To determine the most likely identity of the unknown mineral based on its scratching behavior, we need to consider the relative hardness of different minerals. Hardness is a measure of a mineral's resistance to scratching or being scratched by other substances.
Based on the information provided, we can infer that the unknown mineral is harder than copper (which is relatively soft) since it can scratch a copper coin. However, it is not harder than the pocket knife blade since it cannot scratch it.
The most commonly used scale to assess mineral hardness is the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest). Given the scenario, the most likely identity for the unknown mineral would be a mineral with a hardness between that of copper (2.5-3 on the Mohs scale) and the pocket knife blade (around 5-6 on the Mohs scale).
Considering this, a possible identity for the unknown mineral could be a mineral with a hardness around 4 on the Mohs scale, such as fluorite or orthoclase feldspar. However, without further information or conducting additional tests, it is challenging to determine the exact identity of the mineral with certainty.

Why do you think it is important to be accurate and unbiased
when coming to a conclusion in science and in life ? plz help
Answer:
here your answer
Explanation:
Two researchers published a paper on how the Internet is a big factor in announcing scientific discoveries but also can mislead the public due to bias and inaccurate reporting.
One thing that is important in reporting discoveries and disseminating information based on science is that it has to be accurate and unbiased. Science is based on experiments that should be both observable, measurable, and repeatable.
When CERN announced the discovery of the possible Higgs particle, they reported it as a 5 sigma discovery. This means that the discovery has a probability of 0.00003% that the result is accidental or due to chance.
Science reporting must be based on facts. Theories, although not yet proven to be science fact, still undergo scrutiny and has a fundamental principle behind it. The Higgs particle was a theory before, and it took the construction of the Large Hadron Collider for it to be discovered.
And even then, the discovery of the Higgs helps establish another theory which is the Standard Model.
There will be dissenting arguments when it comes to scientific research. Some are even on opposite sides such as Loop Quantum Gravity vs. String Theory. But regardless, it will ultimately fall on research being observable, measurable, and repeatable.
Personal beliefs has no room when it comes to science reporting. A recent article touched on how a Wikipedia editor kept deleting references to Global Warming on the Hurricane Sandy page because he personally does not believe in Global Warming

I do not believe that a strong nation should be able to boss around weaker nations. This is just wrong in that a nation should be free to decide what it wants to do. A strong nation can assist them in developing. How ever they should not rule them. At that point that weaker nation will be stripped by of their sovereignty. This is not that times of Empires.

Which came first, the Chicken or the Egg?
Eggs come from chickens and chickens come from eggs: that’s the basis of this ancient riddle. But eggs – which are just female sex cells – evolved more than a billion years ago, whereas chickens have been around for just 10,000 years. So the riddle is easily solved…or is it?
Taken at face value, there is no doubt that the egg came before the chicken. We tend to think of eggs as the shelled orbs laid by birds from which their chicks hatch – unless we eat them first. But all sexually reproducing species make eggs (the specialised female sex cells). That’s 99.99 per cent of all eukaryotic life – meaning organisms that have cells with a nucleus, so all animals and plants, and everything but the simplest life forms.
We don’t know for sure when sex evolved but it could have been as much as 2 billion years ago, and certainly more than 1 billion. Even the specialised sort of eggs laid by birds, with their tough outer membrane, evolved more than 300 million years ago.
As for chickens, they came into being much later. They are domesticated animals, so evolved as the result of humans purposefully selecting the least aggressive wild birds and letting them breed. This seems to have happened in several places independently, starting around 10,000 years ago.
The wild ancestor of chickens is generally agreed to be a tropical bird still living in the forests of Southeast Asia called the red junglefowl – with other junglefowl species possibly adding to the genetic mix. From these origins, humans have carried chickens around the world over the past two millennia or more.
So, eggs dramatically predate chickens. But to be fair to the spirit of the riddle, we should also consider whether a chicken’s egg predates a chicken. As humans consistently chose the tamest red junglefowls and bred them together, the genetic makeup of the resulting birds will have shifted. At some stage during this domestication process the red junglefowl (Gallus gallus) evolved into a new subspecies, Gallus gallus domesticus, AKA the chicken.
In practice, it is impossible to pinpoint the moment when this happened. But in theory, at some point two junglefowl bred and their offspring was genetically different enough from the species of its parents to be classified as a chicken. This chicken would have developed within a junglefowl egg and only produced the very first chicken’s egg on reaching maturity. Looked at this way, the chicken came first.

What is the process and material that forms a protective seal that hardens around an
organism?
What type of fossil fuel is created by several layers of carbonized plant materials
Answer:
The process and material that forms a protective seal that hardens around an organism is explained below in complete details.
Explanation:
Arthropods, invertebrates with exoskeletons, use extremely tough shell material such as cuticle as protection. cuticle layers are formed through secretion from the epidermis, continuously building up over time. therefore, wounds are meant to be absorbed by the exoskeletons and prevent damage to the softer inner tissues. the organism does not heal these wounds but continuously bolsters the protective exoskeletons through secretion.

