C. someone who believes the kings power comes from the military.

Knights, were armored military units, sometimes on horses that are usually in an army to help protect their leader. IF a king doesn’t have the support of troops, he literally cannot reign. So you will need the militaries help

## Read the following excerpt taken from the US Supreme Court case Plessy v. Ferguson (1896). The case coming on for a hearing before the Supreme Court, that court was of opinion that the law under which the prosecution had was constitutional, and denied the relief prayed for by the petitioner. Ex parte Plessy, 45 La.Ann. 80. Whereupon petitioner prayed for a writ of error from this court, which was allowed by the Chief Justice of the Supreme Court of Louisiana. MR. JUSTICE BROWN, after stating the case, delivered the opinion of the court. This case turns upon the constitutionality of an act of the General Assembly of the State of Louisiana, passed in 1890, providing for separate railway carriages for the white and colored races. Acts 1890, No. 111, p. 152. The first section of the statute enacts “that all railway companies carrying passengers in their coaches in this State shall provide equal but separate accommodations for the white and colored races by providing two or more passenger coaches for each passenger train, or by dividing the passenger coaches by a partition so as to secure separate accommodations: Provided, That this section shall not be construed to apply to street railroads. No person or persons, shall be admitted to occupy seats in coaches other than the ones assigned to them on account of the race they belong to.” The Supreme Court’s ruling in Plessy v. Ferguson was problematic because

In the Plessy v. Ferguson case, the Supreme Court’s ruling of the “separate but equal” law being constitutional was problematic because the “separate but equal” law accepted segregation and the discrimination that were against blacks.

## An oxygen bottle containing a fixed volume of o2 gas has a pressure of 800.00 mm hg and a temperature of 295k. if the bottle is heated to 328k what will the pressure of o2 gas be within the bottle and which law will you use to solve it?

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.

Industrialization led to rising imperialism because
1) show of power: As one makes new technology, they would either want to test it out or show the other nations that what they produce is ground-breaking and the best. Usually if it is military technology, you would want to test it out, and with the use of “show of force”, can have people groups submit to your country.
2) Better technology: As technology advances, it usually makes something easier. In the case of imperialism, better military advances meant that they could (once again) have other people submit to you
3) Better transportation: This meant that you could take multiple countries at once, and can prove that you’re country is great by having supplies shipped over long distances to keep your troops up. If in need of more troops, you could send more.

Option C – BD=76 cm

Step-by-step explanation:

Given : You are designing a diamond-shaped kite. you know that AD = 44.8 cm, DC = 72 cm, and AC = 84.8 cm.

To find : How long BD should it be?

Solution :

First we draw a rough diagram.

The given sides were AD = 44.8 cm, DC = 72 cm and AC = 84.8 cm.

According to properties of kite

Two disjoint pairs of consecutive sides are congruent.

DC=BC=72 cm

The diagonals are perpendicular.

So, AC ⊥ BD

Let O be the point where diagonal intersect let let the partition be x and y.

AC= AO+OC

AC=   …….[1]

Perpendicular bisect the diagonal BD into equal parts let it be z.

BD=BO+OD

BD=z+z

Applying Pythagorean theorem in ΔAOD

where H=AD=44.8 ,P= AO=x , B=OD=z

………[2]

Applying Pythagorean theorem in ΔCOD

where H=DC=72 ,P= OC=y , B=OD=z

…………[3]

Subtract [2] and [3]

……….[4]

Add equation [1] and [4], to get values of x and y

Substitute x in [1]

Substitute value of x in equation [2], to get z

We know, BD=z+z

BD= 38.06+38.06

BD= 76.12

Nearest to whole number BD=76 cm

Therefore, Option c – BD=76 cm is correct.

B.States passed laws to work around Constitutional law. C.Some state officials moved African-Americans to other states. D.Some states ignored the Constitution

After the US Civil War,  the federal goverment aimed to guarantee equality of rights for all US citizens, by including such provision in the  US Constitution. This happened during the so-called Reconstruction era, through the enactment of the 13th, 14th and 15th Amendments in 1865, 1868 and 1870 respectively. These amendments abolished slavery and included the Equal Protection clause, that guaranteed equality of rights for all US citizens without discrimination in terms of race, color or previous condition of servitude.

Many Southern states disagreed with the Equal Protection clause and started to issue laws which aimed to circumvent it. These are called Jim Crow laws.

For example, for preventing black citizens from voting, newly-enacted laws set voting requirements, such as a minimum income level or a literacy test. In the end, the result of such laws, was that most black citizens could not exercise their right to vote.

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.

## Which of these descriptions best defines a scientific law?

A scientific law describes what occurs every time in a situation. A scientific law is a statement based that is developed from repeated experiments that describe any occurrence in the Universe that will apply anywhere under the same conditions. The term “scientific law” is traditionally associated with the natural sciences, though the social sciences also contain laws. An example of a scientific law in social sciences is Zipf’s law. Newton’s theory of gravitation, theory of gravitation, theory of gravity. law of gravitation, Newton’s law of gravitation – (physics) the law that states any two bodies attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

The first of the three most basic scientific laws is the First Law of Thermodynamics. This law states that neither matter nor energy may be created or destroyed, but they may change forms. This law of science suggests that matter must be eternal.

## When jogging outside you accidentaly bumb into a curb. Your feet stop but your body continues to movr foward and you end up on the ground. Which law of motion is being described in this scenario?A.Law of universal gravitationB.Newton’s first law of motionC.Law of conservation of energyD. Newton’s second law of Motion

Velocity of plane = 30.93 m/s

Explanation:

Considering vertical motion of ball

Initial velocity, u =  0 m/s

Acceleration , a = 9.81 m/s²

Displacement, s = 195 m

We have equation of motion s= ut + 0.5 at²

Substituting

s= ut + 0.5 at²

195 = 0 x t + 0.5 x 9.81 x t²

t = 6.31 seconds

Now considering horizontal motion of ball

Acceleration , a = 0 m/s²

Displacement, s = 195 m

Time, t = 6.31 s

We have equation of motion s= ut + 0.5 at²

Substituting

s= ut + 0.5 at²

195 = u x 6.31 + 0.5 x 0 x 6.31²

u = 30.93 m/s

Velocity of plane is horizontal initial speed of ball = 30.93 m/s

Velocity of plane = 30.93 m/s
