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.

How do we know there has not been an increase in the number of earthquakes? Officials from the U.S. Geological Survey, the government agency that keeps track of earthquakes, point to statistics. On average, there have been no more earthquakes so far in 2010 than there were in previous years.
What Happens During Earthquakes?
In reality, it's not the number of quakes that has gained our attention, but the devastating impact quakes can have. Earthquakes are very natural—it's inevitable that they'll happen because of the way the planet works. The earth's surface is made up of tectonic plates that fit together like puzzle pieces and are always moving past each other. When two of the plates' edges get caught, stress builds up at the fault line—the crack between the plates. When the plates are finally able to break free of each other, the stress is released, and an earthquake occurs. Earthquakes of varying strengths happen every day, usually at fault lines. Some of these quakes have a high magnitude, while others are relatively weak. But it's often where an earthquake takes place that determines whether it will be something that goes largely unnoticed, or a disaster that affects thousands of people.
What Is Changing?
In the past, earthquakes were not as much of a problem because Earth's population was smaller, and cities were less populated.
"Look at some of the big [earthquakes] recently," said Debarati Guha-Sapir of the World Health Organization. Guha-Sapir cited some earthquakes that took place in areas where the population had increased in recent years, making the quakes more serious. "Had the Izmit or Bhuj quakes [of 1999 and 2001] happened 30 years ago, the events would have been relatively insignificant, as the [populations] of these cities were a third of what [they were when the earthquakes happened]. Increasing population density makes a small event into a big one."
Some of the earthquakes that took place in early 2010 occurred in highly populated areas, as well. More people are moving into megacities that happen to be built on fault lines—and many cities are on fault lines. Of the 130 cities with more than one million people, more than half are in earthquake zones, making them more prone to earthquakes.
In many of these cities, officials have drawn up laws requiring that buildings be designed and constructed to endure earthquakes. But some cities, particularly those in developing countries, lack the resources to do this. There, people are rapidly putting up substandard buildings that can't withstand the force of the shaking earth. For example, the Haiti earthquake took place near the nation's crowded capital. There was a great deal of destruction because there were "too many people crammed into a city that wasn't meant to have that many people and have an earthquake," said University of Miami geologist Tim Dixon.
Another reason quakes seem worse is that we're paying more attention. Everyone noticed when the Haiti earthquake was quickly followed by the Chile earthquake. Many people watched the news and the Internet for updates on these disasters, unable to believe that they were seeing two major earthquakes in such a short period of time. But eventually, the earth will have a period when earthquakes are minor or in unpopulated areas. Then people won't notice quite so much anymore.
"People are paying attention to the violent planet we've always lived in," said Dennis Mileti, a seismic researcher. "Come back [at a time when] there have been no [noticeable] earthquakes, [and] most people will have forgotten [about them] again."
According to the article, what is one reason why it seems as if the world is experiencing more earthquakes than usual?

What property of matter takes up space
Answers
Answer:
Density
Amount of matter = mass
Amount of space it takes up = volume
Explanation:
Calculate the change in the kinetic energy (KE) of the bottle when the mass is increased. Use the formula
KE = one half.mv2, where m is the mass and v is the speed (velocity). Assume that the speed of the soda bottle falling from a height of
0.8 m will be 4 m/s, and use this speed for each calculation.
Record your calculations in Table A of your Student Guide.
When the mass of the bottle is 0.125 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.250 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.375 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.500 kg, the KE is
kg m2/s2.
Answers
Answer:
The answers are the options 1, 2, 3, and 4
Explanation:
If you have any questions ask me please! :)
The kinetic Energy of the bottle falling from a height of 0.8m for different masses of (0.125,0.250,0.375,0.500)kg is (1,2,3,4) kgm*2/s*2 respectively.
Let's calculate the kinetic energy for different masses having a velocity of 4m/s in each case,
Using Formula:
K.E=\(1/2mv^{2}\)
When the mass of the bottle is 0.125 kg, the Kinetic Energy is
K.E=\(1/2(0.125)(4)^{2}\)
K.E=\(1/2(0.125)(16)\)
K.E=1/2(2)
K.E=1
When the mass of the bottle is 0.250 kg, the Kinetic Energy is
K.E=\(1/2(0.250)(4)^{2}\)
K.E=1/2(0.125)(16)
K.E=1/2(4)
K.E=2
When the mass of the bottle is 0.125 kg, the Kinetic Energy is
K.E=\(1/2(0.375)(4)^{2}\)
K.E=1/2(0.375)(16)
K.E=1/2(6)
K.E=3
When the mass of the bottle is 0.500 kg, the Kinetic Energy is
K.E=\(1/2(0.500)(4)^{2}\)
K.E=1/2(0.500)(16)
K.E=1/2(8)
K.E=4
Now we can calculate the change in kinetic energy (ΔKE):
ΔKE = KE(final) - KE(initial)
= 4 kg m*2/s*2 - 1 kg m*2/s*2
= 3 kg m*2/s*2

Explain the relationship between wavelength and frequency in the electromagnetic spectrum.
Answers
Answer:
The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength
Explanation:
The wavelength and frequency of an electromagnetic wave are inversely proportional to each other.
What is Wavelength and frequency?Wavelength is the distance between any two identical points or adjacent crests in the adjacent cycles of a waveform signal which is propagated in space or along a wire. In the wireless systems, this length is usually specified in the units of meters (m), centimeters (cm) or millimeters (mm).
Frequency is the rate at which the current changes its direction per second time. Frequency is measured in the units of hertz (Hz), an international unit of measure where, 1 hertz is equal to 1 cycle per second of time.
The wavelength in an electromagnetic spectrum is inversely proportional to the frequency of the wave. The shorter the wavelength, the higher the frequency of the wave. Because, all light waves move at the same speed in a vacuum medium, the number of wave crests passing at a given spot in one second is determined by the wavelength of the wave.

How is the Moon different during a new moon phase than during a lunar eclipse?
Answers
Answer:
A solar eclipse happens at the new moon phase, when the moon passes between the sun and Earth. A lunar eclipse happens at the opposite moon phase – at full moon – when the Earth, sun and moon align in space, with Earth between the sun and moon. EarthSky's lunar calendar shows the moon phase for every day in 2021.
Explanation:
During a new moon, it is more or less between the Earth and the Sun, whereas a lunar eclipse ALWAYS occurs during a full moon.
The new moon is the astronomical phase that indicates the beginning of a new lunar cycle.During a new moon, the moon is found between the Earth and Sun (not exactly between), thereby the moon's surface is dark because the light side is facing away from Earth.Conversely, a lunar eclipse occurs when the moon passes through the shadow of the Earth, which only happens during a full moon.In conclusion, during a new moon, it is more or less between the Earth and the Sun, whereas a lunar eclipse ALWAYS occurs during a full moon.
