After reviewing the graph you have given with the question, there are several reasons why carbon 14 can't be used to accurately determine the age of organic remains that are 1 million years old.
A few of the reasons are; Carbon-14 has a short half life, after 1,000,000 years there wouldn't be enough carbon 14, and too little of the original radioactive sample would remain. Any of these choices are correct for the answer to the question you asked.
Answer:
Five professional are Cartographer, Town planner, Teachers, Gis experts, Demographers,
Explanation:
- As cartography is the art and science of making maps the Cartographers use geographic data on maps from various maps, diagrams and define locational boundaries. Use the geographic principles of the globe to form models of the earth's surface.
- Town planners or urban geographers use the art of geography to interpret and plan the cities formation and development, they also use the basic geographic techniques like zoning and land-use patterns of a city, the internal structure, etc.
- Teachers, they use their knowledge of geography to teach and develop approaches so as the student can understand the world better, they use innovative ideas and out of text information to spread this body of knowledge far and wide.
- Demographers, generally study the population parameters based on the statistics and data collected from the surveys both primary and secondary. Population studies also come under this field, and analysis the population age and sex ratio, etc.
- Gis experts or professional working with the software need to have a thorough knowledge of geography as it helps them to formalise and plan various types of maps the as they are governed by the government bodies and private groups in the country.
The Moons rotation is precisely equal to it’s period of revolution.
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.
