Answer : The age of the artifact is,
Explanation :
Half-life = 5715 years
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the time taken to decay.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = time taken by sample = ?
a = initial activity of the reactant = 58.2 counts per minute
a - x = activity left after decay process = 42.8 counts per minute
Now put all the given values in above equation, we get
Therefore, the age of the artifact is,
These metals are silver and soft, much like the alkali metals of Group 1. These metals also react with water, though not as vigorously. Beryllium, interestingly, does not react with water. Each alkaline earth metal has two valence electrons.
Hope this helps :)
Technically speaking, yes you can. Using a microscope though.
The answer is A because The fact of temperature on volume changes of substance.
