The answer is below
Explanation:
1) Equator: The equator is an imaginary line that divides the earth into two equal parts known as the northern hemisphere and southern hemisphere. The equator is a line of latitude.
Line A is the equator
2) Latitude: Latitude are imaginary lines on earth that run from the east to west.
Line B are lines of latitude
3) Longitude: Longitude are imaginary lines on earth that run from the north to south.
Line F is a line of longitude
4) Prime Meridian: The prime meridian is a 0° line of longitude. It serves as a reference for other lines of longitude measurement.
Line E is a prime meridian.
5) South pole: The south pole is at a latitude of 90°S and all the lines of longitude meet there.
Point D is the south pole
6) North pole: The north pole is at a latitude of 90°N and all the lines of longitude meet there.
Point C is the south pole
Answer:
50 atoms have decayed during that time
Explanation:
The radioactive decay is represented as
Where N is the amount of radioactive element after a certain time period
N0 is the amount of radioactive element during the initial time period
X is the half life of the radioactive element
Substituting the given values in above equation, we get:
atoms
So, 50 atoms of carbon-14 remain are left after decaying for 5700 years.
Hence, atoms of carbon-14 that decay during 5700 years are 100-50 - 50
