Describe 3 factors an engineer should take into consideration when choosing material for building the pipes in a pipeline
Gr. 8
Think it has something to do with Viscosity, Density, and Pressure but not sure what
Answers
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.

Any atom which no longer has a neutral charge is called a blank
Answers
Answer:
atoms that no longer have a neutral charge are called ions!
Explanation:
when atoms gain or lose electrons, they become either negatively charged or positively charged in the process. losing electrons means the atom becomes more positive, therefore positively charged. gaining electrons means the atom becomes more negative, so negatively charged. atoms that go through this process of gaining or losing electrons are called ions.

A. on the equator
B. on the southern hemipshere
C. on the northen hemipshere
D. on both hemispheres
Answers
Answer:
C
Explanation:
..............................
The Northern Hemisphere is experiencing the summer season, then most of the direct sunlight located on Earth at that time would be on the northern hemisphere, therefore the correct answer is option C.
What is the equator?The Equator is an imaginary line passing through the middle of a globe. It is equidistant from the North Pole and the South Pole, Its is a horizontal line residing at 0 degrees latitude.
The seasons vary according to the relative position of the sun and the earth, for example, if there is a summer season in the northern hemisphere then most mount of the sunlight would fall on the northern hemisphere as per the relative position of the sun and the earth.
Thus, the correct answer is option C.

you are on the airplane, about to fly to an exotic location. How do acceleration, speed and inertia work to overcome the forces of gravity and air resistance during the take-off?
Answers
Answer:
Make a paper airplane and have him toss it. his arm would be the thrust, the wings would provide lift, the shape of it would minimize drag (air resistance). However, if he put an engine on the same airplane, it would do the same thing as your arm would do.
So thrust, lift, shape.... Inertia is just a by product of the force that pushing you into your seat.

According to the passage, carbon dioxide is the most abundant greenhouse gas on Earth. What is the leading cause of Carbon Dioxide rising in the last 100 years?
Answer the question using the CER strategy. Be sure to use evidence from source 1 and 2.
Answers
Answer:
Human activities, especially the burning of fossil fuels like coal, oil, and natural gas, are primarily to blame for the rise in carbon dioxide levels over the past 100 years. Carbon dioxide is produced as a byproduct of combustion when these fossil fuels are burned for transportation, industrial processes, energy production, and other uses. Together with other greenhouse gases, this human-caused release of carbon dioxide has significantly boosted atmospheric carbon dioxide concentrations, causing the greenhouse effect and amplification of global warming and climate change.

Answers
Yes, I noticed that a magnet could be used to move the paper clip without touching it.
It is similar to the floating plant because both processes involve a force acting on an object without having a direct physical contact.
The force acting on the paper clip is described as the magnetic force,
The claim can be made that magnets could move an object without physical contact by using the magnetic force to exert a force on the object.
What is magnetic force?A magnetic field is described as a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.
In this case , the magnetic force arose due to the interaction between the magnetic fields of the magnet and the paper clip.
The magnet has a magnetic field around it, which exerts a force on any nearby magnetic material, such as the paper clip.

At the time When the white dwarf with a mass of 1.4 solar masses so it is collapsed to create a neutron star. Hence, option A is correct.
What is Chandrasekhar's limit?It is the maximum mass of stabling the white dwarf star. The presently accepted value should be approx 1.4 M. Also, it should collapse via the electron degeneracy pressure and it resisted the collapse via the thermal pressure.
Also, when it should be reached the limit so it should develop a neutron star.

Answers
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

Use the data in the table to explain how you could determine the volume of the block.
Answers
To find the volume of the block, subtract the initial water volume from the final water volume, convert the change in water volume to cubic centimeters, and consider it as the volume of the block.
To find the volume of the block using the measurements provided.
1. Calculate the change in water volume:
The initial water volume is given as 62.3 mL, and the final water volume is given as 89.5 mL. To determine the change in water volume, we subtract the initial volume from the final volume: 89.5 mL - 62.3 mL = 27.2 mL. This value represents the increase in water volume caused by placing the block in the graduated cylinder.
2. Convert the change in water volume to cubic centimeters:
Since 1 mL is equivalent to 1 cubic centimeter (cc), we can directly convert the change in water volume from milliliters to cubic centimeters. In this case, the change in water volume is 27.2 mL, which is also equal to 27.2 cc.
3. Determine the volume of the block:
When the block is placed in the graduated cylinder, it displaces some amount of water, resulting in an increase in water volume. By measuring this increase in volume, we can determine the volume of the block itself. In this case, the change in water volume of 27.2 cc represents the volume of the block.
By following these steps, we can find the volume of the block based on the provided measurements.
Therefore, By deducting the initial water volume from the final water volume and converting the difference in water volume to cubic centimeters, the block's volume can be calculated. the volume of the block is 27.2 cc.
