identify two types of systems of government from the following description: columbia is located on the northern tip south america its government is centered in its largest city bogota which has the final say on all laws which are handed down to its thirty-two departments (states) the executive of columbia is chosen by a popular vote once every four years
Answers
Answer:
The Government of Colombia is a republic with separation of powers into executive, judicial and legislative branches. Its legislature has a congress, its judiciary has a supreme court, and its executive branch has a president. The Republic of Colombia is a unitary republic comprising 32 departments, and one capital district. Since Colombia adopts the representative, republican, and democratic form of government, it is governed by representatives of the people, who are elected through direct vote. As a Civil Law country, Colombia’s legal system is mainly based on codes and laws rather than jurisprudence. One of the main characteristics of civil law countries is that their legal system does not recognize the jurisprudence as part of their legal bodies, which means that court’s decisions are only binding for the parties involved rather than for everyone. Judicial decisions are applied case by case and serve as a reference for other judges. However, in Colombia, as well as in some other civil law countries, the high courts’ decisions have gained more power and their scope is not limited as it was previously. In certain occasions, especially in high profile cases where the matters are controversial, a court’s interpretation of the law is just as important as the written law itself. The Colombian National Constitution of 1991 states in Article 1 that “Colombia is a social state of law, organized in the form of a unitary, decentralized republic, with autonomy of its territorial entities, democratic, participatory and pluralist." This means that the central government has the power to make the most important political decisions. Colombia only has a legislative authority, which is responsible for making the laws for the entire territory. The country is divided in territorial entities called departments (equivalent to states in the U.S.) that are separated into districts and local municipalities. These entities do not have legislative or judicial authority. However, as the executive branch of Colombia is administratively decentralized, there are representatives in the departmental, district, and municipal department levels. The representatives in these three levels have certain limited powers that are independent from the central authority.

gravity is 9.8 m/s^2, what is the meteor's potential energy if it has a mass of 10
kg at an altitude of 400 m?
O A. 408 J
O B. 7,840,000 J
O C. 2J
O D. 39,200 J
Answers
Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J
correct option will be a) 39200 J

What idea about work and force does the diagram describe? Explain your answer.
Answers
Answer:
W = F*d, where displacement is always in the same direction as the force. The work done by a constant force is proportional to the force applied times the displacement of the object.
Explanation:
F and W are directly proportional to each other, while F and d are indirectly propotional.
Idea about work and force in the diagram describes below.
What is work?The product of a force's component acting in the displacement's direction and its magnitude is known as the work done by the force. The following formula can be used to compute work: multiply force times distance in the direction of force.
W = F × d
The Joule is the SI unit of work .
According to the figure, In two cases force is applied to an object to reach it to same height. As potential energy at a height due to gravitation remains same. So, total work done in both cases is same after applying different forces and covering different distance.

Describe 3 factors an engineer should take into consideration when choosing material for building the pipes in a pipeline
Gr. 8
Think it has something to do with Viscosity, Density, and Pressure but not sure what
Answers
Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)
Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.
2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.
3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.
The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.
