It was marked by the down fall of rich elite class and emergence of socialist democracy and socialist political civilization
Now there will be dominant state-owned enterprises sector along with the market capitalism and private ownership
hence, option B is correct
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!!!
Answer:
The two rock can be confused with each other as both appear rough to touch and both are found in shades of black & brown and dark themes, also shades of grey sometimes prevail.
They differ in the mode of formation as Quartzite is Metamorphic Rock while Basalt is the Igneous rock formed from the Volcanoes
Explanation:
The two rock can be confused with each other as both appear rough to touch and both are found in shades of black & brown and dark themes, also shades of grey sometimes prevail. They do have similarities in the hardness on some scale as Quartzite is hard while basalt is intermediate in hardness.
Major difference between them are:
They differ in the mode of formation as Quartzite is Metamorphic Rock while Basalt is the Igneous rock formed from the Volcanoes. Quartzite have medium grain size and foliated, granular structure while Basalt is fine grained and glassy in texture.
Answer:
First Nations have lost approximately 98% of their land and were forced to live in isolated reserves. ... Many First Nations people died due to European diseases such as smallpox. European colonization destroyed their way of life and caused anger and resentment that still exists today.
Explanation:
it basically destroyed them... they stole everything they had...
D. none of the above i only commented for the points
