Read the excerpt from President Eisenhower’s State of the Union address on February 2, 1953. A cardinal ideal in this heritage we cherish is the equality of rights of all citizens of every race and color and creed. We know that discrimination against minorities persists despite our allegiance to this ideal. Such discrimination—confined to no one section of the Nation—is but the outward testimony to the persistence of distrust and of fear in the hearts of men. This fact makes all the more vital the fighting of these wrongs by each individual, in every station of life, in his every deed . . . I propose to use whatever authority exists in the office of the President to end segregation in the District of Columbia, including the Federal Government, and any segregation in the Armed Forces. What is the president’s purpose for including these details? to inform his listeners about laws in the District of Columbia to inform his listeners about the work of the US military to persuade his listeners of the importance of equal rights to persuade his listeners to vote for him for president

[ad_1]

to persuade his listeners of the importance of equal rights

The excerpt begins with the statement about cherishing equal rights of all citizens. It then talks about how discrimination is still occurring. He then pledges to end segregation in all places where he has the power to do so: Washington D.C., Federal Government, and the Armed Forces. The excerpt does not include and laws, work the military has done, or calls for presidential votes.

Which statement best describes the difference between strong nuclear forces and weak nuclear forces? a) Weak nuclear forces hold protons and neutrons together; strong nuclear forces hold electrons in their shells. b) Strong nuclear forces are responsible for holding electrons in bonds; weak nuclear forces are involved when the bonds break. c) Weak nuclear forces hold the atoms’ nucleus together; strong nuclear forces tear them apart. d) Strong nuclear forces are responsible for holding together the nucleus of an atom; weak nuclear forces are involved when certain types of atoms break down.

[ad_1]

There are four types of fundamental forces in nature.These are named as gravitational force,electromagnetic force,strong nuclear force and weak nuclear force.

As per the question we have to understand the role of strong nuclear force and weak nuclear force.

An atom consists of a nucleus surrounded by extra nuclear part consisting of electrons in various orbits.The nucleus contains two basic particles called protons and neutrons .Protons are positively charged while neutrons are neutral.Protons being positively charged will impart repulsive force on each other and may come out of the nucleus.But the nucleus is stable.That is due to the strong nuclear force.

Strong nuclear force is a spin dependent and charge independent force which comes into existence due to the mutual interaction of gluons which binds the protons and neutrons .Hence it is attractive in nature.It’s 100 times more stronger than electromagnetic force also.

Weak nuclear force comes into existence during radio -active decay .This force is due to the exchange of ‘ w’ and ‘z’ bosons[the particles like protons and neutrons having integral or zero spin] which are heavier in nature.The role of it is to change protons into neutrons and vice versa.Its a short range force.

Hence the option D is right.

Karl Marx developed the economic theory of communism.

Further Explanation:

One of Karl Marx’s most famous contributions came in his book the Communist Manifesto. This book explained Mark’s views on government, the economy, and ultimately lead to the creation of communism as an idea.

A communism system is one that is economic and political in nature. In this system, the government would control the means of production, the distribution of goods and resources, and would overall have significant control over society. This system of communism is the opposite of the capitalist/democratic system used in America today. These two ideologies would clash during the mid 20th century in what is now known as the Cold War.

Marx’s ideas were based on his observations of the world around him. He felt that the mistreatment of labor by industry and private corporations would ultimately lead to an uprising by angry laborers all over the world.

Here are the following effects of loose money and tight
money policies on the actions being listed.

A. A loose money policy
is usually implemented as an effort to encourage economic growth.
This can lead to inflation when uncontrolled. The effects are:

1. Borrowing becomes easy

2. Consumer buys more

3. Since more people are willing to buy,
businesses expand

4. Employment rate increases due to
expansion of businesses

5. Since more people are employed, thus
production also increases

 

B. A tight money policy is a course of action to restrict spending
in an economy that is growing too quickly or to hold back inflation when it is
rising too fast. This can lead to recession when uncontrolled. The
effects are:

1. Borrowing becomes difficult

2. Consumer buys less

3. Since people don’t have a lot of
money, business don’t expand

4. Unemployment rate increases due to businesses
slowing down

5. Production decreases

A car in dynamic equilibrium is acted upon by the following forces: force due to gravity= -9000 newtons Force due to friction = -250 newtons Forward force exerted by engine = 250 newtons. What is the value of the force exerted by the ground on the car?

