Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter, causing the metal to stiffen and fracture. This is known as metal fatige. The bending causes that to occur.
What is metal ?A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Generally speaking, metals are malleable and ductile.
These characteristics are the outcome of the metallic link that exists between the metal's atoms or molecules.
The earth's crust is where most pure metals are found. They are discovered in ores, which are solid materials from which metals and minerals may be extracted. The majority of the planet's iron mass, which makes up over a third of its mass, is located in its core.
Thus, Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter.

002 (part 1 of 2) 10.0 points For :393 g of butadiene (C,11,) calculate the number of moles. Answer in units of mol.
Answer:
7.27 mol C4H6
Explanation:
To calculate moles, divide the molar mass by the grams given
To find molar mass, add the atomic mass of the elements
12.011*4 + 1.008*6 = 54.092 g/mol
393 g * 1 mol/54.092 g = 7.265 mol
How is the earth's crust different from the mantle?
A : The crust is deeper below Earth’s surface than the mantle
B : the crust is less dense than the mantle
C : the crust contains softer rock than the mantle

( this is science by the way )
Answer:
the answer is B
Explanation:
please tell if correct or not and can you give brainliest
Answer:
well i would say D
Explanation:
the crust in fact does have more iron within in it but if i describe it more i would say the crust is a smaller amount then the mantle, and that its a bit harder material then the mantle itself

Which of the following is an example of mutualism?
Answer:The relationship which is between bacteria and ungulates with the intestine is or good example of mutualism. Mutualism plays an important role in ecology. We can say that if we measure the exact fitness what we get as a benefit is a mutualistic relationship.example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra. Oxpeckers land on rhinos or zebras and eat ticks and other parasites that live on their skin. The oxpeckers get food and the beasts get pest control.

When developing a product such as cookware specific heat well as health cost and ease of use our important factors to consider one of the materials tested which is the best suited for cookware and why explain based on safety/health cost specific heat and ease of use
Answer:
In short, the thermal conductivity of a material is how readily that material absorbs and transmits (releases) energy. When the fire or heating element of a range comes in contact to a pan, the energy from the heat source is transmitted to the pan. This increases the internal kinetic energy of the pan (commonly called "heating up"). The heated material then transmits the energy to nearby materials that are at a lower average molecular kinetic energy level (at a lower temperature than the material). The higher the thermal conductivity of the material, the faster it will heat up and also, the faster the heated area will spread to unheated areas of the same piece of material.
For example, if we placed a large sheet of stainless steel (fairly low thermal conductivity as cooking materials go) on a burner and turned on the burner, the area directly under the burner would get hot while the rest of the sheet slowly heats up. The burner imparts heat quickly only to the region of steel directly over it. The rest of the pan heats up from the conduction of the heat from that spot. When the outer edges of the sheet have reached a hot temperature, the spot directly over the burner would be extremely hot. The figure below shows an example of the temperature of the sheet of steel over a gas burner. The hottest parts are shown in white, hot is red and cool is blue.

9. Scientists are studying cellular respiration in a jungle ecosystem that has plants,
animals, and decomposers (which consume dead things). Which group or groups of
organisms in the jungle carry out cellular respiration?
plants
animals and decomposers
all organisms in the jungle
animals.
Answer:
all organisms in the jungle
Explanation:
Scientists are studying cellular respiration in a jungle ecosystem that has plants, animals and decomposers, so all organisms in the jungle carry out cellular respiration.
What is cellular respiration?Cellular respiration is a process in which organism use the oxygen molecule for the conversion of their food materials to get the chemical energy by the product of water and carbon dioxide.
This respiration process is done by all living organism like plants, animals, insects, bacteria, etc. to get energy for the other cellular functions. So, in the ecosystem of jungle plants, animals and decomposers all will perform cellular respiration.
Hence, option (c) is correct i.e. all organisms in the jungle.

List four factors that affect precipitation
Topic scowmce
Precipitation.
Humidity is the amount of water vapour in the air. This is produced by the evaporation
of water from oceans, lakes, rivers, wetlands and plants.
When water evapour in the air cools, it condenses. In other words, it becomes liquid and
forms little drops. These droplets form clouds.
When the droplets are small, they remain suspended in the atmosphere. But they often
become colder and their size and weight increases When they become too heavy to
remain suspended in the air, they fall to the Earth’s surface. We call this precipitation,
which may be rain, snow or hail.
Factors affecting precipitation.
Different areas of the Earth’s surface receive different amounts of precipitation.
Latitude: it rain more in the areas near the equator than in the temperature
zones and polar regions. The temperature is higher near the Equator so there is
more evaporation.
Altitude: it rains more in high areas than in low areas.
Level of humidity: it rains more on the coast than inland. Seas are a source of
humidity.
Precipitation is measured in millimeters (mm) per square matre.
An effective treatment for some cancerous tumors involves irradiation with "fast" neutrons. The neutrons from one treatment source have an average velocity of 3.5×107 m/s. If the velocities of individual neutrons are known to within 2.0% of this value, what is the uncertainty in the position of one of them?
Answer:
4.54 * 10^-14 m
Explanation:
From Heisenberg's uncertainty principle, we can write;
Δp.Δx ≥ h/4π
Given that;
Δp =Δmv
So;
Δmv.Δx ≥h/4π
Δmv =2/100(3.5×10^7 m/s * 1.66 * 10^-27)
Δmv =1.162 * 10^-21 Kgms-1
Δx ≥6.63 * 10^-34 /4 * 3.142 * 1.162 * 10^-21
Δx ≥4.54 * 10^-14 m

2. Consider the table of boiling points and structural isomers. Note that butane has two possible isomers but that decane has 75 possible isomers. Why does the number of possible isomers go up with an increasing number of carbon atoms?
Answer:
because the number of constitutional confirmation , and geometric isomers goes up with each carbon atom added there are many more possible configurations and connectivities possible with decane , a 10 carbon chain , than with butane, a 4 carbon chain
"The number of possible isomers go up with an increasing number of carbon atoms because as the number of carbon atoms increases the tendency to form branching with other carbon atom increases as well."
What is isomer?
Isomers are molecules or polyatomic ions that have the same molecular formulas that is, the identical number of atoms of each element but different atomic configurations in space. Isomerism refers to the existence or potential of isomers. Isomers don't have to have the same chemical or physical properties.
