guard troops. This was due to Governor Fabius’s disagreement with integrating white and black schools. However, President Eisenhower enforced the federal ruling by sending in federal troops to enforce the new ruling, allowing black and white students to attend the same school.

Think about an igneous rock at the top of a mountain. If this rock went through the whole rock cycle, number the steps that would follow. 1. Step 1 Regolith is dumped into some type of reservoir, usually water, by deposition. 2. Step 2 Metamorphic rock begins to melt back into magma. 3. Step 3 Regolith is transported or eroded by rain or wind. 4. Step 4 Rock is broken down into regolith by weathering. 5. Step 5 Layers deposited begin to compact and cement together to form sedimentary rock. 6. Step 6 Sedimentary rock is buried deeper into the earth’s crust. The intense heat and pressure begins metamorphism and the rock turns into metamorphic rock. 7. Step 7 Magma is resurfaced from volcanic activity, cools, and becomes igneous rock.

[ad_1]

Answer:

The correct sequence according to the question is steps- 4→1→3→5→6→2→7.

Explanation:

The given steps show that how the rocks are recycled from one form to another form due to certain factors like weathering over geological time scale which was explained by James Hutton and he termed this concept as the rock cycle.

The steps of the rock cycle in sequence according to the question are:

1.  Breakdown of rock by weathering into regolith- step 4

2.  Dumping and deposition of regolith in a reservoir- step  1

3.  Erosion and transportation of regolith by rain or wind- step  3

4. Cementing of the deposited layer to form sedimentary rock- step  5

5. Conversion of sedimentary rock to a metamorphic rock due to intense heat and pressure- step 6

6. Conversion of  metamorphic rocks to magma due to the melting of metamorphic rocks-
step 2

7. Conversion of magma to igneous rocks due to volcanic activities and cooling of magma-  step 7

Therefore sequence according to the question is steps- 4→1→3→5→6→2→7 is correct.

A student used a yardstick to model the displacement of rock at a fault during an earthquake. The student bent the yardstick without breaking it and then let it go. What process did the student show? A. A moment magnitude vibration B. Elastic rebound C. Isostasy D. The formation of a new fault

[ad_1]

Answered by answersmine AT 22/10/2019 – 03:54 AM

I think the correct answer would be B. The process of elastic rebound is being shown by the student. It is a theory that is used to explain earthquakes. It focuses on how energy is being spread in times of earthquakes. As the rocks on the fault experiences shift and force, these rocks would be accumulating energy causing it to deform reaching the internal strength and eventually exceeding it. At that moment, a rapid motion would happen along the fault, which releases the energy, then the rocks would go back to its original shape or the undeformed state. This theory is the first theory that sufficiently was able to explain earthquakes.

In which of the following places would you LEAST likely find a metamorphic rock?

[ad_1]

Answer:

1. DNA

2. Prokariotic.

3. Crossing over.

4. Maple tree

5. Primary producers.

6. DIAGRAM NOT SHOWN

7. Lipids.

8. A

Explanation:

1. DNA is the macromolecule responsible for carrying the herederitary information of all cells, and even some viruses, with the exception of retroviruses.

2. Prokariotic cells (eubacteria and archeas) are cosmopolite, and lacks a membrane defined nucleus.

3. Crossing over.

During meiosis, homolog chromosomes pair and exchange genetic material, is also known as genetic recombination. This makes the chromosomes inherited not exactly equal to the corresponding from our fathers, or grandfathers.

4. Maple tree belongs to the clade Angiosperms: flowering plants, which produce seeds. Moss is a flowerless plant, this does not produce seeds. Lichen are composed from algae and cyanobacteria (so, not plants). Mushrooms are not plants.

5. Primary producers, such as bacteria and algae, can make organic  molecules from an abiotic source of energy.

6. DIAGRAM NOT SHOWN

7. Lipids are the main component of all biological membranes. In animals, specially cholesterols prevents the membrane from freezing, due its molecular structure. Tryglicerids, for example, provides besides thermal insulation, energy storage, filling space for keeping the organs together, among other functions.

