Answer:
The age of the bones is approximately 14172 years.
Explanation:
The age of the bones can be determinated using the following decay equation:
(1)
<u>Where:</u>
N(t): is the quantity of C-14 at time t
No: is the initial quantity of C-14
λ: is the decay rate
t: is the time
First, we need to find λ:

<u>Where:</u>
t(1/2): is the half-life of C-14 = 5730 y
Now, we can calculate the age of the bones by solving equation (1) for t:
We know that the bones have lost 82% of the C-14 they originally contained, so:

Therefore, the age of the bones is approximately 14172 years.

Rapid eye maneuver
Explanation:
during slumber, your eyes move quickly on different directions.
Answer:
14.27 mm
Explanation:
Force = 80 Newton
Pressure exerted = 5 bar = 5×10⁵ Pa
Pressure exerted = Force/Area
Area = Force/Pressure

Area of the cylinder=πd²/4

Hence diameter of cylinder 14.27 mm
