Describe the energy transformation that must take place for a microwave to warm up a slice of pizza

Answers

Answer 1

Answer:

There is a whole bunch of energy trans formation taking place, layers and layers in fact:

First an elecric motor transforms electricity into kinetic energy and thermal energy.That motor turns a magnatron converting producing a specific band width of microwaves particularly well tuned to heating water molecules.

Those microwaves are doing all sorts of stuff:

Most are bouncing off the reflective surface of the fan blades attached to the motor/magnatron assembly and walls of the appliance but some of them are absorbed increasing the energy level and heat of the molecules of those surfaces (kinetic and thermal energy).

Then most of those bounced microwaves hit the food or food vessel the food is in. Some of those photons are absorbed being transferred to kinetic and thermal radiation at a new wave length and some go on their merry way.

Some of those microwaves pass by water molecules which, because water molecules have a polar charge, start spinning, causing transfer of em energy to kinetic energy and then kinetic energy to thermal energy. So again you get kinetic and thermal effects.

What give microwave cooking its unique characteristcs is the interplay between mucrowaves and water in the food. Microwaves are very, very efficient at heating water. So when you microwave food you are effectively steaming the food in its own juices.

Answer:

The Black Death

Explanation:

It goes by many names such as: The Black Plague, The Black Death, and The Bubonic Plague.

O, the Black Death, is the answer. The flea-borne bacteria Yersinia pestis was responsible for the European plague of the 1300s.

The Black Death was the name given to the European pandemic of the 1300s. It was a catastrophic pandemic that killed between 25 and 50 million people in Europe and Asia.

The bacteria Yersinia pestis caused the plague, which was spread by fleas that dwell on rats. The Black Death was a watershed moment in European history, and its ramifications may still be felt today.

When a ship from the Crimea docked in Messina, Sicily, in 1347, the plague arrived. The ship was transporting plague-infected rats, and the sickness swiftly spread throughout Europe. The fleas that resided on the rats transmitted the plague. When fleas bit humans, they spread the plague bacterium.

why wasn’t islam immediately accepted?

Answers

Answer:

I am a muslim so I can explain things, not fully though 'cause im 14 years old.

Explanation:

so Islam was the last religion if you think about the Ibraham-religions, so most of the people thought that it was some kind of stories the Prophet Mohamed (PBUH- peace be upon him). And one night, in that cave when the angel came, and his life in this world would never be the same. So he went home and told his wife Khadija about it, she believed him and thats why she's called "The first Muslim. so there is still people around that started getting mad at the prophet because he didnt belive in that statues of stone at that time, everyone was praying for.

if you think about nowadays Islam is one of the fastest growing religions, there is many 'islamofobic' people of course. some people say that Islam is just making the man having more rights than a woman but that's wrong. Islam is just keeping their woman safe from everything outside.

I hope you understand, I am in a hurry and didn't put much effort in it. but remember Islam wasn't accepted cause they thought the prophet lied. have a nice day ❤

Short paragraph on how women got the right to vote

Answers

Answer:

Beginning in the 1800s, women organized, petitioned, and picketed to win the right to vote, but it took them decades to accomplish their purpose. Between 1878, when the amendment was first introduced in Congress, and August 18, 1920, when it was ratified, champions of voting rights for women worked tirelessly, but strategies for achieving their goal varied. Some pursued a strategy of passing suffrage acts in each state—nine western states adopted woman suffrage legislation by 1912. Others challenged male-only voting laws in the courts. Some suffragists used more confrontational tactics such as picketing, silent vigils, and hunger strikes. Often supporters met fierce resistance. Opponents heckled, jailed, and sometimes physically abused them.

By 1916, almost all of the major suffrage organizations were united behind the goal of a constitutional amendment. When New York adopted woman suffrage in 1917 and President Wilson changed his position to support an amendment in 1918, the political balance began to shift.

