What is the relationship between heat production and resistance as related to electricity?

Answers

Answer 1

Answer:

Heat produced is directly proportional to resistance

Explanation:

Heat produced is directly related to the resistance if resistance will be more then heat production will also be more

The heat in produced is given by [tex]H=i^2RT[/tex], here i is current, Ris resistance and T is temperature.

From the relation we can see that heat is directly proportional to resistance so if we increase the resistance  then heat produced also increase and if decrease the resistance heat produced decreases.

A. The Earth moves slightly closer towards and further away from the Sun throughout the year

B. The Earth is tilted relative to the ecliptic

C. The Earth is mostly covered in water

Answers

Answer:

B. The Earth is tilted relative to the ecliptic

Explanation:

Its due to the earth has an axial tilt of 23.5 degrees which is an inclined motion, relative to the orbital plane of rotation. This is the angle of obliquity of the earth from its center. For this reason, the earth has solstice in summer, winter, vernal and equinoxes and owning to the fact that the continents in the north have winter in the Northern hemisphere and continents in the south have summer. Without this tilt, the earth would have climatic extremes. Day and night time of the earth are also influenced by the same rotational motion.

Answers

Answer:

Glycogen

Explanation:

Animals, including humans store this glucose fat in their cells, which are quickly available for energy. The excessive is stored in the liver, if you consume some extra carbohydrates the body stores the excess in the form of glucose. Mostly consisting of protein that comes from food about 300g per day. Human glucose is metabolized by glycolysis. The use of glucose in the cell in energy form is either by aerobic respiration, food sources of glucose can range from fruits, vegetables, and pulses. In plants, glucose is a product of photosynthesis also known as starch.

The stored form of glucose in the body is called glycogen.

In animals including humans, glucose is primarily stored as glycogen. It is a polysaccharide made up of numerous glucose molecules connected by branches. In order to meet the body's energy needs during fasting or physical activity, the liver and muscles store glycogen. Glycogen undergoes glycogenolysis when blood glucose levels fall dissolving into individual glucose molecules to provide energy.

In contrast a process known as glycogenesis transforms extra glucose into glycogen during times of high blood sugar such as right after eating. This dynamic control of glycogen synthesis and breakdown keeps blood sugar levels stable and gives the body a ready source of energy.

An Fm radio station broadcasts at 85 megahertz(MHz) What is the energy of each photon in Joule? Use h=6.6 x 10 to the 34th Js for the Planckconstant

Answers

Final answer:

Each photon from an FM radio station broadcasting at 85 MHz has an energy of approximately 5.61 × 10^-26 joules, calculated using Planck's constant and the frequency of the photon.

Explanation:

To find the energy of a photon in joules from an FM radio station broadcasting at 85 MHz, we can use the equation E = hf, where h is Planck's constant and f is the frequency of the photon. Planck's constant (h) is given as 6.6 × 10-34 joule seconds (Js), and the frequency (f) is 85 MHz, which is 85 × 106 hertz (Hz).

In this case, the energy (E) of each photon can be calculated as follows:

E = (6.6 × 10-34 Js) × (85 × 106 Hz)

E = 5.61 × 10-26 joules

Thus, each photon from an FM radio station broadcasting at 85 MHz has an energy of approximately 5.61 × 10-26 joules.

why can't high quality energy resources such as oil be recycled?

Answers

Answer:

Oil is one of the most efficient and widely used energy resources. These are fossil fuels. When the ancient plant and organisms dies they accumulates at the bottom of the seas, which are then covered by the sediments such as mud and sands, forming various rock layers. These trapped organisms an plants after millions of years turn into fossils, by undergoing the fossilization process. These are non-renewable energy resources or conventional sources of energy. In addition to oil, coal, petroleum and natural gas are also some examples of non-renewable energy.

Thus, the high quality resources or energy such as oil, petroleum and natural gas cannot be recycled.

As these winds have a problem with the Coriolis force that is the rotation of the earth on its axis. Occurring in mid-latitudes aloft the air currents. This balance does not occur near the surface since the friction force is significant. The geostrophic winds develop in a well-defined layer of air i.e either hot or cold. In a geostrophic flow of water bodies instead of the winds moving from high to low pressure, due to the rotation of the earth. The major current sin the ocean like Gulf stream and Kuroshio, and Agulhas current are all approximation and examples of geostrophic current.

What types of geologic evidence support the existence of Pangaea?
What type of geologic evidence provides the greatest support for the hypothesis that the eastern coast of North America once joined with the western coast of Europe?
How do you think Wegener’s background as a climatologist contributed to his hypothesis that the continents were once joined?

Answers

Answer:

Evidences suggested are given below

Explanation:

Evidence given in support of the existence of Pangaea was given in Plate tectonic theory by Alfred Wegener.

