Use the Gizmo to estimate the age of each of the objects below For these questions, each second in the Gizmo represents 1,000 years.
Using the Half-life Gizmo, estimate the ages of the objects as follows:
Egyptian papyrus: Approximately 12,000 years
Aboriginal charcoal: Approximately 24,000 years
Mayan headdress: Approximately 6,000 years
Neanderthal skull: Approximately 36,000 years.
1. Egyptian papyrus (63% original Carbon-14 atoms):
The papyrus has undergone decay, and given its remaining Carbon-14 percentage, it can be estimated to be approximately 12,000 years old. This calculation is based on the principle that each half-life represents a reduction to half the initial amount of radioactive material.
2. Aboriginal charcoal (22% original Carbon-14 atoms):
With a lower remaining percentage, the Aboriginal charcoal is estimated to be older than the papyrus. The calculation suggests an approximate age of 24,000 years, indicating a longer time since the initial presence of Carbon-14.
3. Mayan headdress (79% original Carbon-14 atoms):
The higher remaining percentage of Carbon-14 in the Mayan headdress indicates a more recent age compared to the previous objects. The estimation using the half-life concept suggests an age of around 6,000 years.
4. Neanderthal skull (3% original Carbon-14 atoms):
The Neanderthal skull has experienced significant decay, and the low remaining percentage implies a much older age. The estimation using the Half-life Gizmo suggests an approximate age of 36,000 years.

yes i thank..
Explanation:
i hope this helps
The given statement is False.
Renewable resources are the resources that are not synthesized by the human beings and are present naturally in the environment.
They are present in nature for free and can be used to obtain energy.
These are wind, solar energy, water, et cetera.
They are renewed again and again.
