There should be a sufficient amount of the selected isotope in the rock.
The half-life of the isotope must be long enough to capture the age of the rock.
Explanation:
Sully must consider two main aspect before selecting her choice isotope for dating.
There must be sufficient amount of the selected isotope in the rock.
The half - life of the isotope must be long enough to capture the age of the rock.
- Radiometric dating gives a rock an absolute numerical age.
- The half-life of an isotope is time take for half of a radioactive element to decay.
- If the half-life of an isotope is very short, all the parent nuclide would have turned to daughter nuclides.
- Also, we must have sufficient amount of both the daughter and parent isotope in the selected rock.

Explanation:
Toothpaste is an abrasive that contains many things, but mainly phosphates.
Answer:
6.1 cm³
Explanation:
To solve this problem we first need to keep in mind <em>Archimedes' principle</em>:
- The volume of water (or any fluid) displaced by a submerged object is equal to the object's volume.
With that in mind we <u>calculate the volume of the granite piece in mililiters</u>:
- Volume displaced = 47.6 mL - 41.5 mL = 6.1 mL
- Volume of the granite piece = 6.1 mL
Given that one cubic centimeter is equal to one mililiter, the volume of the granite piece in cm³ is 6.1 cm³.
