Answer:
2.62 years
Explanation:
The half life of a material is the time taken for half of the number of radioactive atoms in a radioactive material to remain.
If a radioactive material is cut into pieces, each piece has the same half life as the whole material.
Hence, if Strontium-147 is cut into pieces, each piece will have a half life of 2.62 years, just as the whole material.
Answer: с Polysaccharides, monosaccharides
Explanation:
The correct answer is - D. It is impossible to dig through the ice on Antarctica.
Even though the technology is much more advanced nowadays than in the past, the extraction of the numerous natural resources from Antarctica is still pretty much impossible because of the ice cover over the continent.
On average, the ice is around 2 km thick on top of the landmass. Considering the fact that in order to get to the resources, the people will have to dig even more into the ground after they manage to break through the ice, makes it almost impossible, and not to mention economically unjustifiable.

- makes the country more wealthy and improves the living conditions of the people. In many cases, this is used for military advancement, scientific advancement, and technological advancement
Explanation:
Answer:
15003.19
Explanation:
The fossil bones age can calculated by using the formula
t = (In ( 12.5 /100) / (-λ)) × half life
where λ = 0.693
t = ((In (12.5 /100) / (-0.693) ) × 5000 = 15003.19 years
the age of the fossil bones is 15003.19
thus the age of the human habitation site 15003.19
