The amount of C-14 at time t is
where
N₀ = inital amount of C-14
t = years
K = 0.0001 = 10⁻⁴
When the skull was discovered, the amount of C-14 contained 43% of N₀.
Therefore
Answer:
The age of the skull s 8440 years (nearest integer)

Answer:
Force, F = −229.72 N
Explanation:
Given that,
First charge particle,
Second charged particle,
Distance between charges, d = 0.0359 m
The electric force between the two charged particles is given by :
F = −229.72 N
So, the magnitude of force that one particle exerts on the other is 229.72 N. Hence, this is the required solution.
