Nitrogen is found in a diatomic form with a triple bond between two atoms. N2 molecules are held together by weak van der Waal's force of attraction which can be easily broken by the collision of the molecules. So, N2 is a gas at room temperature.

Joule is the unit for energy
Dimension Formula for Joule is [M¹L²T⁻²]
Let n1(joule)=n2(erg)
n1(M₁¹L₁²T₁⁻²]=n2[M₂¹L₂²T₂⁻²]
n2=n1(M₁¹L₁²T₁⁻²] /M₂¹L₂²T₂⁻²]
=n1x(M1/M2)¹x(L1/L2)²x(T1/T2)⁻²
=1x(1kg/gm)¹x(1m/1cm)²x(1s/1s)⁻²
=1x(1000g/gm)x(100cm/1cm)²x(1s/1s)⁻²
=10⁷
Therefore n1(joule)=n2(erg)
∴1 Joule=10⁷erg

Principle of Homogeneity states that dimensions of each of the terms of a dimensional equation on both sides should be the same. This principle is helpful because it helps us convert the units from one form to another

Characteristics of Civilization
All civilizations have certain characteristics. These include:
(1) large population centers
(2) monumental architecture and unique art styles
(3) shared communication strategies
(4) systems for administering territories
(5) a complex division of labor
(6) the division of people into social and economic classes.
Urban Areas
Large population centers, or urban areas (1), allow civilizations to develop, although people who live outside these urban centers are still part of that region’s civilization. Rural residents of civilizations may include farmers, fishers, and traders, who regularly sell their goods and services to urban residents.

Body wave -
A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface. P and S waves are body waves. Each type of wave shakes the ground in different ways...
Surface wave -
seismic wave that travels across the surface of the Earth as opposed to through it. Surface waves usually have larger amplitudes and longer wavelengths than body waves, and they travel more slowly than body waves do. Love waves and Rayleigh waves are kinds of surface waves.
