The postulation that Allah (the name of God in Islam) historically originates as the moon deity Al-Lat (who was worshipped in pre-Islamic Arabia) originates in early 20th-century scholarship, most prominently advocated by American evangelicals from the 1990s. In mythology, a lunar deity is a god or goddess of the Moon, sometimes as a personification. These deities can have a variety of functions and traditions depending upon the culture, but they are often related. Some form of Moon worship can be found in most ancient religions.

Three importance of classification are: 

1. It helps in the identification of living organisms as well as in understanding the diversity of living organisms. 
2. To understand and study the features, similarities and differences between different living organisms and how they are grouped under different categories. 
3. It is essential to understand the inter-relationships among the different groups of organisms. 

In algebraic geometry, a nodal surface is a surface in projective space whose only singularities are nodes. A major problem about them is to find the maximum number of nodes of a nodal surface of given degree.

Conservation Laws: A conservation law is a hypothesis based on observation and experiments which cannot be proved. These can be verified via experiments.

Law of conservation of Energy: According to the general Law of conservation of energy, the energies remain constant over time and
convert from one form to another.

The law of conservation of energy applies to the whole universe and it is believed that the total energy of the universe remains unchanged.

Under identical conditions, the nature produces symmetric results at different time.

In the quantum of electromagnetism, Planck’s constant is the physical constant that relates the energy carried by a single photon to its corresponding frequency. Represented by h and measure using J.s in SI system and eV.s in the MKS system.

Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field.

The art objects such as paintings which were mostly found in india ajanta caves tell us about the life of buddha and and they were mostly placed to decorate the homes of the rich but in indus valley civilization the paintings were as an indentification on their currencies on which some animal burials or fossils were used

Rabi crops are known as winter crops. They are grown in October or November. The crops are then harvested in spring. These crops require frequent irrigation because these are grown in dry areas. Wheat, gram, barley are some of the rabi crops grown in India.

Examples of Rabi Crops

Following are some of the examples of rabi crops:

• Wheat
• Barley
• Oats
• Pulses
• Mustard
• Linseed

Synthetic industry : In this industry, two or more materials are mixed together to create a new product. For example, producing soap, biscuits, etc.

According to Boyle’s Law P₁ V₁ = P₂ V₂

Here the temperature is constant. Therefore

1.2 X 120 = P₂ X 180

OR

P₂ = 1.2 X 120 /180 = 0.8 bar

Therefore, the pressure would be 0.8 bar.