[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

Natural Forces Affecting the Driver In one or more complete sentences, explain how natural laws apply to the following scenarios: How does inertia affect a person who is not wearing a seatbelt during a collision? How does kinetic energy affect the stopping distance of a vehicle traveling at 30 mph compared to the same vehicle traveling at 60 mph? How does kinetic energy affect the stopping distance of a small vehicle compared to a large vehicle? Keeping in mind the kinetic energy of a moving vehicle, how can a driver best prepare to enter sharp curves in the roadway? Using information about natural laws, explain why some car crashes produce minor injuries and others produce catastrophic injuries. Signs, Signals, and Pavement Markings Imagine you are taking a road trip! Select a destination and navigate the trip. Answer the following questions in one or more complete sentences: Where will you go on your trip? You approach a railroad crossing with a cross buck sign that has no lights or gates. What should you do? You arrive at an intersection with traffic lights that are not working because of a power outage. What do you do? There is a flashing yellow light at the intersection you are approaching. What does the flashing yellow light indicate, and what should you do to safely navigate this intersection? On the road you are traveling, the pavement markings change from broken white lines to solid white lines between the lanes of traffic. What does the line change mean? After an hour on the expressway, your passengers need to use the restroom and they want to get some food. As you approach the next exit, what color sign will you look for, and what type of information would you expect to see on that sign? When you take the exit ramp off the expressway and merge onto the next road, you see yellow lines dividing the roadway. What do the yellow lines tell you about the traffic flow?

[ad_1]

Natural Forces Affecting the Driver:

1. While the car stops, the person continues moving the way that the car were moving and then hits the obstacle in the car or the person can be thrown out of the vehicle. If the person wears belt, he will stop moving with the vehicle and won’t hit the obstacle.

2. We count approximate kinetic energy using the formula K = v^2. So the vehicle which is moving at 30 mph will have four times less kinetic energy than vehicle which is moving at 60 mph. If they have the same road conditions, the breaking distance will be four times as great for the car moving twice as fast.

3. Kinetic energy depends on object’s mass and velocity and it has direct relationship with the stopping distance. The lesser mass of the vehicle = the lesser kinetic energy and lesser stopping distance. => If both vehicles have the same velocity, then small vehicle has lesser kinetic energy than large vehicle.

4. We know that kinetic energy has this relationship with velocity K = v^2. So the best way to prepare to enter sharp curves in the roadway is to lower the speed. The most appropriate speed is 20-30 mph, but it depends on road conditions and car’s breaks condition.

5. Car crashes can happen with everyone so the best way is to be prepared. First the driver should wear a seatbelt while he’s driving. He should check his tires and breaks condition regularly. And also it’s important to slow down the vehicle while entering sharp curves. Without following these rules, the driver can get catastrophic injuries in a car crash.

Signs, Signals, and Pavement Markings: 

1. It doesn’t matter where you go. All you need is to learn highway code. It’s very different to know the meanings of every road sign. Also, it’s necessary to check your car’s conditions and you should take some spare parts for your car in case of accidents. So wherever you go, it’s important to be prepared.

2. You should stop before crossing and take few minutes to make sure there is no train approaching. If there is no train approaching, you can pass a railroad crossing. If you see approaching train, you should wait until it will pass a railroad crossing.

3. You should stop before the lights and wait to check the traffic movement and signs. Make sure that everything is safe and pass the intersection. Don’t move fast to avoid accidents.

4. Flashing yellow light means that it’s not necessary to stop but you should to pay attention on the traffic movement. So it would be better to yield before the lights and make sure if it’s safe to move. After that you can cross the intersection.

5. The line change means that the lane changes and you can’t cross solid lines. Pay more attention on road marking because it shows how you should behave on the road or highway.

6. As you approach the next exit and  your passengers need to use the restroom and get some food, you should look for green signs which indicate food and rest stops. You should to slow down if you don’t want to skip the sign.

7. When you take the exit ramp off the expressway and merge onto the next road, you see yellow lines dividing the roadway which indicates that there is oncoming traffic and this is a two-way highway.

Select the statement that best describes how the forces relate.A. The object on which they are acting and the distance to that object determines the amount of force.B. nuclear and magnetic forces are different because magnetic forces are associated with unmoving charges, and weak nuclear forces are associated with moving charges.C. All forces are related to the mass of the object on which they are acting.The larger the mass, the weaker the forces become. D. Magnetic and electrical forces are similar because they are both related to the interactions between charged particles.

[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

Which of these statements best proved that electromagnetic forces are weaker than strong nuclear forces?

[ad_1]

Answer:

The incorrect statement is option D. Digestive tracts have two openings, which allows food to move in two directions.

Explanation:

The digestive system is a long twisted tube from the mouth to the anus with a series of accessory organs connected to it. This long twisted continuous tube having two openings, mouth and the anus, called the digestive tract that allows food to move in one direction only (mouth to anus).

In the digestive tract, food enters from the mouth and food passing through pharynx, esophagus, stomach, small intestine, and large intestine. The indigestible food or waste eliminated through the anus.