8. The phosphorous is very slow, since it requires the extraction from rocks, starting from metereological processes (rain, erosion), Once in the soil, bacteria, fungi, plants and animals start to absorb it.

If you were to drop a rock from a tall building, assuming that it had not yet hit the ground, and neglecting air resistance, how far would it have fallen (in m) after 2 s? (g = 10 m/s2) 20.0

[ad_1]

The gravitational force Fg between two objects is given by the equation:

Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies. 

Due to the gravitational attraction the pencil and the eraser will attract if we there is no friction on the surface. 

m₁=10 g=0.01 kg is the mass of the pencil
m₂=20 g=0.02 kg is the mass of the eraser
r=2.5 cm = 0.025 m

First we calculate the Fg:

Fg={(6.67*10^-11)*0.01*0.02}/(0.025²)=2.1344*10^-11 N

To get the velocity v of the pencil:

v²=2as, where a is the acceleration of the pencil and s is the path. In our case s=r so we can write:

v²=2ar

a=Fg/m₁= 2.133*10^-9 m/s²

v²=2*(2.133*10^-9)*0.025=1.0665*10^-10

v=√(1.0665*10^-10)=1.0327*10^-5 m/s

We have the velocity and the acceleration, so we can calculate the time t with the equation:

t=v/a=(1.0327*10^-5)/(2.133*10^-9)=4841.6 s

1 hour has 3600 s so when we divide time t in seconds by 3600 we get time T in hours:

T=t/3600=4841.6/3600=1.3449 h. 

So the time for the pencil and eraser to touch is T=1.3449 hours. 

Also time T can be expressed like T= 1h and 20 mins and 41.64 s

A rock is stuck deep in the dirt. When you pull on the rock to remove it, what type of force are you exerting? A.Compression B.Strong nuclear force C.Tension D.Air resistance

[ad_1]

The equation for how temperature changes the resistance R is: 

R=R₀(1+α(T-T₀)), where R₀ is the resistance at T₀=20°C, T is the temperature for which we want to calculate the resistance and α is the temperature coefficient for resistance. 

The resistance of the copper wire increases by 18% or by 0.18, so the new value for the resistance is R=1.18*R₀.

T₀=20°C
=0.0068
R=1.18*R₀

Now we need to input that into the equation for resistance change and solve for temperature T.  

1.18R₀=R₀(1+α(T-20)), R₀ cancels out,

1.18=1+α(T-20),

1.18-1=α(T-20), we divide by α,

0.18/α=T-20, we put 20 on the left side,

26.47+20=T

T=46.47°C

So the temperature on which the resistance of copper wire will increase by 18% is T=46.47°C.

Which type of rock is especially likely to form caves

[ad_1]

The correct answer is – Principle of superposition.

In the geology, the principle of superposition is very often used for the determining of the age of the rocks, but only if the layers are undisturbed. This principle suggests that if the rock layers have not been disturbed, than the layers of rocks are order in a manner from youngest to oldest, top to bottom viewed.

This is a very useful and easy way for determining the age of the rocks, since the new rock layers are coming on top of the older ones, but also, very often in nature that is not the case. The rocks are not always ordered by age, because very often there’s disturbance to them, and that can be sideways pressure, pressure from bellow, intrusion, and they all will manage to mix up the layers.

First thing to do, you need the specific heats of the substances in the system and the heat of fusion of ice. From literature, they are as follows:

Copper = 0.385 kJ/kg.°C
Lead = 0.127 kJ/kg.°C
Water = 4.181 kJ/kg.°C
heat of fusion of ice = 333.6 kJ/kg 

Next, we let the final temperature be T in units of °C. 

