Answer:
<u>True. cover 71% of the entire earth</u>.
Explanation:
- The oceanic mass found ver the earth is well-known mass reserves of 97.3% of all waters in the world. Most Of it exists in salty forms and rest 3% is in the form of lakes and glaciated bodies as the next big reservoirs.
- They are also considered as the carbon sinks, constantly absorbing the carbon dioxide gas, the Atlantic Ocean covers an area of 82.4 km square with a volume of 323.6, followed by the Pacific Ocean, with 165.2 km area and a volume of 707.6, and the Indian Ocean has an area of 73.4 km and volume of 291.0 km cube.
- Variability is an important component of the oceanic water there is also water in the earth's mantle and is available at a temperature of 1,100 degrees celsius.
A. Plea bargain
Explanation:
Plea bargain is one of the common strategy used to reduce the court's caseload and reduce cost of trials.
This process involves an agreement between the prosecution and defendant where the defendant agrees to plead guilty in order to receive some pardon or reduced sentence.
Plea bargain helps fast-track the legislative process helps to reduce cost on prolonged trails.

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.
