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.
A rock on Earth's surface tends to be weathered more because it is exposed to wind, precipitation, and the effects of gravity. A rock buried underground does not experience weathering from wind, precipitation, or gravity.
