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.

Sometimes people refer to Mars as the Red Planet. Because of the rusty iron in the earth, it is red. Mars features weather, polar ice caps, canyons, volcanoes, and seasons just like Earth. Its atmosphere, which is composed of carbon dioxide, nitrogen, and argon, is extremely thin. These define Mars' characteristics.

These are some of the characteristics of the moon, which is the only natural satellite of Earth and the nearest huge celestial body. It is a spherical rocky body that revolves around Earth in a somewhat eccentric orbit at a mean distance of around 384,000 km (238,600 miles), perhaps with a tiny metallic core. It has a 1,738 km (1,080 miles) equatorial radius.

A celestial body inside the Solar System that meets the following criteria is referred to as a "planet": (a) it must be in orbit around the Sun; (b) it must have enough mass to overcome rigid body forces and take on a hydrostatic equilibrium form that is almost circular; and (c) it must have cleared the area in and around its orbit.

Explanation:

Radiation can affect different surfaces in different ways depending on various factors. For instance, ionizing radiation can break apart water molecules in an ice-covered lake and damage plant cells in a forest, whereas non-ionizing radiation can support photosynthesis and growth. In the ocean, radiation can have both positive and negative effects, and exposure to high levels of ionizing radiation can cause damage to the asphalt of a road over time.

The effects of radiation on different surfaces can vary depending on a number of factors, including the type of radiation, the intensity of the radiation, and the properties of the surface material.

When radiation interacts with matter, it can cause a range of effects, including ionization, excitation, and heating. These effects can lead to changes in the physical and chemical properties of the material.

For example, when ionizing radiation (such as gamma rays or X-rays) interacts with water molecules in an ice-covered lake, it can break apart the water molecules and produce highly reactive free radicals. These free radicals can then go on to react with other molecules in the water, leading to changes in the chemical composition of the ice. The effects of radiation on a forest would depend on the type of radiation and the type of trees and plants present. High levels of ionizing radiation can damage or kill plant cells, leading to a reduction in growth and productivity. Non-ionizing radiation (such as visible light) can be used by plants for photosynthesis and growth.

In the case of an ocean, radiation can have a range of effects depending on the depth of the water and the type of radiation. For example, visible light can penetrate several hundred meters into the ocean, allowing photosynthetic organisms such as phytoplankton to thrive. On the other hand, ionizing radiation from radioactive materials can accumulate in the bodies of marine organisms, potentially leading to long-term health effects.

On the other hand, the effects of radiation on an asphalt road would depend on the type of radiation and the composition of the road. For example, exposure to high levels of ionizing radiation can lead to the breakdown of the chemical bonds in asphalt, potentially causing the road to become brittle and crack over time. Additionally, radiation exposure can lead to the formation of free radicals in the asphalt, which can react with oxygen in the air and cause the road surface to become discolored or faded.

Therefore, the effects of radiation on different surfaces can vary depending on a range of factors, including the type of radiation, the intensity of the radiation, and the properties of the surface material.

ANSWER:

Charge flows together through the external circuit at a rate that is everywhere the same. The current is no greater at one location as it is at another location. The actual amount of current varies inversely with the amount of overall resistance. There is a clear relationship between the resistance of the individual resistors and the overall resistance of the collection of resistors. As far as the battery that is pumping the charge is concerned, the presence of two 6-Ω ;resistors in series would be equivalent to having one 12-Ω resistor in the circuit. The presence of three 6-Ω resistors in series would be equivalent to having one 18-Ω resistor in the circuit. And the presence of four 6-Ω resistors in series would be equivalent to having one 24-Ω resistor in the circuit.

Two ways erosion affects California land are rising sea levels and soil erosion. Rising Sea Levels can cause homes to go under water and soil erosion can cause the ground to not be harvestable.

Explanation:

Erosions can have a huge effect on many things consisting in California.

Answer:

Water pollution and increased runoff

Explanation:

Erosion can cause soil infected with fertilisers, pesticides, ets. can travel to water bodies, causing that water to be polluted.

Erosion can send particles to block pores in the ground, "patching up" the ground, letting water stay on the ground instead of seeping underground, eventually leading to runoff.

Answer:

Explanation:

1.  scientists are so concerned about carbon dioxide because the more carbon dioxide in the atmosphere, the hotter the earth will become, changing the Earth's climate.

2.  389.9 parts per million

3.  Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere.

4. Any system within the Earth system is considered an open system. Because energy flows freely into and out of systems, all systems respond to inputs and, as a result, have outputs. DNA and RNA are the two things which everything on earth shares.

5. Humans play a major role in the carbon cycle through activities such as the burning of fossil fuels or land development. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising; it is already considerably greater than at any time in the last 800,000 years. One of the most important sources of energy is the sun.

6. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. ... Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.

7. Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.

8. Under elevated CO2 most plant species show higher rates of photosynthesis, increased growth, decreased water use and lowered tissue concentrations of nitrogen and protein. Rising CO2 over the next century is likely to affect both agricultural production and food quality.

Explanation:

One component of my school's recycling system that could be automated is the sorting of recyclables. Currently, the school relies on students and staff to sort recyclables into the appropriate bins, which can be time-consuming and may result in contamination if materials are not sorted properly.

Automating the sorting process with a machine or conveyor belt system could improve the efficiency and accuracy of the recycling system. It could also potentially reduce labor costs associated with manual sorting.

The economic impact of automating the sorting process would depend on the initial cost of the equipment and any associated installation or maintenance costs. However, over time, the improved efficiency and accuracy of the system could result in cost savings for the school. Additionally, the increased efficiency of the system could potentially lead to increased recycling rates, which could result in cost savings for waste disposal and potentially generate revenue through the sale of recycled materials.
