Conservation policies: Use of three Rs and CSR.
Answer:
The age of the rock = 2800.6 million years = 2.8 billion years.
A simple method of analysis similar to Carbon dating is used to obtain the required age of the rock. Radioactive substances decay according to first order reaction kinetics. So, plugging all the required parameters into the general equation for amount of substance left in a first order decay gives us the age of the rock.
Explanation:
Half life of Uranium-235 = 700 million years (from literature)
The decay of radioactive substances follow first order reaction kinetics.
The general equation is given as
A(t) = A₀ e⁻ᵏᵗ
A(t) = Amount of radioactive substance left after a particular time = 6.25%
A₀ = initial amount of radioactive substance = 100%
t = time that has passed since the beginning = age of the rock = ?
k = decay constant
The decay constant is related to the half life (T) through the relation,
k = (In 2)/T
k = (0.693/700) = 0.00099 /million years
A(t) = A₀ e⁻ᵏᵗ
6.25 = 100 e⁻ᵏᵗ
0.0625 = e⁻ᵏᵗ
In e⁻ᵏᵗ = In 0.0625 = -2.7726
-kt = - 2.7726
t = (2.7726/0.00099) = 2800.6 million years
t = 2.8 billion years.
Hope this Helps!!!

Explanation:
Answer:
9 more muffins
Explanation:
Lucinda has 9 ounces of flour.
To make a cupcake she requires 1/3 ounce of flour, therefore the number of cupcakes she can make from 9 ounces of flour can be given by:
(1/3)x = 9 where x is the number of cupcakes.
Therefore, x = 9 × 3 = 27 cupcakes
To make a muffin she requires 1/4 ounce of flour, therefore the number of muffins she can make from 9 ounces of flour can be given by:
(1/4)y = 9 where y is the number of muffins.
Therefore, y = 9 × 4 = 36 muffins
The number of more muffins she can make more than cupcakes from her flour = 36 - 27 = 9 more muffins
Answer: Extreme heat and pressure from deep within Earth cause changes to the rocks appearance, structure, and composition.
Explanation:
Remember!
- Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles/sediments.
- Igneous rock is formed through the cooling and solidification of magma or lava
- Metamorphic rocks are changed by heat and pressure
