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.
Explanation:
There are different kinds of Music. The article shows that a lot of genres of American music have come into existence as a result of African-American songs in all of history.
<h3>How American music is African American music?</h3>
African-American music is known to be the framework that covers the diverse scope of music and musical genres that has been developed by African Americans.
Their origins are said to be from musical forms that came about as a result of the historical condition of slavery that that is the order of the day for the lives of African Americans before the American Civil War.
The music of the United States depicts the pluri-ethnic population of the country through a wide scope of styles.

Answer:
Hello there! After the coup d'état in Spain, Agustin de Iturbide proclaimed:
<em>a) Mexico's independence and made himself emperor</em>.
Explanation:
Agustin de Iturbide was a soldier and politician who fought against the insurgent's beliefs of independence in Mexico.
But the political change in Spain of 1820 affected the Mexican aristocrats, and he had to change his beliefs by the last years of the war.
During the war, Iturbide stood out both militarily and politically and became an attractive candidate to take the power.
He took the power on 1822.
Answer:
due to installment buying of manufactured goods
Explanation:
Metal workers made tools and weapons from copper and later bronze Bronze: a mixture of copper, tin, and sometimes other metals like zinc. Bronze tools and weapons were stronger than copper ones. Most of the time they sold the bronze <span>tools which helped other groups win battles.</span>