So, the digestive tract allows food to move in one direction only.

Thus, incorrect option would be option D.

Liquids and solids are referred to as “condensed phases” because the attractive forces are?

[ad_1]

25) Answer is: less metallic and more nonmetallic.

Electronegativity increases from left to right across a period, atoms have tendency to attract electrons.

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.

26) Answer is: radioisotope.

Radioisotope has an unstable atomic nucleus and emit energy and particles when it changes to a more stable form.

Francium (Fr) is element with atomic number 87 (87 protons and 87 electrons).

27) Answer is: boils.

Boiling is the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.

The Celsius scale was based on 0°C for the freezing point of water and 100°C for the boiling point of water at 1 atm pressure.

28) Answer is: endothermic.

There are two types of reaction:  

1) endothermic reaction (chemical reaction that absorbs more energy than it releases, ΔH>0).

2) exothermic reaction (chemical reaction that releases more energy than it absorbs).  

For example, the breakdown of ozone is an endothermic process. Ozone has lower energy than molecular oxygen (O₂) and oxygen atom, so ozone need energy to break bond between oxygen atoms.  

29) Answer is: kinetic.

The average kinetic energy of molecules depends on the temperature.  

As temperature increases, molecules gain more energy from surrounding and move faster.  

Kinetic energy (standard unit is the joule J) depends on speed of the molecule.  

Solid gains kinetic energy to become a liquid and then becomes a gas.

30) Answer is: alpha particles.

This was famous Rutherford’s Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles.

Rutherford observed the deflection of alpha particles on the photographic film.  

Alpha particles are helium atom particles, consist of two protons and two neutrons.  

According to Rutherford model of the atom: atoms have their charge concentrated in a very small nucleus.  

31) Answer is: highest.

For example, calcium oxide.

Calcium oxide (CaO) has ionic bonds between calcium cations (Ca²⁺) and oxygen anions (O²⁻).

Because it has strong ionic bonds, it has high melting point (around 2600°C).

Ionic bond is the electrostatic attraction between oppositely charged ions (cations and anions).

32) Answer is: a scientific model.

A scientific model is a representation of an idea, an object, a process or a system that is used to describe and explain phenomena that cannot be experienced directly.

33) Answer is: the superscript is mass number and the subscript is atomic number.

Atomic number(Z) is the number of protons, which is characteristic of a chemical element..

Mass number (A) is the total number of protons and neutrons in a nucleus.

Answer:

1) Water has very high specific heat.

2) It expands when it freezes

3) ability to dissolve in ionic substances

4) Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.

Explanation:

1) Water molecules due to their high specific heat , undergo relatively less increase in temperature after absorbing heat. So they prevent their adjoining area to experience sharp increase in temperature.

2) Water is an example which expands on freezing. In it , large spaces are left between molecules when it cools. It happens because hydrogen bonds prevent any two molecules to come very close thereby  creating gaps. This gap is filled up when ice melts , which results in overall reduction in volume of water.

3) Uneven distribution of charge results in water molecules becoming polar in nature . A polar substance  can be dissolved in polar solvents only.

4) It is due to property of surface tension. Property  of surface tension results due to molecules of water near the surface experiencing a  net downward  force due to hydrogen bonds . It is due to fewer hydrogen bonds made by them.

The answer to the question: Although she does not have a background in law, she hopes to land the job because of the:___, would be: Screening effect.

Explanation:

The screening effect is a theory that is used by companies and recruiters in order to effectively select and screen the best candidates for a specific position, even if these candidates may not fulfill all the requirements for that position. What the theory does is propose that candidates who have completed a college degree show their capacities, even if these are not specifically related to an expected topic, by simply achieving this goal, and are therefore worthy to be taken into account for selection. In the case of Tracy, she has not just fulfilled the part of the theory of finishing her degree, but she has overachieved by obtaining the best degrees in topics that are related to a job as a legal assistant. The screening effect will allow recruiters to see Tracy´s records and take her into account, even if she has never had any legal experience, due to her achievements in related topics.

[ad_1]

The Reformation actually started after Columbus’s landing in North America. 

Treaty of Tordesillas in 1494 was forced on Spain and Portugal by the Pope. The Pope basically said that all lands in the New World belonged to Spain and all new non-Christian lands in the Eastern Hemisphere belong to Portugal. No other Catholic countries can do anything in those areas without the approval of the owner. 

The pope basically drew two lines on the globe setting the border. The western line started at the north pole cut half way through Greenland and ended at the south pole. The new world was everything to the west. Problem is that it ran through a chunk of Brazil which is why Brazil is an ex-Portuguese colony. 

