Mountains can be formed in different ways from one another.

Answer:

the reaction force in this situation would be B

Explanation:

The action is the wings pushing down whilst the reaction is the air pushing up which allow the bird to fly .

plz mark brainliest to help me lvl up :P

Explanation to help get you the answer, not straight-up though:

Both fixed and flapping wings work by deflecting air downwards, says Professor Geoffrey Spedding, Chairman of Aerospace and Mechanical Engineering at the University of Southern California. " [When air is forced downwards] the reaction force is upwards, and this lift force supports the bird's weight. The bird’s wing pushes against the air and the air pushes back with an equal and opposite force. Unfortunately, with every down stroke there must be an up stroke, what goes up must come down. If the bird had an equal upward stroke to its downward stroke, the net force of the bird’s wing flaps would equal zero.

People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.

Answer: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows: Heart, Blood Vessels, Arteries, Veins, and Capillaries.

Explanation: The human circulatory system can be arranged from the highest to the lowest degree of internal organization as follows:

Heart: The heart is a vital organ responsible for pumping oxygenated blood to the body and deoxygenated blood to the lungs. It consists of chambers (atria and ventricles) and valves that regulate blood flow.

Blood Vessels: Blood vessels form a network of tubes that transport blood throughout the body. They can be classified into three types: arteries, veins, and capillaries.

Arteries: Arteries are thick-walled blood vessels that carry oxygenated blood away from the heart to various parts of the body.

Veins: Veins are blood vessels that transport deoxygenated blood from the body back to the heart. They have thinner walls compared to arteries and contain valves to prevent backflow.

Capillaries: Capillaries are tiny, thin-walled blood vessels that connect arteries and veins. They facilitate the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.

Please note that this arrangement is based on the internal organization of the circulatory system, with consideration given to the hierarchical structure and function of each component.

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.

Explanation:

Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

Answer:

The Holographic Principle, proposed by physicist Gerard 't Hooft and further developed by Juan Maldacena, is a fascinating concept in theoretical physics that has sparked significant interest and research. In the context of the AdS/CFT correspondence, it suggests that a gravitational theory in a higher-dimensional space can be mathematically equivalent to a quantum field theory in a lower-dimensional space.

At the heart of the Holographic Principle is the idea that the information and dynamics of a higher-dimensional theory can be fully captured by its boundary, implying that the entire bulk can be "holographically" encoded on the boundary. This concept challenges our conventional understanding of the relationship between space, gravity, and quantum mechanics.

The holographic duality proposed by Maldacena specifically relates a gravitational theory in Anti-de Sitter space (AdS) with a conformal field theory (CFT) in one fewer dimension. In this correspondence, the gravitational theory describes a curved space-time with gravity, while the CFT is a quantum field theory without gravity but living on the boundary of the AdS space. The holographic duality suggests that the two theories are mathematically equivalent and provide equivalent descriptions of the same physical phenomena.

The mathematical foundations of the AdS/CFT correspondence involve advanced concepts from string theory and quantum field theory. String theory postulates that fundamental particles are not point-like entities but rather tiny vibrating strings. By considering these strings propagating in a higher-dimensional space, theorists discovered that they naturally give rise to gravity. The holographic duality emerged as a surprising consequence of studying string theory in the AdS space.

The implications of the Holographic Principle are profound. First and foremost, it suggests a deep connection between gravity and quantum mechanics, two fundamental pillars of modern physics that have been notoriously difficult to reconcile. The holographic duality provides a framework to study strongly interacting quantum systems in terms of gravity, enabling insights into the nature of black holes, the behavior of matter in extreme conditions, and other phenomena that are challenging to analyze using traditional methods.

The Holographic Principle also has potential implications for our understanding of black holes. It proposes that the information that falls into a black hole is not destroyed, as suggested by the Hawking radiation phenomenon, but rather encoded on its event horizon. This idea, known as the "holographic encoding of information," has stirred intense debates and ongoing research in the field of black hole information paradox.

Furthermore, the Holographic Principle challenges our traditional notions of spacetime. It suggests that spacetime, as we perceive it, might emerge as an approximation or an emergent property from a more fundamental description involving quantum information. This notion aligns with the concept of "entanglement entropy," which measures the entanglement between quantum states and has been linked to the geometry of spacetime.

The potential revolutionary impact of the Holographic Principle lies in its potential to provide a unified framework for understanding quantum gravity and resolving long-standing mysteries in theoretical physics. It opens new avenues for studying the nature of black holes, the behavior of matter in extreme conditions, and the fundamental structure of the universe. However, it is important to note that the Holographic Principle is still an area of active research, and many aspects of its implications and applications continue to be explored and refined by physicists.

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.
