Answer:
the cloth is old by 1,844 years
Explanation:
The computation is shown below:
The half-life of C^(14) is 5730 years
Now
=1.210 × 10^-4 years^(-1)
Now
= .000121,
so t = 1844 yrs
hence, the cloth is old by 1,844 years
Angle at which under water diver sees the sun from horizontal =
Angle from normal direction = 90 - 57 =
Refractive index of water = 1.33
Refractive index of water = 1
We have the equation
1.33 * sin = 1 *sin
=
This angle is angle from normal, so angle seen by fisherman from horizontal = 90 - 46.42 =