1. The Jigsaw fit puzzle

2. Glacial ranges and mountain chains on various continents.

3. Formation and age of rocks, in southern hemispheres  

4. Flora and Fauna evidence  

Apart from this poleward moving forces and forces of the sun and the moon gravity and west wind drift have seen to be responsible for the formation of hypotheses.  As he stated that the continent of South America and Africa were once part of the same Gondwana landmass, Similarly the North America eastern side and Western side of Europe were the same as the ones that were part of the Lurata i.e Northern super landmass. This can be found in the evidence given in the paleomagnetism theory. Wegener believed that the continental crust is formed from the slabs and these slab or plates are lighter in weight and float on thick liquid asthenosphere oceanic crust with the help of winds and ocean currents. Thus he concluded that rocks were once part of the supercontinent that broke with the move
Final answer:

Geologic evidence for Pangaea includes matching rock layers, fossils, and glacial evidence. The hypothesis of the eastern coast of North America joining with the western coast of Europe is supported by fit, fossils, and rock structures. Wegener's climatology background helped him notice similarities in climate and geological features across separated continents.

Explanation:

Geologic evidence supporting the existence of Pangaea includes matching rock layers across continents, fossil evidence of similar plants and animals found in different continents, and glacial evidence including striations and till deposits.

The hypothesis that the eastern coast of North America once joined with the western coast of Europe is supported by fit of the continents like puzzle pieces, fossil evidence of similar plants and animals, and matching rock structures.

Alfred Wegener's background as a climatologist contributed to his hypothesis by observing that areas with similar climates, such as coal deposits in Antarctica, existed on continents that are now widely separated. This led him to consider the idea of continental drift, suggesting that these areas were once connected.

A particle called the pi-meson is made from an up quark and an antidown quark. What is the charge of this particle?

Answers

Final answer:

The pi-meson, composed of an up quark and an antidown quark, carries an overall electric charge of +1 because the charges of its constituent quarks sum to +1.

Explanation:

A pi-meson is composed of an up quark and an antidown quark. Quarks are subatomic particles that each carry a fractional electric charge. Specifically, an up quark carries a charge of +2/3, while an antidown quark - being the antiparticle of a down quark - carries a charge of +1/3.

The total charge of a particle is the sum of the charges of its constituent parts. Therefore, to find the charge of the pi-meson, simply add together the charges of the up quark and the antidown quark.

In the case of the pi-meson (up quark, antidown quark), the total charge is (+2/3) + (+1/3) = +1. Thus, a pi-meson has an electric charge of +1.

EXPLAIN HOW METAMORPHISM CAN ALTER A ROCK CHEMICALLY AS OPPOSED
TO MINEROLOGICALLLY.

Answers

Answer:

The rocks are comprised of cracks and fractures in between the sediments and mineral grains that have the capacity to store fluid in them. This fluid is generally the water that contains various types of dissolved ions. These fluids in the rocks are very much important because the chemical reactions that take place include the change in mineral from one type to another new type. This can highly increase the amount of dissolved ions that are dissolved and transported by the water. This alteration of rock that occurs chemically due to these fluid refers to the process which is commonly known as the metasomatism. Whereas, the rock alters mineralogically due to the increasing temperature and pressure condition, that changes the grade of rocks.

This is how metamorphism alters the rock chemically in comparison to mineralogically.

Vertical mixing only occurs in b) Troposphere

Explanation:

The troposphere is the sphere that is characterized by vertical mixing of air masses and air currents. As a result of the turbulence created in top layers of air. Here the uneven heating and cooling of land and oceans create convection currents to rise upwards and create up and downward movement of with environmental lapse rate and averages 6.5 ºC/km. This helps to push the troposphere boundary upward. The planetary boundary of motion creates such type of layer of air that moves through the poles and rising air stop at the tropopause as its the region or zone of mixing of air currents as all convective activity stops here.

The principles of constant proportions in chemistry state that a compound will always have the same proportion of elements by mass. This means that the ratio of the masses of the elements in a compound will always be the same, regardless of the amount of the compound.

When it comes to salt in seawater, the principles of constant proportions mean that no matter where you sample seawater from, the ratio of sodium to chloride ions will be the same. This is because the composition of salt (sodium chloride) in seawater remains constant.

https://brainly.com/question/31704267

#SPJ6

Final answer:

The principle of constant proportions states that the elements in a pure chemical compound are always combined in the same proportion by mass. This principle applies to the salt in seawater, which is primarily Sodium Chloride, with a consistent proportion of Sodium and Chloride. It is also exemplified in the way certain salt-loving microorganisms thrive in constant salt conditions, and in the solubility equilibrium of salt in seawater.

Explanation:

The principle of constant proportions, also known as the law of definite proportions, states that in a pure chemical compound, the elements are always combined in the same proportion by mass. This principle applies to seawater and its salt content. Salt in seawater is primarily Sodium Chloride (NaCl). Regardless of the location, the proportion of Sodium and Chloride in Sea Salt is always nearly constant, approximately 39.34% Sodium and 60.66% Chloride by mass.

For example, the principle is evident in the way certain microorganisms called halophiles ("salt-loving") thrive in marine environments where salt concentrations hover at 3.5%. Extreme halophilic organisms, like the red alga Dunaliella salina and the archaeal species Halobacterium, can even survive in hypersaline lakes such as the Great Salt Lake or the Dead Sea, which are several times saltier than the ocean.

