Which of the following is most likely to be a conductor

Answers

Answer:

A compound containing metallic bonds.

Explanation:

Metals are the best conductors of electricity due to their free-moving electrons, with silver and copper being among the most effective. Copper is widely used for electrical wiring, while silver's use is limited by its cost. Gold is also a good conductor, used where high conductivity is necessary.

The substance most likely to be a conductor is typically a metal because metals have free electrons that can easily move and carry electric current. Among the best conductors of electricity are silver, copper, gold, and aluminum, which are also excellent thermal conductors.

Copper is commonly used in electrical wires due to its high electrical conductivity and cost-effectiveness. However, the best electrical conductor is actually silver; its usage is limited by its high cost. Gold is also used for its high conductivity, especially when high conductivity is required, such as in high-quality audio cables or in electronic connectors that are subjected to heavy wear.

In the case of cooking utensils, they are typically made from good conductors like these metals to efficiently transfer heat. These conductors work well because they have a high density of free electrons that are available to carry the electric charge, resulting in low resistivity. Conversely, insulators have a high resistivity and semiconductors have an intermediate resistivity, with their conductivity varying depending on impurities and other factors.

If angle ABE = 2n + 7 and angle EBF=4n-13,
find angle ABE.​

Answers

Answer:

The measure of angle ABE is 27°.

Explanation:

Consider the below figure attached with this question.

Given information: ∠ABE=2n+7 and ∠EBF=4n-13.

From the below figure it is clear that ∠ABE and ∠EBF are congruent.

[tex]m\angle ABE=m\angle EBF[/tex]

[tex]2n+7=4n-13[/tex]

Isolate variable terms on one side.

[tex]7+13=4n-2n[/tex]

[tex]20=2n[/tex]

Divide both sides by 2.

[tex]10=n[/tex]

The value of n is 10.

We need to find the measure of ∠ABE.

[tex]\angle ABE=2(10)+7=20+7=27[/tex]

Therefore, the measure of angle ABE is 27°.

The measure of angle ABE is 27°.

Since the angles are congruent, therefore, ∠ABE=2n+7 and ∠EBF = 4n-13 will be equated to each other.

This will be;

2n+7 = 4n-13

Collect like terms

4n-2n = 7+13

2n  = 20  

Divide both sides by 2.  

2n/2 = 20/2

n = 10  

Therefore, the value of n is 10.

Since angle ABE = 2n + 7

ABE = 2[10]  + 7

= 20 + 7 =  27°.  

Therefore, the measure of angle ABE is 27°

When a turtle is lying on a sunny riverbank,how is it’s body temperature affected when it starts swimming in a cool river

Answers

Answer:

When a turtle is lying on a sunny riverbank, it’s body temperature rises and when it starts swimming in a cool river, it's body temperatures drop.

Explanation:

Cold-blooded animals, like turtles, do not have an internal feedback loop that regulates constant body temperature – as warm-blooded animals do. Their body temperatures fluctuate with that of the environment. This is why you see animals like lizards basking on rocks to raise their body temperatures. When it too hot, then they seek the shade under these rocks to lower their temperatures.

which trait is most likely a result of artificial selection

Answers

Answer:

Explanation:Artificial selection is distinct from natural selection in that it describes selection applied by humans in order to produce genetic change. When artificial selection is imposed, the trait or traits being selected are known, whereas with natural selection they have to be inferred. In most circumstances and unless otherwise qualified, directional selection is applied, i.e., only high-scoring individuals are favored for a quantitative trait. Artificial selection is the basic method of genetic improvement programs for crop plants or livestock (see Selective Breeding). It is also used as a tool in the laboratory to investigate the genetic properties of a trait in a species or population, for example, the magnitude of genetic variance or heritability, the possible duration of and limits to selection, and the correlations among traits, including with fitness.

Wheat plants that produce much larger grains are most likely a result of artificial selection. Therefore, option C is correct.

What do you mean by artificial selection ?

Artificial selection, also known as "selective breeding”, is where humans select for desired traits in agricultural products or animals, rather than leaving the species to germinate and alter gradually without human interference, like in natural selection.

Agriculture has traditionally utilised artificial selection to breed crops and animals with desired features. Today's meats are the result of carefully bred birds, cattle, sheep, and pigs.

By artificial selection, several fruits and vegetables have been enhanced or even invented.

What are Earth's plates?

Tectonic plates are massive chunks of the Earth's crust and upper mantle. They are composed of oceanic and continental crust.

Earthquakes occur near mid-ocean ridges and large faults that mark the plate boundaries.

The hot magma flows in convection currents due to tremendous heat and pressure within the earth. These currents usually result the tectonic plates that make up the earth's crust to move.

The Earth's tectonic plates are constantly shifting. Heat within the Earth drives their movement.

