Answer:
In 2003 the Federal Republic of Yugoslavia was renamed to State Union of Serbia and Montenegro. The union peacefully broke up when Serbia and Montenegro became independent states in 2006, while Kosovo proclaimed its independence from Serbia in 2008.

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.

The maximum amount of electricity that on-shore wind farms can produce is 200 kWh/d per person under ideal conditions i.e. covering the entire nation in wind turbines.
The following steps are taken in the energy conversion process while producing electricity from wind turbines:
First, the wind strikes the turbine blades and transfers its kinetic energy to them. A generator is attached to the turbine blades. The generator shaft is turned by the kinetic energy of the turbine blades.
The generator then produces electricity out of the kinetic energy of the blades.

South asia can be divided into three basic kinds: tropical, dry, and temperate. the Northeast East from tropical to subtropical temperature moving West to moisture and the elevation change causing a steppe and a desert climate that is like the Middle East.