The Eastern line starts at the North Pole runs through siberia, through the pacific just west of Japan, and cuts Australia in half. Of course, Australia hadn’t been discovered yet. Everything to the the east of this line is the new world. 

Obviously, this treaty didn’t hold up well, but the reformation gave the protestant countries an excuse to explore the new world since they didn’t have to take orders from the Pope. Even so, France, a catholic country, ignored it too. 

Really, the only country that was effected by the reformation in the exploration of the Americas was England. All the other countries, changed their religion once and then went to war with the nearest catholic country. Sweden became Lutheran and stayed that way. The Dutch Republic became Calvinists and stayed that way. 

England kept switching. First it was Catholic. Then, Henry VIII made it protestant. Then, Henry’s daughter Mary I made it catholic again. Henry’s other daughter Elizabeth I (with the two hit movies) made it Protestant again. 

Years latter, Oliver Cromwell over through the monarchy, executed the King Charles I, and established a Protestant fundamentalist religious military dictatorship. He outlawed drinking,smoking, gambling, theater, dirty books, sports, prostitution, and anything generally fun. He would have made Saudi Arabia proud. Basically, all you could do is work, pray, and die. Sex was allowed for creating children, but you couldn’t enjoy it. 

When Cromwell died, the people of England said enough was enough and brought back the King. Charles II kicked out the fundamentalists and brought back drinking, smoking, gambling, dirty books, sports, prostitution, and having fun during sex. Incidentally, those were also all his hobbies. 

This brings us to the famous Pilgrims. They were part of Cromwell’s crowd. They kept agitating a return to the no-fun policy. They annoyed everybody. They weren’t persecuted for practicing their religion, they were persecuted because they kept trying to force their religion on everyone else. Sort of like Southern Baptists. 

Charles II was the most easy going monarch in British history. Do realize how annoying you have to be to get him to throw you out. 

Charles’s brother James II was obsessed with turning Great Britain catholic again. After four years of trying, they kicked him and his followers out.

Question 2(Multiple Choice Worth 2 points) A scientist discovers a new substance. The molecules of the substance form hydrogen bonds with each other. When the molecules lose a lot of energy, the hydrogen bonds hold them relatively far apart. Based on this information, what can the scientist infer about the substance? It expands when it freezes. It is highly colored. It exists only as a gas. It does not dissolve ionic compounds. Question 3(Multiple Choice Worth 2 points) Which of the following properties of water is due primarily to the uneven distribution of charge between the hydrogen and oxygen atoms? its color its taste its ability to dissolve ionic substances its ability to produce buoyant forces Question 4(Multiple Choice Worth 2 points) A drop of water placed on a smooth, dry surface will form a dome-shaped droplet instead of flowing outward in different directions. Which of these best explains this observation? The bonds between hydrogen and oxygen atoms are very strong. The electrons in the atoms attract the electrons in the other atoms. Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid. Water molecules near the surface produce more buoyant force than water molecules within the liquid.

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

This problem is to apply Roult’s Law.

Roult’s Law states that the vapor pressure, p, of a solution of a non-volatile solute is equal to the vapor pressure of the pure solvent, Po solv, times the mole fraction of the solvent, Xsolv

p = Xsolv * Po sol

X solv = number of moles of solvent / number of moles of solution

The solvent is water and the solute (not volatile) is glycerin.

Number of moles = mass in grams / molar mass

mass of water = 132 ml * 1 g/ml = 132 g

molar mass of water = 18 g/mol

=> number of moles of water = 132 g / 18 g/mol = 7.33333 mol

mass of glycerin = 27.2 g

molar mass of glycerin:, C3H8O3: 3 * 12 g/mol + 8 * 1 g/mol + 3*16 g/mol = 92 g/mol

number of moles of glycerin = 27.2g / 92 g/mol = 0.29565

total number of moles = 7.33333 moles + 0.29565 moles = 7.62898 moles

=> X solv = 7.33333 / 7.62898 = 0.96125

=> p = 0.96125 * 31.8 torr ≈ 30.57 torr ≈ 30.6 torr.

Answer: 30.6 torr

Answer:    Joshua is correct

Explanation:  Animals, however well preserved and bred in conditions that are not in nature, that is, not in their natural habitat, animals still retain the animal instinct. Thus, young animals in the wild can be met daily, except for members of their species, and members of all other species, including predators, as well as humans. This means that in the natural environment, young animals can find themselves in a variety of dangers on a daily basis, but not only that. In this way young animals develop their ability to survive, escape from predators, manage, and develop their hunting skills, etc. All this is essential for socialization because according to all these developed skills and abilities their socialization depends. To deny any of the conditions prevailing in the wild means to deny the development of any skill or instinct, to deny proper socialization.