The ice and water are in equilibrium thermally, so the temperature should be 0°C. By the law of conservation of energy,

Heat lost = Heat gained

Heat lost by lead = [ 0.75 (0.127 ) (255-T) ]kJ 

Heat from the melting ice = [(0.018 ) 333.6 ]kJ 
Heat gained from 0 to T = [(4.181) (T) (0.16 + 0.018)] kJ 
Heat to raise the calorimeter to T = 0.0385T]  kJ

Equating heat lost and heat gain, we can calculate for T. Therefore,

(0.75) (0.127) (255-T) = 6.0048 + 0.7442T + 0.0385T
T = 20.83 C

Answer: The percent yield of NO is 71.43 %.

Explanation:

To calculate the number of moles, we use the equation:

text{Number of moles}=frac{text{Given mass}}{text{Molar mass}}      …..(1)

Given mass of ammonia = 9.5 g

Molar mass of ammonia = 17 g/mol

Putting values in equation 1, we get:

text{Moles of ammonia}=frac{9.5g}{17g/mol}=0.56mol

The given chemical equation follows:

4NH_3+5O_2rightarrow 4NO+6H_2O

By Stoichiometry of the reaction:

4 moles of ammonia produces 4 moles of NO

So, 0.56 moles of ammonia will produce frac{4}{4}times 0.56=0.56mol of NO

Now, calculating the mass of NO from equation 1, we get:

Molar mass of NO = 30 g/mol

Moles of NO = 0.56 moles

Putting values in equation 1, we get:

0.56mol=frac{text{Mass of NO}}{30g/mol}\\text{Mass of NO}=(0.56moltimes 30g/mol)=16.8g

  • To calculate the percentage yield of NO, we use the equation:

%text{ yield}=frac{text{Experimental yield}}{text{Theoretical yield}}times 100

Experimental yield of NO = 12.0 g

Theoretical yield of NO = 16.8 g

Putting values in above equation, we get:

%text{ yield of NO}=frac{12.0g}{16.8g}times 100\\% text{yield of NO}=71.43%

Hence, the percent yield of NO is 71.43 %.

The acceleration of the object if

a. The force is doubled → a = 16 m/s²

b. The object’s mass is doubled → a = 4 m/s²

c. The force and the object’s mass are both doubled → a = 8 m/s²

Further explanation

Newton’s second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.

large {boxed {F = ma}

F = Force ( Newton )

m = Object’s Mass ( kg )

a = Acceleration ( m )

Let us now tackle the problem!

Given:

a₁ = 8 m/s²

Question A:

The force is doubled → F₂ = 2F₁

F_1 : F_2 = ma_1 : ma_2

F_1 : F_2 = a_1 : a_2

F_1 : 2F_1 = 8 : a_2

1 : 2 = 8 : a_2

a_2 = 8 times 2

boxed {a_2 = 16 ~ m/s^2}

Question B:

The object’s mass is doubled → m₂ = 2m₁

F_1 : F_2 = m_1a_1 : m_2a_2

F_1 : F_1 = m_1a_1 : 2m_1a_2

1 : 1 = 1a_1 : 2a_2

1 : 1 = 1(8) : 2a_2

2a_2 = 8

a_2 = 8 div 2

boxed {a_2 = 4 ~ m/s^2}

Question C:

The force and the object’s mass are both doubled → F₂ = 2F₁ , m₂ = 2m₁

F_1 : F_2 = m_1a_1 : m_2a_2

F_1 : 2F_1 = m_1a_1 : 2m_1a_2

1 : 2 = a_1 : 2a_2

1 : 2 = 8 : 2a_2

2a_2 = 8 times 2

2a_2 = 16

Answer: by adding or removing neutrons

Explanation: Isotopes are the elements which have same atomic number but different mass number.

Atomic number is the number of electrons or number of protons in a neutral atom.Mass number is the sum of number of protons and the number of neutrons.

Thus changing the number of electrons would lead to formation of ions of the same element, change in protons would change the atomic number.

The mass number is changed by adding or removing neutrons.

For example, _6^{12}textrm{C} and  _6^{14}textrm{C} are isotopes of carbon element, containing 6 electrons and 6 protons each. The number of neutrons are 6 and 7 respectively.
