Explanation:

The upward push from the table does not cause the book to rise because it is at equillibrium with the downward gravitational force/ weight of the book which allows it to stay in place and not go up. What is the speed of a 4 kg ball with a momentum of 12 kg *m/s?

Answer 2

Assuming a student pushes a 51.5-kilogram bookshelf across a smooth floor with a net force of 67 N. The approximate acceleration of the bookshelf is:1.3 m/s².

Acceleration

Using this formula

Acceleration=Net force/Mass of bookshelf

Where:

Mass of bookshelf = 51.5 kilogram

Net force = 67 Newton

Let plug in the formula

Acceleration=67/51.5

Acceleration=1.30 m/s²

Inconclusion the approximate acceleration of the bookshelf is:1.3 m/s².

Quinton is describing the similarities and differences between the life cycle of an orange tree and a cypress tree.

Answers

The land absorbs and releases heat quickly, while water absorbs and releases heat at a slower rate.

The rates of absorption and release of heat in water compare to one another the land absorbs and releases heat quickly, while water absorbs and releases heat at a slower rate. Thus, option (b) is correct.

What is land?

Land is the term used to describe the area of the earth's surface. Humans benefit from forest, animal, soil, minerals, and plantation land types. The ecology includes the land. Without land, the living things would perish. This corner of the world is unique. The United States government is managing the poor people's cultural reservation on the land.

Land absorbs and releases heat faster, but water absorbs and emits heat slowly. Because water has a higher specific heat than dry soil, it absorbs and dissipates energy more slowly than soil. Water is a slow heat carrier when compared to air or land.

As a result, the conclusion of the land absorbs and releases heat quickly, while water absorbs and releases heat at a slower rate are the aforementioned. Therefore, option (b) is correct.

Question: How well does this article explain resources, scarcity, or goods? Use information from the article to support your answer.

Answers

Answer:

Scarcity of goods and services is an important variable for economic models because it can affect the decisions made by consumers. For some people, the scarcity of a good or service means they cannot afford it. The economy of any place is made up of these choices by individuals and companies about what they can produce and afford.

The goods and services of any country are limited, which can lead to scarcity. Countries have different resources available to produce goods and services. These resources can be workers, government and private company investment, or raw materials (like trees or coal). Certain limits of scarcity can be balanced by taking resources from one area and using them somewhere else. Sellers like private companies or governments decide how the available resources are spread out. This is done by trying to strike a balance between what consumers need or want, what the government needs, and what will be an efficient use of resources to maximize profits. Countries also import resources from other countries, and export resources from their own.

The topic I pick is FAS( fetal alcohol syndrome). The main reason I would pick this is because of how much this affects unborn fetuses/babies and mother. You are probably wondering what exactly is FAS. FAS or fetal alcohol syndrome is just as bad as it sounds. It is when a mother does various things such smoke, drink alcohol,uses drugs etc. during pregnancy. This could lead to various problems and deformations. The child could have behavioral problems and learning disabilities. But that’s not the extreme case. In extreme cases the child could have face deformities such as closed or thin eyelids, elongated or very small heads, extra toes or fingers, and missing limbs or organs. During pregnancy if the mother is drinking she could have a miscarriage because what she is ingesting the fetus is receiving through the placenta, thus the fetus wouldn’t survive because it has a weaker immune system than that of the mother. In my point I’m saying that we should completely make it illegal or ban pregnant women smoking, drinking alcohol, or doing anything that would affect the fetus in a bad way.
