Answer:
See solution and explanation below
Explanation:
a) From;
N/No = (1/2)^t/t1/2
1/8 = (1/2)^t/1.25 * 10^9
(1/2)^3 = (1/2)^t/1.25 * 10^9
3 = t/1.25 * 10^9
t = 3 * 1.25 * 10^9
t = 3.75 * 10^9 years
b)
N/No = (1/2)^40,110/5,730
N/No = (1/2)^7
N/No = 1/128
percentage remaining after 40,110 years = 1/128 * 100 = 0.78%
c) N/200 * 10^-9 = (1/2)^4.26 * 10^9/0.710 * 10^9
N/200 * 10^-9 = (1/2)^6
N/200 * 10^-9 = 1/64
64 N = 200 * 10^-9
N= 3.125 * 10^-9 g
d) Radiocarbon dating can not be used to determine the age of the solar system since the solar system is as old as the universe and was formed billions of years ago. Radiocarbon dating can only be accurately used to obtain the age of objects of plant or animal origin between 1000 - 10000 years old.
Well first you needed to find gold and then they needed to find land works
<span>When new clay sediment is deposited on top of old beach material, it's known as.C. transgression.This is because the clay would have to come from sea inundating the beach ie rising and depositing the clay on the old beach. The sea rising could be from say tectonic movement or from glaciers melting but before glacial rebound.</span>
True it is in a particular time in the past
