Answer:
The current amount of the Potassium-40 sample is approximately 37.521 grams.
Explanation:
The amount of the sample of the radioactive isotope decays exponentially in time, the amount of mass of the sample as a function of time (
), in grams, is described below:
(1)
Where:
- Initial mass, in grams.
- Time, in years.
- Time constant, in years.
The time constant can be found from half life (
), in years, described in statement:
(2)
If we know that 
, 
and 
, then the current amount of the sample is:
The current amount of the Potassium-40 sample is approximately 37.521 grams.
Lithosphere is the crust and upper mantle of the earth.
Climate change,Deforestation,<span>Pollution</span>
It was divided because of the tensons between the allies and soviets
It causes for the world climate to rise causing global warming. Also erosion causes be buildings to be eaten away from water or acid rain and can destroy homes and possible hurt humans. Deposition runs into the water and streams with eventually goes to the water lines to the food and drinks we consume today.
