Answer:
c. the Sun
Explanation:
Considering the description made in the question about the atom of a lead with atomic number 82, the place t his atom probably have NOT been during the course of its existence is the SUN
The reason is that SUN is believed to consist of ten significant elements, which are: Hydrogen, Helium, Oxygen, Carbon, Nitrogen, Silicon, Magnesium, Neon, Iron, and Sulfur.
Also, some of the properties of lead show that it won't have existed in the Sun before. For example, it is a poor transmission of heat. Also, it doesn't react with oxygen in the air and doesn't burn as well.
There are multiple reasons for this. First of all, water is available in almost every place on the Earth. It doesn't pollute the air, doesn't cause health use and is easily handle.
Other factor is the fact that water has a really high specific heat. This means that water, and more specifically steam, can aborb and transport more energy. A lower heat capacity would imply the need to boil more of the liquid to obtain the same amount of energy. This combine with the fact that water expands at a large rate when boiling, combine with everything mentioned previously, and you get a liquid with all the characteristics that a efficient turbine requires to work.
Answer: B
The only difference between these different types of radiation is their wavelength or frequency

You were able to access the internet to post this question because of science. Medicine or vitamin supplements you take are a result of science. You use soap to wash your hands because of our understanding of how germs work, which is science. Practically anything you can think of has come about through the achievements of science. <span>Image formation (due to phenomenon of reflection). </span><span>Mirage (Its a everyday thing in deserts due to refraction) </span>

Two segments of a comet are head and tail.
Head is main part of comet. Depending on how comet was created head can be made out of metal (such as iron) or stone. Also, head contains a lot of dust and water ice. When comet comes closer to Sun it's surface warms and ice starts to melt. Due to low pressure in space it almost instantly evaporates creating water vapour. This vapour causes the particles of dust to raise above surface of head and to fall back of the head.
Tail is most viewed part of a comet. It best something that we can see with naked eye and that helps us to distinguish comet and all other celestial bodies. Tail is made out of two other tails. First is dust tail. It is created when dust particles rise from head of a comet and fall behing it. Gravity of a comet causes for these particles to follow head. Dust tail is always located opposite to direction of movement. Second tail is ionic tail. When solar particles (such as solar wind) hit comet they ionize atoms and molecules. This causes them to glow and produce light which we can see. Ionic tail is always opposite to direction in which Sun is located. When comet is far from Sun dust and ionic tail lay in same position. When comet is close to Sun dust and ionic tail not always lay in same position.
