Suppose you find a rock that contains 10 micrograms of radioactive potassium-40, which has a half-life of 1.25 billion years. By

attashe74 [19]

Answer:

The rock is 3.75 billion years ago.

Explanation:

Given that:

Half life = 1.25 billion years

1 billion years = 10⁹ years

So,

Half life = 1.25 × 10⁹ years

$t_{1/2}=\frac {ln\ 2}{k}$

Where, k is rate constant

So,

$k=\frac {ln\ 2}{t_{1/2}}$

$k=\frac {ln\ 2}{1.25\times 10^9}\ year^{-1}$

The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹

Initial amount [A₀] = 80 micrograms

Final amount $[A_t]$ = 10 micrograms

Using integrated rate law for first order kinetics as:

$[A_t]=[A_0]e^{-kt}$

So,

$10=80\times e^{-5.5452\times 10^{-10}\times t}$

$80e^{-5.5452\times \:10^{-10}x}=10$

$\frac{80e^{-5.5452\times \:10^{-10}x}}{80}=\frac{10}{80}$

$\ln \left(e^{-5.5452\times \:10^{-10}x}\right)=\ln \left(\frac{1}{8}\right)$

$x=\frac{10^{10}\times \:3\ln \left(2\right)}{5.5452}=3.75\times 10^9$

So,

The rock is 3.75 billion years ago.

Dima020 [189]

I believe the correct answer from the choices listed above is option 2. The Kansas Nebraska act continued ideas of compromise of 1850. The bill was reported to the main body of the Senate on January 4, 1854. The bill had been modified by Douglas, who had also authored the New Mexico Territory and Utah Territory acts, to mirror the language from the Compromise of 1850.

Ryan is hooked up to an electroencephalograph (eeg) in a sleep lab. As the researcher watches the printout from the eeg, sleep s

Rasek [7]

Based on this information, the researcher can conclude that Ryan "has just entered Stage 2 sleep".

Stage 2 sleep, which for the most part keeps going around 20 minutes, is described by an abating pulse and a reduction in body temperature. Your body lessens its action to set you up to go into a profound rest.

It winds up harder to wake you up.

Your brain begins to produce bigger waves.

Your circulatory strain likewise diminishes, and other metabolic capacities back off as well.
