Amalgamation is the process through which feudal societies were developed.
Explanation:
Powerful monarchs gained huge power by occupying the provinces of the feudal lords. They controlled the territories and nations as well as the empires.
As a result the power of the monarchs and the parliament increased and the power decreased in case of barons.
Thus the creation of the national government took place in England, Spain, France and United Kingdom. Later in the German states. Through the ability to remove the politicians lot of leverage was enjoyed in many nations.
Answer:
d) Chemical composition of its outer regions
Explanation:
Spectroscopy is the study of spectral lines, it's an important part of studying the chemistry that goes on in stars and interstellar clouds, spectral lines can give relevant information because every atom or molecule gives off light at a specific frequency, thus, astronomers can look for gas containing a particular atom or molecule by tuning the telescope to one of the gas's characteristic frequencies. Therefore, we can know the chemical composition or a star's outer regions analyzing the spectral lines.
Even though the spectral shape of a blackbody continuum depends on the temperature of the object an there's a relationship between an object’s temperature and the peak of its spectrum, we don't consider this answer as correct because we are not measuring spectral lines but the continuum.
I hope you find this information useful and interesting! Good luck!
The study of geography is important because it helps you learn about your surrounding area. Depending on where you live it might be ideal to know where there are hills and high elevations in case of extreme flooding. In that case you could easily get to some safety if you are on the road. If you hadn't know then you would be in a major predicament.
Answer:
The Panama canal
Explanation:
Opened in 1914, the Panama canal allows maritime traffic to travel between the Pacific and Atlantic oceans very rapidly through a system of locks (2 on the Pacific side, one in the Atlantic side), and the boats pass through an artificial lake crossing the whole country of Panama.
It takes just a few hours to cross from one side to the other, while it would take weeks to go down to the tip of South America and back up.
In 2016, the canal opened new locks, that can receive larger boats.
