Answer:
Option C. 2 half lives.
Explanation:
The following data were obtained from the question:
Original amount (N₀) = 1000 atoms
Amount remaining (N) = 250 atoms
Number of half-lives (n) =?
Half-life is defined as the time taken for the substance to reduce to half its original side. Mathematically, it can be obtained as follow:
N = 1/2ⁿ × N₀
N is the amount remaining.
n is the number of half-lives.
N₀ is the original amount.
Using the above formula, we can obtain the number of half-lives as follow:
Original amount (N₀) = 1000 atoms
Amount remaining (N) = 250 atoms
Number of half-lives (n) =?
N = 1/2ⁿ × N₀
250 = 1/2ⁿ × 1000
Cross multiply
250 × 2ⁿ = 1000
Divide both side by 250
2ⁿ = 1000/250
2ⁿ = 4
Express 4 in index form
2ⁿ = 2²
n = 2
Therefore, it will take two (2) half lives for the amount to get to 250 atoms.
Answer:
The five process bu which rocks can change from one form to another are -
1. Weathering 2. Metamorphism 3. Cooling and crystallization 4. Lithification of sediments 5. Igneous rocks change into metamorphic rocks
Explanation:
The processes by which rocks can change from one form to another are as follows :
1. Weathering : It wears/breaks down the rocks at the surface of Earth’s into smaller pieces.
2. Metamorphism : This changes the entire texture as well as the mineral composition of the rock under conditions of extremely high temperature and pressure.
3. Cooling and crystallization from a molten magma material results in the generation of igneous rocks.
4. Lithification of sediments with proper compaction and cementation leads to the formation of consolidated sedimentary rocks.
5. Igneous rocks change into metamorphic rocks when subjected to high temperature and pressure conditions deep inside the Earth.
