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
Answer: Cognitive
Explanation:
Cognitive psychology focuses on the mind and the processes involved therein. It focuses therefore on mental processes which include but are not limited to, attention, memory, thought process and creativity.
