Calculate the amount, in grams, of an original 300-gram sample of radioactive isotope Potassium-40 remaining after
Aleksandr [31]

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 (m (t)), in grams, is described below:

m(t) = m_{o}\cdot e^{-\frac{t}{\tau} } (1)

Where:

m_{o} - Initial mass, in grams.

t - Time, in years.

\tau - Time constant, in years.

The time constant can be found from half life (t_{1/2}), in years, described in statement:

\tau = \frac{t_{1/2}}{\ln 2} (2)

If we know that m_{o} = 300\,g, t = 3.9\times 10^{9}\,yr and t_{1/2} = 1.3\times 10^{9}\,yr, then the current amount of the sample is:

\tau = \frac{1.3\times 10^{9}\,yr}{\ln 2}

\tau \approx 1.876\times 10^{9}\,yr

m = (300\,g)\cdot e^{-\frac{3.9\times 10^{9}\,yr}{1.876\times 10^{9}\,yr} }

m\approx  37.521\,g

The current amount of the Potassium-40 sample is approximately 37.521 grams.

Index fossils can provide information on the environment at the time they were deposited. True False
Anettt [7]

Answer: True

Explanation:

The index fossil are the fossils that are of animals and plants that remained preserved in the rock of the earth. It describes the particular span of the geological time or the environment. An index fossil can be easily recognized, is widely distributed and abundant.

The index fossil is the basis for defining the boundaries of the geological time scale with the correlation of the strata.

Those organisms which exhibited the short vertical range that is the life span on earth and the wide lateral range that is geographic distribution can be included as index fossil.

These fossils are indicative of the environment in which the organism used to live.
