Answer:
The correct answer would be = t = 2.112 billion years
Explanation:
Given:
The number of crystal of uranium = 275 billion
The number of crystal of lead = 1925 billion
The half-life for 235U = 704 million years
Formula using :
N = N0e−λt
where,
no. of daughter atoms = N
at time t= 0, No. of parent atoms = N0.
Time = T
Half life = 0.693/λ
Decay constant = λ
Solution:
by putting value in the formula of the half-life
λ = 0.693/0.704
λ = 0.9844
Now, putting value in the formula for the age of granite.
275 = (275+1925)e^-0.9844 t
1/8= e^-0.9844 t
e^0.9844 t = 8
taking log
0.9844t = 2.07944
t = 2.112 billion years
Function. The capsule is considered a virulence factor because it enhances the ability of bacteria to cause disease (e.g. prevents phagocytosis). The capsule can protect cells from engulfment by eukaryotic cells, such as macrophages. ... Capsules also contain water which protects the bacteria against desiccation.
