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:
![[A_t]=[A_0]e^{-kt}](https://tex.z-dn.net/?f=%5BA_t%5D%3D%5BA_0%5De%5E%7B-kt%7D)
So,





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

Answer:
The two countries with the closest land to the North Pole are Canada and Greenland (Kingdom of Denmark).
Explanation:
Geographers generally believe that the closest piece of land to the North Pole is Kaffeklubben Island, which is an island off the northern coast of Greenland. Kaffeklubben Island is located about 430 miles from the North Pole. There are some semi-permanent banks of rock and gravel that might technically be claimed to lie closer to the geographical point. The nearest permanent settlement is Alert in the Qikiqtaaluk Region of Nunavut, Canada. The permanent population there however is only 62. There are more people residing in Alert at any given time, but they are there temporarily because they man weather stations and other government and military posts in Alert. It is 508 miles from the North Pole. The North Pole is located in the center of the Arctic Ocean and it is covered with shifting pieces of ice.
