B.crust
C.inner core
D.mantle
The mantle is the layer of the Earth that contains most of the Earth's mass. The correct option is (D).
The part of the Earth's crust that contains the majority of its mass is called the mantle. Between the crust and the outer core, it is located. The mantle is made up of hot, flowing rock known as magma and is a thick, semi-solid layer. It makes up around 84% of the entire volume of the planet and is in charge of tectonic plate movement, volcanic activity, and other geological processes that sculpt the surface. In comparison to the mantle, the outer core and inner core have substantially smaller volumes.
Hence, the mantle is the layer of the Earth that contains most of the Earth's mass. The correct option is (D).

As per the modern classificationsystem, the class, order, genus, species is arranged from least specific to most specific one. The correct option is C.
The term classification can refer to one or more of the following: the process of classifying the resulting set of classes the classification of elements into predefined classes Classifying, in its broadestsense, is a fundamental concept and a component of almost all activities.
In 1956, Herbert FaulknerCopeland (1902-1968) proposed the four kingdom classification.
Monera, Protista, Plantae, and Animalia were the four kingdoms. He classified unicellular organisms into two groups: the Monera kingdom and the Protista kingdom.
The classificationsystem provides a wealth of information about organism characteristics. Using scientific names as a shorthand method of describing a plant or animal can thus be beneficial.
Thus, the correct option is C.

D) phylum, order, species, family
Answer: 3m/s^2
Explanation:
Given that:
Acceleration of object = ?
Force = 9 N
Mass of object = 3 kg
Since force is the product of the mass of an object and the acceleration by which it moves i.e Force = mass x acceleration
9N = 3kg x acceleration
Acceleration = 9N/3kg
Acceleration = 3m/s^2 (3 metres per second square)
Thus, an acceleration of 3m/s^2 is produced.
Voltage difference causes charge to flow from higher potential to that of a lower potential.
This is also known as Voltage difference and it is the difference in electric potential between two points.
V= W/Q
where v is potential difference, w is work done and q is charges.
This allows for charges to flow from higher potential to that of a lower potential.

Answer:
Voltage difference causes charge to flow from higher potential to that of a lower potential.
Explanation:
Voltage Difference:
It is work done per unit charge in moving a charge from one point to another point.
V = Voltage difference
W = Work done
Q = Charge
Then,
unit : Volt or Joule/Coulomb
Flow of charge :
A free positive charge move from a region of higher potential to that of lower potential whereas a free negative charge moves from lower potential region to a higher potential.
Thus, a voltage difference is required for the flow of charge.
Direction of conventional current is from positive terminal to negative terminal.
Direction of electron is from negative to positive.
