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
Where, k is rate constant
So,
The rate constant, k = 5.5452 × 10⁻¹⁰ years⁻¹
Initial amount [A₀] = 80 micrograms
Final amount = 10 micrograms
Using integrated rate law for first order kinetics as:
So,
So,
<u>The rock is 3.75 billion years ago.</u>
The third phase of the Keynesian LRAS Curve shows the economy at full employment. This means that the factors of production are being used at full capacity.
<h3>What do you mean by long-run aggregate supply?</h3>
