PLEASE HELP :) THANK YOU Geologic processes change Earth's surface on varying scales of space and time. They range from rapid to
very slow; from large to microscopic.
How does the time scale of slow geologic processes affect human perception of landforms on Earth? Provide details to support your answer.

The mass of the Potassium-40 is
2
The Dose per year in Sieverts is
Explanation:
From the question we are told that
The isotopes of potassium in the body are Potassium-39, Potassium-40, and Potassium- 41
Their abundance is 93.26%, 0.012% and 6.728%
The mass of potassium contained in human body is per kg of the body
The mass of the first body is
Now the mass of potassium in this body is mathematically evaluated as
substituting value
The amount of Potassium-40 present is mathematically evaluated as
0.012% * 0.024
The dose of energy absorbed per year is mathematically represented as
Where E is the energy absorbed which is given as
Substituting value
The Dose in Sieverts is evaluated as
