The process of generation of force by the high speed that pushes the jet engine forward is based on Newton’s _____ law of motion

jasenka [17]

Answer:

The process of generation of force by the high speed that pushes the jet engine forward is based on Newton’s 2 law of motion ?

Explanation:

1, Newton’s first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia.

2,

Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. The momentum of a body is equal to the product of its mass and its velocity. Momentum, like velocity, is a vector quantity, having both magnitude and direction. A force applied to a body can change the magnitude of the momentum, or its direction, or both.For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and a (acceleration)

3, Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.The third law is also known as the law of action and reaction. This law is important in analyzing problems of static equilibrium, where all forces are balanced, but it also applies to bodies in uniform or accelerated motion. The forces it describes are real ones, not mere bookkeeping devices. For example, a book resting on a table applies a downward force equal to its weight on the table. According to the third law, the table applies an equal and opposite force to the book.

While driving down the highway, your car must overcome the forces of friction and air resistance in order to keep the car moving

ElenaW [278]

Answer:

Efficiency of the engine equals 20%

Explanation:

We know that when the car moves it must do work against the resisting forces to keep moving and this work is spend as energy by the engine to keep the car moving.

we know that

$Work=Force\times Displacement$

Thus to keep the car moving for 100,000 meters the theoretical work that requires to be done equals

$Work=560N\times 100,000m=56\times 10^{6}Joules$

Now the actual energy spend by the car equals the energy spend by burning 2.8 gallons of gasoline.

Thus the energy produced by burning 2.8 gallons of gasoline equals

$2.8\times 100\times 10^{6}=280\times 10^{6}Joules$

Thus the efficiency is calculated as

$\eta =\frac{56\times 10^{6}}{280\times 10^{6}}\times 100\\\\\therefore \eta =20percent$

A layer of viscous fluid of constant thickness (no velocity perpenducilar to plate) flows steadily down an infinite, inclined pl

mixer [17]

Answer:

q = (ρg/μ)(sin θ)(h³/3)

Explanation:

I've attached an image of a figure showing the coordinate system.

In this system: the velocity components v and w are equal to zero.

From continuity equation, we know that δu/δx = 0

Now,from the x-component of the navier stokes equation, we have;

-δp/δx + ρg(sin θ) + μ(δ²u/δy²) = 0 - - - - - (eq1)

Due to the fact that we have a free surface, it means we will not have a pressure gradient in the x-component and so δp/δx = 0

Then our eq 1 is now;

ρg(sin θ) + μ(δ²u/δy²) = 0

μ(δ²u/δy²) = -ρg(sin θ)

Divide both sides by μ to get;

(δ²u/δy²) = -(ρg/μ)(sin θ)

Integrating both sides gives;

δu/δy = -(ρg/μ)(sin θ)y + b1 - - - - (eq2)

Now, the shear stress is given by the formula;

τ_yx = μ[δu/δy + δv/δx]

From the diagram, at the free surface,τ_yx = 0 and y = h

This means that δu/δy = 0

Thus, putting 0 for δu/δy in eq 2, we have;

0 = -(ρg/μ)(sin θ)h + b1

b1 = h(ρg/μ)(sin θ)

So, eq 2 is now;

δu/δy = -(ρg/μ)(sin θ)y + h(ρg/μ)(sin θ)

Integrating both sides gives;

u = -[(y²/2) × (ρg/μ)(sin θ)] + h(ρg/μ)(sin θ)y + b2 - - - eq3

Because u = 0 when y = 0, it means that b2 = 0 also because when we plug 0 for u and y into eq3, we will get b2 = 0.

Thus, we now have:

u = -[(y²/2) × (ρg/μ)(sin θ)] + h(ρg/μ)(sin θ)y

Factorizing like terms, we have;

u = (ρg/μ)(sin θ)[hy - y²/2] - - - (eq 4)

The flow rate per unit width is gotten by Integrating eq 4 between the boundaries of h and 0 to give;

∫u = (h,0)∫(ρg/μ)(sin θ)[hy - y²/2]

q = (ρg/μ)(sin θ)[hy²/2 - y³/6] between h and 0

q = (ρg/μ)(sin θ)[h³/2 - h³/6]

q = (ρg/μ)(sin θ)(h³/3)

HELP ASAP PLEASE!!! this is for peer counsiling

Fofino [41]

Explanation:

We can do another country like Spain and Mexico

Take what you need ok?

The Spanish language extends far beyond Spain and Mexico. One of the top five languages spoken worldwide, there are twenty official Spanish-speaking countries. Within each country or region, however, there are different dialects and varieties, making Spanish one of the most diverse languages in the world. With this great diversity comes a valid business question: Is there a “universal” or “proper” Spanish that I can use for my global business?

Linguistically speaking, the short answer: no. There is no such thing as a “better” Spanish since every dialect is unique and correct in its uniqueness. However, from a marketing point of view, the question now becomes: Is it really necessary to translate and localize for every single Spanish dialect?

Again, the answer is (generally) no. But it all depends on your target Spanish-speaking markets. If you want to reach customers in places like Peru, Argentina, or Puerto Rico, you’ll likely need to translate your content with these variations in mind.

The key is to find variations in vocabulary and grammar where Spanish is spoken and think about how they might influence your particular content. One obvious difference between Spanish in Spain and in Latin America is with the pronouns for “you.” In Latin American Spanish you don’t use the informal pronouns Tú (singular) and Vosotros (plural) as you would in Spain. Instead, the pronouns Usted and Ustedes are used for all situations. In Spain, these pronouns are only used to address somebody formally.

Of course, many people think that there are only distinctions between European Spanish and Latin American Spanish. But because every Spanish-speaking country has developed differently, this simply isn’t true. You have to take into consideration each country’s individual culture, politics, technology, and economy. These factors have great impact on the language and can make the same words mean something quite different when crossing a border.

The Influence of History

For example, some countries in South America, like Argentina or Chile, might see themselves as more European than Latin since they have primarily Spanish and Italian ancestry. The Spanish there reflects this difference: the word bunga (pickpocket) used in Chile and Argentina originated from the Italian word pungia (pocket). Argentina’s word for gun, bufoso, also originated from the Italian word buffare. But then there are some local dialects inside Peru where many Japanese and Chinese words have been Hispanicized, such as: ocha (a hot infusion), matchi (a match), and Chifa (the Peruvian name for Chinese restaurants that comes from the Chinese term 饎飯, “chi faan”, meaning “to eat rice.”) These words reflect the influence of Asia on the local culture there.

You also need to be careful when using political, ideological, and legal terminology because not all Spanish-speaking countries are ruled by the same type of government. Spain, for instance, has a constitutional monarchy while Cuba is communist. Differences in power structures make for differences in terms in Spanish, some of which don’t even have a rough equivalent in another Spanish-speaking country.

What’s in a Name?

You also need to consider that products can have completely different names depending on the country. Just think of ‘truck” and “lorry” with British and American English. Take the word “computer.” In Spain “computer” translates to ordenador, but in most Latin American countries the word is computadora.

Thinking about spreading your business through multiple Spanish-speaking countries? Be sure to go beyond translation and localize the content. Localization along with translation allows you to address the right audience from the beginning. Customers buying a coche in Spain want to come home with a car, but in Mexico, they’re in the market for baby strollers, not a family vehicle. Catching these differences before launching a campaign will save you and your Spanish-speaking customer’s confusion, no matter where your company ends up.