Another facet of this principle can be seen in how solubility products work. The solubility of a substance, such as salt in seawater, can vary from essentially zero to infinity, producing saturated solutions when the solubility limit is exceeded. The equilibrium between the dissolved and undissolved salt is also part of this principle of constant proportions.

describe different types of volcanoes, how do they form? can volcanoes change the climate if so how? can volcanic eruptions be predicted why?

Answers

Answer:

There are mainly 4 types of volcanoes.

Explanation:

1. Cinder cones: They are a bowl-shaped crater,  build from particle or blobs of congealed lava that is ejected from a single gas vent, as the air is broken into small fragments that are solidified and falls as cinders.

2. Composite volcanoes: stratovolcano or composite cone are those that form a steep-sided, symmetrical cone of large dimensions built around by lavas. Some examples are Mount Shasta in California, Mount Hood in Oregon.

3. Lava domes: There internal structure is defined by bulbous masses of lava, that are too vicious.

4. Shield volcanoes: These are built entirely by fluid lava, and flow p[ours in all directions.

A volcano can change its surrounding weather patterns but not the climate of a place as a climatic zone is composed of stable and static atmosphere like that of poles, tropics, and temperate lands, etc.  

Not all volcanic eruptions can be predicted successfully as they are also triggered by an earthquake and the active or dominant type of volcano can be identified based on its previous eruption patterns.

Which of the following formulas would you use to convert a temperature initially taken in degrees Fahrenheit to degrees Celsius?

Question 57 options:

C = F – 273

C = 9/5F + 32°

C = 5/9(F - 32°)

C = 5/9F - 32°

Answers

Answer:

C = 5/9(F - 32°)

Explanation:

If we compare the farenheit degree scales with the celsius degree scale, we find that the intervals between the same reference points are 180 ° farenheit and 100 ° celsius. 180 degrees farenheit are needed to cover the same temperature range of 100 degrees Celsius. From this information the unit factors of temperature change can be established.

Factor: 1 °C/1.8°F= 5/9

Also, to convert from ° F to ° C, we must subtract 32 degrees farenheit to reach the zero point of the celsius scale.

Then, the correct formula is:

C = 5/9(F - 32°)

Consider the following production possibilities frontier model for an economy that produces only two goods: barley and tablets. Which of the following is true regarding this economic model? The fact that there are only two goods produced in this theoretical economy, when, in reality, economies produce many more types of goods, means this model is generally useless. This PPF is not an economic model. In order to construct such a model, an economist would need real life data regarding countries that only produce two goods. The fact that there are only two goods produced in this theoretical economy is a simplifying assumption that still allows economists to demonstrate key economic concepts. Read the passage from Edgar Allan Poe. In 1826, Poe became a student at the University of Virginia. Although Poe was an excellent student and did extremely well in Latin and French, he started gambling and went into debt. Poe later said that he began gambling because Allan would not give him enough money to pay for his expenses. After Allan refused to pay Poes gambling debts, Poe left the university and briefly returned home. In 1827, tired of quarreling with his foster father, Poe left Virginia for Boston, Massachusetts. Although Poe was no longer in school, he continued to write and published his first volume of poetry, Tamerlane and Other Poems, that same year. At eighteen years old, Poe was a published author, but he still needed to earn money, so he enlisted in the US Army. After serving for two years, Poe learned that his foster mother, Frances, was ill. He rushed to Richmond, Virginia, to see her, only to learn that she had died from tuberculosis before he could arrive. What is most likely the intended effect of including the historical details about Poes struggles? to persuade the reader to feel sorry for Poe because of his difficult life to use Poes own words, thoughts, and feelings to fully characterize him to emphasize the central idea that Poes difficult life influenced his writing to paint a picture of the setting so that the time period is vivid to the reader n May 1, 2009 Giltus Advertising Company received $1,500 from Julie Bee for advertising services to be completed April 30, 2010.

The measure of the angles of a triangle are x, 2x, and 3x.Whatare the measures of the angles of the triangle ? Which is an example of region?A China and EnglandB New York City's skylineC the world's largest fresh water lakeD twenty countries whose people share a common religion and cultural heritage I WILL GIVE BRANERLIST AND 15 POINTS A small box is held in place against a rough vertical wall by someone pushing on it with a force directed upward at 27 above the horizontal. The coefficients of static and kinetic friction between the box and wall are 0.40 and 0.30, respectively. The box slides down unless the applied force has magnitude 18 N. What is the mass of the box in kilograms? Magnetic field is measured in SI units of a tesla (T), and a current through a wire generates a field around the wire. The largest fields that we can make with most normal conducting materials carrying current are limited by the resistance of the wire and are around 1 tesla. For comparison, Earth's magnetic field is roughly 50 micro tesla You may have heard of a field unit called a gauss. It takes 10,000 G to make 1 T. What would be the maximum force on a wire 0.1 m long carrying a current of 80 A in a uniform magnetic field of 1 T? 8 N when the wire is perpendicular to the field80 N when the wire is perpendicular to the field8 N when the wire is parallel to the field80 N when the wire is parallel to the field
