Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)

Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.

2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.

3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.

The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.

Answer:

D

Explanation:

The correct answer would be in the axle of the wheels while you ride your bicycle.

Options A, B, and C requires that the forces of friction is increased in order to have more control.

However, option D requires that there is a minimal frictional force in the axle of the wheels of a bicycle while riding so that a little effort would be required to keep the bicycle moving.

The lesser the friction, the lower the effort that would be needed to keep the bicycle moving and vice versa.

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.

Answer:

One household appliance that works on the basis of electric current is a washing machine. It works by first drawing in water from the water supply, and then pumping it into the drum where the clothes are added. The washing machine then agitates the clothes with a rotating inner drum, which is powered by an electric motor. The motor is powered by electric current, which is supplied by the electrical outlet. As the drum rotates, the electric current causes the motor to turn, which in turn agitates the clothes. The effects of the electric current are seen in the form of heat generated by the motor, and a buzzing noise during operation.

Explanation: COMPOST BIN

WHAT IS A COMPOST BIN?

A compost bin is a container into which you place organic waste to turn into compost (organic material) over time.

Most compost bins are designed to hasten the decomposition of organic matter through proper aeration and moisture retention. With the proper combination of air and moisture, ideal conditions are produced for the activity of aerobic organisms responsible for the high temperatures that transform the organic materials into compost

Read on to find out how to start a compost bin, DIY compost bin ideas, and more tips for beginners.

The decomposition process will eventually take place over time in a compost "pile" or "heap," even without any housing to contain the matter. However, a compost bin is worth it because it helps speed up decomposition and keeps the area neat. Some bins are continuous, meaning you can keep adding waste to them, while others create batches of compost with a set mix of ingredients you add all at once. Depending on the style of compost bin you choose, bins can also have the advantage of making it harder for rats to get at your compost. This is true of the tumbler type, for example.

CHOOSING THE RIGHT BIN

Select the right bin for your composting needs. You can make an inexpensive compost container out of almost any container or material. Some ideas include:

Plastic storage container

Plastic bucket

Trash cans

Straw bales

Lumber

Branches harvested from the woods

Stone

Cinder blocks

Wire fencing

Ceramic (also popular for a kitchen countertop compost bin)

The best bin, however, is one you can easily turn or rotate consistently to control odors and make sure all the materials decompose. This is especially important for aerobic composting (more information below). A tumbler composting bin is pricey, but you can DIY one from barrels and sawhorses. You can turn compost with a rake or shovel in a non-rotating bin, it just takes more labor to do so.

The example of matter in the three states is brick in solid state, water in liquid state and oxygen gas in gaseous state.

1. Solid: A brick is a solid object that maintains a fixed shape and volume.

2. Liquid: A glass of water is a liquid that conforms to the shape of its container but maintains a definite volume.

3. Gas: Oxygen gas in the atmosphere is a gas that does not have a fixed shape or volume, filling the available space.

The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, such as an ice cube. Liquids have a definite volume but take the shape of their container, like water. Gases have neither a fixed shape nor volume and fill the entire space available to them, such as the air we breathe.

In summary, the states of matter describe the physical properties of substances based on the arrangement and movement of their particles, with solids having a fixed shape, liquids taking the shape of their container, and gases being free-flowing and filling all available space.

Solid: An object that keeps a constant shape and volume is a brick.

Thus, Liquid: A glass of water is a liquid that keeps a consistent volume while taking on the shape of its container. Gas: Oxygen gas fills the available space in the atmosphere and does not have a defined shape or volume.

Gas, liquid, and solid matter can exist in any combination. Solids, like an ice cube, have a set shape and volume.

Like water, liquids have a set capacity but adopt the shape of their container. Gases, like the air we breathe, have neither a set shape nor volume and fill all available space.

Thus, Solid: An object that keeps a constant shape and volume is a brick.

Explanation:

There are two factors that affect gravity: mass and distance.

Law of Gravity: Every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Gravity: the force by which each object draws all the other objects towards its center.

Gravity is affected by mass and distance.

Everything with mass has gravity.

The more mass an object has, the more gravity it has.

The farther you are from the source of gravity, the lesser of gravity you will feel.

In space, your weight will read 0 and the objects in space are hard to move due to the different gravitational forces acting upon each object from different areas.

Weight: Weight is the force of gravity on an object.

Weight is completely dependent on gravitational force acting on an object.

The more gravity there is, the more weight an object will have.

Mass and weight are not the same.

Mass does not change because it is the amount of matter in an object which does not change no matter where the object is. However, weight changes because it is the effect of gravity on an object.

In order to find weight, use the formula W=mg where W is the weight, m is the mass and g is the gravitational force.

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

So if its regular, you would always tighten it. Here's the reasoning:

"When you lower the pitch by releasing tension, there might be slack in the gears in the tuning machines, which might make the string go below the intended pitch. By going further down and approaching the target note from below, there will be force applied to the gears and when you've reached the correct pitch the gears have less potential to move. So your teacher is correct."
