Answer:
The organism died 35900 years ago
Explanation:
- Half life C-14 is 5730 years.
- For decay of radioactive nuclides:
is the fraction of radioactive nuclide remain present after t time and
is the half-life of radioactive nuclide
- Here
Plug-in all the values in the above equation:
So, t = 35900 years
Hence the organism died 35900 years ago
Answer:
neap tide
Explanation:
There are two different types of tides, which are the spring tide and the neap tide.
Neap tides are weak tides which occur when the gravitational forces of the sun and the moon are at right angles to each other with respect to the earth. Since the sun and moon are at right angles, it causes a difference between the low and high tide.
The spring tide are strong tides which occur when the moon, sun and earth are in straight line. The spring tide occur during full moon and new moon.