b. Building terraces on sloping land to grow rice, which destabilizes hillsides
C. Burning extensive areas of forested land to create pasture, which decreases biodiversity
d. Burning small areas of forested land for subsistence farming, which increases biodiversity
e. Moving livestock to higher pasture areas in the spring, which leads to soil degradation
Which of the folloin
Answer:The correct answer is option "Burning extensive areas of forested land to create pasture, which decreases biodiversity".
Explanation:
The missing options of this question are:
A) Clearing small patches of land to pasture dairy cows, which decreases water pollution from runoff.
B) Building terraces on sloping land to grow rice, which destabilizes hillsides.
C) Burning extensive areas of forested land to create pasture, which decreases biodiversity.
D) Moving livestock to higher pasture areas in the spring, which leads to soil degradation.
The correct answer is option C) "Burning extensive areas of forested land to create pasture, which decreases biodiversity".
Tropical regions are rich in forested landscapes, where multiple species of animals and plants live. The agricultural practice that most significant long-term environmental impact is to burn these areas to create pasture. It is estimated that burning forested lands cannot be recovered in least than 28 years, while some areas have permanent damages.
Explanation:
The forest is a home for number of multiple species for their necessities and survival. These regions have high volume of forested landscapes. Different agricultural practices are performed in these areas.
Burning extensively the area of land covered with forest with a view to create pasture results in a decrease in biodiversity and has a significant environmental impact on tropical regions in long term.
Agriculture practices These areas are burned with a view to create of forest pastures. The practice of burning these areas has the most significant impact on environment in the long run.Practicing such agricultural practices of burning areas may result in permanent infertility of such areas. The damages caused by the burning of such areas can result in degradation of land and such land cannot be recovered for a estimated period of 28 years.Therefore OPTION C "Burning extensive areas of forested land to create pasture, which decreases biodiversity" is correct.

_____ happens when gravity moves sediment downhill.
a. Weathering only
b. Mass movement
c. Erosion only
d. Gravity
Answer:
B
Explanation:
A mass movement denotes a political party or movement which is supported by large segments of a population. Political movements that typically advocate the creation of a mass movement include the ideologies of communism, fascism, and liberalism. Both communists and fascists typically support the creation of mass movements as a means to overthrow a government and create their own government, the mass movement then being used afterwards to protect the government from being overthrown itself; whereas liberals seek mass participation in the state apparatus of representative democracy.
Answer:
B. Mass movement
Explanation:
Gravity can cause erosion and deposition. Gravity makes water and ice move. It also causes rock, soil, snow, or other material to move downhill in a process called mass movement.

Part 1 Answer the following questions. Place your responses in the essay box below for Part 1. What type of map is this? Are there any faults on the map? If so, what types? Around the Salt Lake, what is the geologic age of the area and what type of geologic unit is found there? South of Richfield, what type of rock is most prevalent? Which geologic area or rock is the oldest? Which geologic area or rock is the youngest? Are there any intrusive rocks found in Utah? And where? In the Green River and Price area, what fossil fuel would you expect to find there?
The type of map represented in the picture is a geological map. Geological maps show features such as soil and rock type and structural features such as faults. There are numerous faults represented on the map The main type observed are thrust faults. The area around Salt Lake is approximately between Quaternary to late Tertiary based on the map. The main geologic unit in this area is composed of alluvial, glacial and lake sediments. Middle Tertiary volcanic rocks can be found south of Richfield. Pre-Cambrian metamorphic (narrow outcrop east of the Great Salt Lake) and igneous rocks are the oldest represented on the map. The youngest rocks are Quaternary salt flats found mainly south-west of the Salt Lake. Intrusive rock outcrops can be found in different areas on the map. Outcrops can be observed southeast of Richfield, south-east of Ceder Clay and North of Lake Powell. Coal is the fossil fuel type present in the Green River and Price area.

How many sides does a polygon with a exterior angle of 5 have?
Answer:
72
Explanation:
A wire is 30 inches long is bent into a triangle with sides measuring g 6 inches 11 inches 13 inches find the measure of the largest angle
Answer:
Largest angle is 94.22°
Explanation:
The sides of the triangle are given as 6 inches, 11 inches, 13 inches.
Now, we can find the respective interior angles of the triangle using cosine rule.
Thus, for the angle opposite 6 inches, let's label it A. Thus;
6² = 11² + 13² - 2(11 × 13)cos A
36 = 121 + 169 - 286cosA
36 = 290 - 286cos A
290 - 36 = 286cosA
cosA = 254/286
A = cos^(-1)0.8881
A = 27.36°
Similarly;
11² = 6² + 13² - 2(6 × 13)cos B
121 = 36 + 169 - 156cosB
121 = 205 - 156cos B
205 - 121 = 156cosB
cosB = 84/156
B = cos^(-1)0.5385
B = 57.42°
Sum of angles in a triangle is 180°
Thus;
C = 180 - (27.36 + 58.42)
C = 94.22°
Thus,largest angle is 94.22°
The sum of the internal angle of the triangle is 180 degrees. Then the measure of the largest angle is 95.22°.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a triangle.
A wire is 30 inches long and is bent into a triangle with sides measuring 6 inches 11 inches 13 inches find the measure of the largest angle.
Then we know that the cosine rule is given as
[tex]\rm cos\ C = \dfrac{a^2+b^2-c^2}{2ab}[/tex]
Let the angle of the triangle be A, B, and C.
Then the first angle A will be
[tex]\begin{aligned} cos \ A &= \dfrac{6^2+11^2-13^2}{2*6*11}\\\\cos \ A&= \dfrac{36 + 121 - 169}{132}\\\\ A &= 95.22^o \end{aligned}[/tex]
And we know that the sum of the internal angle of the triangle is 180 degrees.
∠A + ∠B + ∠C = 180°
95.22° + ∠B + ∠C = 180°
∠B + ∠C = 84.78°
More about the trigonometry link is given below.
