Because Asia is a developing country so to earn money they ship things they make to more developed countries
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!!!
The correct answer is - II and III.
The agribusiness has been helping a lot to the people in the developing countries around the world, mostly with better food supply and the support in the traditional agricultural practices.
The better food supply comes from the proper distribution of the food on the home markets, and it is also food that is produced in the country, not imported one, so everyone sees the benefit from it.
The support in the traditional agricultural practices is also very important, as the farmers are managing to get easy access to the things they need for farming, but also they have secured market for their products. The traditional agricultural practices are also supported as in those ways it is possible to produce organic food, for which there's an ever growing market.
Western europe is best known for being the beginning of Western civilization.
