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,

<u>The rock is 3.75 billion years ago.</u>

Varian is finding it hard to learn Greek in his first year of college because he took Latin in his last two years of high school

posledela

Answer:

B) proactive interference

Explanation:

proactive interference is tendency of previous learning to interrupt current learning.

since here, varian's previous learning of Latin is making him difficult to grasp Greek. It can be well explained by proactive interference.

motivated forgetting happens when people try to forget certain things which they find irrelevant either unconsciously or consciously

proactive interference is phenomenon in which current learning hinders the learning of previous learnt knowledge.

temporary amnesia also known as transient amnesia is phenomenon in which a person losses memory before, during and after sometime of the event(the particular event which one is not able to remember).

Vika [28.1K]

Answer:

Transmitted

Explanation:

What is Cultural Transmission?

Cultural transmission is the ability to pass information on from one individual to another even across generations -- that makes us unique Learning can be done by observing what happens in the world around us, for example, by associating events that frequently occur together (or in a rapid sequence). However, human "communication" may constitute such a powerful instrument that it overrides "statistics", as observed in a study.

Cultural transmission is the one-directional way that information is given to us.
