The correct method would be multiplying the speed of light by the time it takes to travel from the moon to Earth. This is because:
S=So+V*t
In which:
S= space
So= space at the start (origin)
V=speed or velocity
t=time
By multiplying miles/second by seconds you get miles as a result.
Since the half life of the radioactive isotope is 4,000 years, after 4,000 years the amount of the isotope would decrease by half. (Hence the name, half life.) So, after 4,000 years, there would be half of the isotope left in the fossil.
Answer:
This is because the proportion of light that gets absorbed is affected by the number of molecules that it interacts with. Solutions that are more concentrated have a larger number of molecules that interact with the light that enters, thus increasing its absorbance. ... This increases the absorbance.