On May 21, 1919, the House of Representatives passed the amendment, and 2 weeks later, the Senate followed. When Tennessee became the 36th state to ratify the amendment on August 18, 1920, the amendment passed its final hurdle of obtaining the agreement of three-fourths of the states. Secretary of State Bainbridge Colby certified the ratification on August 26, 1920, changing the face of the American electorate forever.

Describe how the Triassic period was a transitional time period during the Mesozoic
era. Explain why the boundary between the Triassic and Jurassic periods are similar to the boundary between the Permian and Triassic periods.

Answers

Answer: The Triassic period was a transition from the Mesozoic to the Paleozoic Era. It ranges from 254 mya to 206 mya between the end of the Permian period and the beginning of the Jurassic. The Triassic had a special climate and biota indigenous to that time, as with almost every other era of the Earth's history. Tectonic occurrences that have never occurred before or since have largely affected the paleoclimate.The land masses of the planet were still bound together in the vast supercontinent known as Pangaea at the beginning of the Triassic period. In the mid-Triassic, Pangaea started to break up , forming Gondwana in the south (South America, Africa , India, Antarctica, and Australia), and Laurasia in the north (North America and Eurasia). The displacement of the two resulting supercontinents was caused by the sea floor spreading between Gondwana and Laurasia on the midocean ridge at the bottom of the Tethys Sea, the body of water. As Pangaea was breaking up, by subducting the ocean plates underneath the continental plates, mountains were rising on the west coast of North America. The mountain formation persisted along the shore from Alaska to Chile in the Middle to Late Triassic. As mountains were forming in the Americas, the expanding rift separated North Africa from Europe. This separation of the continents progressed further westward, separating eastern North America from North Africa finally. Pangaea was affected by the climate of the Triassic period, its centralized location straddling the equator, and the geological activity associated with its breakup. Generally speaking, in relation to sea level, the continents were of high elevation and the sea level did not change significantly during the time. Because of the low sea level, there was no inundation of the continents to form shallow seas. Much of the inland region was isolated from the ocean's cooling and humid effects.The outcome was a globally arid and dry climate, while seasonal monsoons were most likely encountered in regions along the coast. There were no polar ice caps, and the north-south temperature gradient is believed to have been more gradual than today. As the divide between North Africa and Southern Europe developed, the sea level increased, resulting in the flooding of Central and Southern Europe; the terrestrial European climates were hot and dry, as in the Permian. Overall, with gymnosperm forests, the ecosystem tends to include both arid dune ecosystems and wet river and lake habitats.Based on experimental studies, some conclusions may be made regarding more complex regional climates and organisms. The presence in the high northern and southern latitudes of coal-rich sequences, as well as the presence there of large amphibians, suggests that in those regions the paleoclimate was wetter. Living populations of certain Mesozoic ferns (including the Osmundacae and Dipteridacae families) now live under forest canopies in wet, shady areas, so it is possible that the paleoclimates populated by their Triassic ancestors were still damp and shaded. There may also have been large , open areas of low-growing vegetation in the Mesozoic period, including savannas or fern prairies with dry, nutrient-poor soil inhabited by herbaceous plants, such as ferns of the Matoniaceae and Gleicheniaceae families. Thus, the Triassic vegetation was very provincial, considering the union of the continental landmasses, although this deteriorated as the Triassic wore on.Conifers, ginkgos, cycads, and bennettitaleans dominated the northern forest at the beginning of the Triassic, while Dicroidium and Thinnfeldia dominated the forests of Gondwana. Both hemispheres gave way to coniferous and cycad plants by the end of the Triassic. The Triassic-Jurassic boundary is close to the Permo-Triassic boundary in that, while a massive extinction of terrestrial vertebrates occurred, the global ecosystem was not drastically altered. Pangaea began to split up with the end of the Triassic and the beginning of the Jurassic, eventually impacting the atmosphere, but not as dramatically as it had during the Triassic.
