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.

How does geography affect where people settle?

Answers

Geography is a very important part of choosing where you would like to settle. There are many components that factor into everyday life that are very important, like agriculture, food, and climate.

The climate is different in different parts of the world. For example, if you prefer cold climates you would settle up North, but if you were to prefer hotter climates you would most likely settle in the South. The climate also changes the soil and farming.

Due to the warmer climate, soil in the South is richer and better for agricultural purposes. This was why the South was more focused on farming and agriculture, while the North got their income from industrialization.

Different animals and plants are in different regions as well. Different species of animals will reside in different areas and different plants may prefer certain climates.

If you are planning on farming, you will prefer very large flat plains. If you plan to live in the mountains you may live somewhere bumpy and rocky.

According to Reverend Perkins, what caused the Whitman Massacre? What is his point of view on this historical event?
Does evidence from Narcissa Whitman's diaries support Perkins's argument? Write one or two paragrapha in response, and

Answer:

Dr. Marcus Whitman (1802-1847), his wife Narcissa Prentiss Whitman ... The attack, a pivotal event in Northwest history, will lead to a war of retaliation ... "He wanted to see the country settled," wrote Reverend Henry K. Perkins ... Tribal leaders made several efforts to get the Whitmans to leave, to the point of

Explanation:

During several days of violence, most of it on the first day, Dr. Marcus Whitman (1802-1847), his wife Narcissa Prentiss Whitman (1808-1847), nine other men, and two teenage boys are slaughtered. Another guy makes it to Fort Walla Walla, but is thought to have perished soon after, making him the fourteenth victim.

The attack, a crucial moment in the history of the Pacific Northwest, will result in a war of reprisal against the Cayuse and the expansion of federal authority over the modern states of Washington, Oregon, and Idaho as well as portions of Montana and Wyoming.

What do you mean by the Whitman Massacre?

The Whitman Massacre occurs on November 29, 1847, when a small band of Cayuse Indians attack the Whitman Mission close to Walla Walla.

The Cayuse began to distrust Whitman when a measles epidemic caused the death of half of the native population and more sick indigenous than white immigrants.

The Quartering Act introduced in 1765 by the British Parliament in America.

Many colonists, treated soldiers badly. Colonist cannot go against the Act if found, punished by British officers.

If a British soldier showed up at my house needing a place to stay I will politely refuse to accept it. If he insists, I will be civil to him and provide him home and food.

why the Bronze Age Indus Valley Civilization (3300-1300 BCE)
flourished around 3,000 B.C.E.

Answers

Answer:

Explanation:

La cultura del valle del Indo fue una civilización de la Edad del Bronce, que se desarrolló desde alrededor del 3300 a. C. hasta 1300 a. C. a lo largo del valle del río Indo, en Afganistán, Pakistán y el noroeste de la India. Abarcó cerca de un centenar de asentamientos y dos ciudades importantes: Harappa y Mohenjo-Daro, ambas en Pakistán. En conjunto, comprendió el área más extensa de todas las civilizaciones antiguas, más de un millón de kilómetros cuadrados, y atravesó varios periodos, siendo su máximo esplendor entre el 2600 y el 1900 a. C.

Al igual que las civilizaciones de Mesopotamia y Egipto, dependía de su río. Como el Nilo, el Indo se desbordaba todos los años, inundando extensas zonas y depositando sedimentos fértiles. Este inmenso potencial agrícola fue la base sobre la cual se desarrolló el urbanismo en torno al río Indo.

Con las culturas prehistóricas del valle del Indo se prepara el primer capítulo de la historia de la India. Se trata de un largo periodo prehistórico, probado por testimonios líticos. Por otra parte, se pueden encontrar vestigios prehistóricos hasta el I milenio a. C., es decir, hasta un tiempo en que la península ya había entrado en la historia. En sentido estricto, las culturas del Indo pertenecen a la prehistoria ya que solamente han dejado restos arqueológicos sin documentos literarios, pero para apreciar la historia india hace falta tomar en consideración estas culturas urbanas prearias.

Insure foreign tranquility is not a  reason given for the establishment of the Constitution. Option E is correct.

What is the significance of constitution?

A constitution is vital because it guarantees that individuals who make decisions on behalf of the people do so fairly. It also outlines how those in positions of power can be held accountable to the people they serve.

It determines citizens relationships with governments. It safeguards and guarantees all people fundamental rights. It specifies how the Government will be elected, as well as who will have the authority and responsibility to make important decisions.

The constitution provides for the public's common defense. It makes the union more complete, promotes the general welfare, establishes justice, and secures the benefits of liberty.

Therefore, The foundation of the Constitution was not done to ensure foreign tranquility. So, option E is correct.
