The rate at which radioactive decay occurs & how much radioactive decay has occurred
AleksAgata [21]3 years ago
4 0

Answer:   How much radioactive decay has occurred

Explanation:  Radiometric dating is the source to determine the absolute age and time of the rocks.

Because the radioactive isotopes are unstable, They break down into several fragments over the time until they become a stable isotope.

Thus in order to accurately determine the absolute time, one should must know how much radioactive decay has occurred .

The actual density of pennies made before 1982 is about 8.8 g/mL. The actual density of pennies made after 1982 is about 7.2 g/m
trasher [3.6K]

To obtain more accurate values of the densities of the pennies:

  • more trials can be conducted to reduces the effect of measurement errors
  • more care should be taken in taken volume measurements by displacement of water to avoid splashing of water.

<h3>What is density of a substance?</h3>

The density of a substance is the ratio of the mass of the substance to the volume of that substance.

It is a measure of the compactness of the matter in a substance.

The densities of the pennies made before 1982 was 8.7 g/ml

The actual density of pennies made before 1982 is about 8.8 g/mL.

The densities of the pennies made after 1982 was 6.9 g/ml

The actual density of pennies made after 1982 is about 7.2 g/mL.

Due to several random and experimental errors, the values obtained from the experiment are not exactly the same with the accepted values.

To obtain more accurate values:

  • more trials can be conducted to reduces the effect of measurement errors
  • more care should be taken in taken volume measurements by displacement of water to avoid splashing of water.

In conclusion, the densities varied as as a result of random and experimental errors.