Explanation:

Data Given:

                Mass of O₂  =  16.0 g

                M.Mass of O₂  =  32.0 g.mol⁻¹

Step 1: Calculate Moles of O₂ as,

                Moles  =  Mass ÷ M.Mass

Putting values,

                Moles  =  16.0g ÷ 32.0 g.mol⁻¹

                Moles  =  0.50 mol of O₂

Step 2: Calculate number of Carbon atoms,

As 1 mole of any substance contains 6.022 × 10²³ particles (Avogadro's Number) then the relation for Moles and Number of Oxygen Molecules can be written as,

      Moles  =  Number of O₂ Molecules ÷ 6.022 × 10²³ Molecules.mol⁻¹

Solving for Number of C atoms,

      Number of O₂ Molecules  =  Moles × 6.022 × 10²³ Molecules.mol⁻¹

Putting value of moles,

      Number of O₂ Molecules  =  0.50 mol × 6.022 × 10²³ Molecules.mol⁻¹

      Number of O₂ Molecules  =  3.011 × 10²³ OMolecules

A. The oceans evaporate

B. a rock falls off a cliff

C. rain runs down a mountain and into the river which eventually makes it's way to the ocean.
D. A volcano erupts and throws gas into the atmosphere.

Answers

Explanation:

(1)

True

The winds are significant in the distribution of heat across the globe. There are global air circulations around the world such as the Hadley and polar cells that take heat from the hotter regions to the cooler regions. This is driven by high and low-pressure systems on earth that are influenced by the sun. Cooler air masses move from the high-pressure system and displace the warm winds in the low-pressure systems. This helps in maintaining a heat balance on earth.  

(2)

False

The geosphere not only includes all the rocks on the surface of the earth but also the whole of the lithosphere ( or crust), which also includes all the landforms on earth. All the rocks and minerals in the interior of the earth are also part of the geosphere, including the process – such as the convection currents of the mantle- that helps in the shaping of the earth's surface.

(3)

A.

In a storm, the heat from the hydrosphere which is transferred to the atmosphere via the heat of evaporation is what feeds the storm. Therefore these two spheres not only share distribution of heat energy but also water. When the storms dissipate the heat and its water from the clouds, the water flows back to the hydrosphere and the cycle continues.

(4)

True

The biosphere includes all the living and biotic components on earth. Therefore even the marine animals in the oceans are part of the biosphere. They are one aspect that signifies the interaction betwene the hydrosphere and the biosphere. These organisms draw oxygen, water and minerals from the hydrosphere which is important or life.

(5)

True

However, the atmosphere is not the only sphere that distributes heat across the globe. So does the hydrosphere. The ocean's currents are very significant with this regard just as are air currents, The warm surface currents from the equator distribute heat towards the poles while cooler deeper currents  flow towards the equator from the poles – maintaining a heat balance on earth.

(6)

D.

When a volcano erupts, gases  -like sulfur dioxide and carbon dioxide- and pyroclasts from deep in the earth rocks (geosphere) are spewed into the atmosphere. This is an example of how these two spheres of the earth interact.

Environmentalb. Distractionsc. Vehicle conditiond. Impairment Matter with a density that is less than water will____ when placed in a container of water? John performs an experiment on an electric circuit. He increases the voltage from 25 volts to 50 volts while keeping the resistance constant. What will be the effect of John's changes on the current? The range for a list of measurements equals the greatest measurement minus the least measurement. The two lists of measurements, X and Y, combined consist of 30 measurements with a range of 25. What is the range for the measurements in list X? Learning Goal: How do 2 ordinary waves build up a "standing" wave? A very generic formula for a traveling wave is: y1(x,t)=Asin(kxt). This general mathematical form can represent the displacement of a string, or the strength of an electric field, or the height of the surface of water, or a large number of other physical waves!Part C Find ye(x) and yt(t). Remember that yt(t) must be a trig function of unit amplitude. Express your answers in terms of A, k, x, , and t. Separate the two functions with a comma. Use parentheses around the argument of any trig functions.Part E At the position x=0, what is the displacement of the string (assuming that the standing wave ys(x,t) is present)? Part G FromPart F we know that the string is perfectly straight at time t=2. Which of the following statements does the string's being straight imply about the energy stored in the string?a.There is no energy stored in the string: The string will remain straight for all subsequent times.b.Energy will flow into the string, causing the standing wave to form at a later time.c.Although the string is straight at time t=2, parts of the string have nonzero velocity. Therefore, there is energy stored in the string.d.The total mechanical energy in the string oscillates but is constant if averaged over a complete cycle. Question 4:Gregory is x years old. Daisy is 2 years older than Gregory. The sum of their ages is 40.(a) Form an equation in terms of x.(b) Solve the equation and work out Gregory's and Daisy's ages. Organism in kingdoms archaebacteria live in environments that are very hot or very cold Which other characteristics is common to organisms in this kingdom Student 1 said,Magnetic force and electric charges are similar, becauseopposites attract and likes repel.Student 2 said,Magnetism and electricity are similar because they both havea force field extending out from them so they dont have totouch to work.How would you respond to these students? From In Memoriam, A. H. H. by Alfred, Lord Tennyson Far off thou art, but ever nigh; I have thee still, and I rejoice; I prosper, circled with thy voice; I shall not lose thee though I die.Earlier in the poem, the speaker expresses his grief over the loss of his friend. Why does he, in these later lines, "rejoice"?Visiting places where his friend spent time, the speaker imagines that his friend is still present.By memorializing their friendship in the poem, the speaker feels that his friend lives on.The speaker believes that he and his friend, although physically separated, are united spiritually.
