Answers

Answer 1

Answer and Explanation:

First, observe and understand what is happening.

1. A balloon is on an empty glass bottle, which is placed in water that is being heated.

2. The balloon starts to become inflated, or filled with air.

5. The balloon gets inflated because:

(B) The air inside the bottle gets heated and expands.

The bottle is already filled with air (due to it being exposed before putting the balloon on it to cover the bottle). When air is heated, the molecules start to move around rapidly, coming into contact very frequently and wildly, which makes the air expand into the balloon, ultimately inflating it.

6. What do you expect if the bottle is taken out?

(A) The balloon will get deflated.

Due to the air in the bottle no longer being heated, the molecules will start to slow down, and the balloon will deflate.

7. The changes taking place in the balloon when the bottle is placed in the hot water and taken out of it are:

(A) Reversible

Although heat is used in the process, the air itself isn't changed chemically, only physically. The air can go from being at normal temperature to hot to being hot and back to normal temperature. Even if you were to freeze the air/make the air cold, the air can change back to normal temperature when heating the air.

1. When you put some glucose in your mouth, your tongue feels cold, because the dissolving of glucose in saliva is an endothermic change.

Endothermic reactions are where the reactants absorb the heat from the surrounding area to form the product. The glucose absorbs the warmth from your tongue, and as a result you feel the coldness of the glucose.

how do christians help the poor? please answer with 5 ways and explain your reasoning. urgent!

Answers

Answer:

Caring for the poor isn’t easy—but it also doesn’t need to be overwhelming, at least when we recognize poverty from a biblical point of view. I explained in an earlier article that when we begin to see poverty the way the Bible does, we begin to see it as offering a number of practical opportunities to worship Jesus.

But how we will worship—how our concern will be expressed—will differ from one person to another. The expression of our concern neither reflects nor establishes our holiness before God. Our responsibility is only to serve in the way in which we feel compelled. With that in mind, here are five things you can do to help the poor that really do help:

1. Begin in the church and move from there.So, practically, this means a couple of things: service starts within our local congregations. “If a brother or sister is poorly clothed and lacking in daily food, and one of you says to them, ‘Go in peace, be warmed and filled,’ without giving them the things needed for the body, what good is that?” James wrote (James 2:15-16). If we a need is known in the church, we are actually obligated to meet it. Remember, the early church, motivated by their love of Christ and the grace God had shown them, lived an open-handed lifestyle, sharing all they had with one another (Acts 2:44-45).

I remember a number of years ago, my family was in pretty dire straits. We were drowning, financially, not because we had a lot of debt; we simply had very little income and too many expenses. One day, after church, one of the elders of our church came up to me and quietly handed me an envelope with more than enough money to help us meet a few significant needs that month. That’s the kind of thing I’m talking about—it’s not showy acts; it’s recognizing needs and meeting them.

2. Look for simple, practical ways to serve. Consider the options around you. Perhaps it’s volunteering with an after-school program in your community, a soup kitchen or clothing pantry (and if there isn’t one in your community, perhaps you could start one through your church). Maybe it’s just as simple as buying a coffee for the man on the street who is asking for change. There are more needs around you than you might realize. Ask God to give you eyes to see and a heart to serve.

3. Work with experts you can trust. There are many different organizations working to alleviate the suffering of the poor, both locally and globally. But not all organizations are created equal. Do your homework—read whatever information an organization has made available to you and review its finances to ensure the money entrusted to it is being stewarded well. CharityNavigator.orgis a helpful resource for identifying trustworthy organizations.

4. Remember that spiritual problems require spiritual solutions. Because poverty is fundamentally a spiritual issue, we would be wise to work with organizations that recognize this truth. Look for organizations that are committed to the local church and are faithfully proclaiming the gospel, even as they minister to the physical and relational needs of the poor. One the best I know of serving the global poor in this way is Compassion International.

5. Pray and trust God for the results. Our responsibility is not to end poverty, but to minister to those who are suffering while we are here. The day is coming that Jesus will return; and on that day, He will wipe every tear from every eye. Sin, sadness, death… all of these will be gone. Poverty will be no more (Revelation 21:4). Therefore, do what you can, pray, and trust God for the results.

El servicio de correo postal entrega un paquete cuyas dimensiones son 6 por 6 por 11 pulgadas. En una nota indica que en el interior contiene una pirámide cuadrada en cristal con la misma base y altura de la caja. ¿Cuál es el volumen de la pirámide?

Answers

La opción correcta es B, 132 pulgadas cúbicas.

Dado que el servicio de correo postal entrega un paquete cuyas dimensiones son 6 por 6 por 11 pulgadas, y en una nota indica que en el interior contiene una pirámide cuadrada en cristal con la misma base y altura de la caja, para determinar cuál es el volumen de la pirámide se debe realizar el siguiente cálculo:

-sabiendo que el volumen de una pirámide surge de multiplicar la altura de la misma por un tercio del área de su base, se debe operar de la siguiente manera:

(1/3 x (6 x 6)) x 11 = X(1/3 x 36) x 11 = X12 x 11 = X132 = X

Por lo tanto, el volumen de la pirámide es de 132 pulgadas cúbicas.

The Fall of the Roman Empire

Using the web resources, in a short essay, discuss four factors which brought about the decline and fall of the Roman Empire. Your essay must include an introductory paragraph, a paragraph on each factor developing its contribution to the decline, and a concluding paragraph that ties the entire essay together. Save a copy on your computer, and then submit your document to your instructor.

Answers

Answer:

The fall of the empire did fall. The fall of the Roman Empire was caused when there was less loyalty to Rome. The Urban Centers start to collapse. Also the military, political, and Social of Rome was causing Rome to collapse. Another reason of why the Roman Rome collapsed is when the aqueducts were destroyed and some of the public works. Rome is like if one thing falls apart the whole thing falls apart. The aqueduct made Rome collapse because the people of Rome needed water in and out so, when it collapse the population just literally dropped from like a million to a couple of hundred of the people and then the people of Rome just scattered to different areas to have a better life or to move where there is water or good harvests. The metaphor I think of it of Rome falling apart is when there is a grand sand castle, mighty, powerful, and wealthy. But, then the tides get high and wash it away. This is a reference to Rome because Rome was amazing with public works like coliseums, and the beauty, of Rome was demolished, gone, population drops because the ego, the life, the wealth is gone, and that is what I think of it.
