50 points check your math before you post or i will report and take back the points an archaeologist in turkey discovers a spear head that contains 53% of its original amount of c-14

The spear is 4620 years old.

N=N0e^-kt  

N0 = initial amount of C-14 (at time t = 0)  

N = amount of C-14 at time t  

t = time, in years  

k = 0.0001

N/N0 = e^-kt  

we know N/N0 is 0.63  

so we have:  

0.63 = e^-kt  

we can take the ln of both sides, leaving us with:  

ln0.63 = -kt  

t = ln0.63 / -(0.0001)  

t = 4620 years  

hope this helps with your thing!

Explanation:

you got it mixed up with 63% for your question.

c

explanation:

idk

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
