Question

WILL GIVE FAN AND MEDAL IF IT'S RIGHT.
What knowledge is radiometric dating based upon?
A. the rate of decay for certain isotopes
B. the name of the rocks
C. the weight of the samples
D. the sequence of layers in the rocks

Answer 1

the radioactive decay law is based on the decay constant, which varies in based the radioactive sample. Usually de decay constant is indicated by the symbol \[\lambda \]

Answer 2

so a?

Answer 3

Yes, I think

Answer 4

you are right!

Answer 5

THANK YOU

Answer 6

the radioactive law is:
\[N(t)=N _{0}*e ^{-\lambda t}\]
where N(t) is the number of atoms which are disintegrating, t is time, N_0 is the number of atoms at time t=0, namely the initial time

Answer 7

Thank you!
