Answer:
A. He encouraged American war fever to advance his political career.
Explanation:
The motion of an aircraft through the air can be explained and described by physical principals discovered over 300 years ago by Sir Isaac Newton. Newton worked in many areas of mathematics and physics. He developed the theories of gravitation in 1666, when he was only 23 years old. Some twenty years later, in 1686, he presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis." The laws are shown above, and the application of these laws to aerodynamics are given on separate slides.
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The key point here is that if there is no net force acting on an object (if all the external forces cancel each other out) then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. If an external force is applied, the velocity will change because of the force.
The second law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum (mass times velocity) per change in time. Newton also developed the calculus of mathematics, and the "changes" expressed in the second law are most accurately defined in differential forms. (Calculus can also be used to determine the velocity and location variations experienced by an object subjected to an external force.) For an object with a constant mass m, the second law states that the force F is the product of an object's mass and its acceleration a:
F = m * a
For an external applied force, the change in velocity depends on the mass of the object. A force will cause a change in velocity; and likewise, a change in velocity will generate a force. The equation works both ways.
1. The four states of United States that border Mexico are Texas, New Mexico, Arizona, and California. There are multiple similarities between these four states, be it in their geography or culture. The most striking similarities are that all of these four states have a very percentage of population that has Mexican ancestry, and that the Spanish language is commonly used, but at home and officially. There are two main reasons for this. One of them is that these states were once part of Mexico, so when the United States managed to conquer them, they encountered mostly Mexicans, which did not returned to Mexico but stayed in the United States. Another reason is that they border with Mexico, so the Mexicans that migrate toward the United States mostly end up in these states, or are there for at least some time.
2. The differences between these four states can be mostly seen in their economies and their cultures. The economies of these four states are all different. Texas for example is focused on the oil reserves, as well as large scale farming and ranching, while California is mostly focused on the tertiary sectors, such as its famous movie industry. The culture too differs in all of these states, which is actually a trait of any state in the United States as all of them have something specific about them. The Texans tend to be more rough, love weapons, and are much more conservative. The Californians tend to be much more libertarian, more easy going, and love the spotlight. The New Mexicans and Arizonians are not very open, they tend to be more closed and function in their communities, while not being very willing to engage with ''outsiders''.
A stalemate is a period during war where the opposing forces cannot progress (this is in terms of both a 'hot' or a 'cold' war). For example, during WW1 there was a stalemate on the Western Front due to advanced defenses built by the Allies and the Central Powers. This meant that new offensive tactics and strategies had to be employed in order for either side to gain terrain. The trench warfare system that brought about the stalemate of WW1 was triggered by the failure of Germany's Schlieffen Plan.
