Silicon carbide is used in Cutting very hard substances.

The given expression can be simplified as

6 ÷ 2 (1 + 2)

The expression can be simplified further by the order of operations, using BODMAS rule.

First evaluate Parentheses/Brackets, then evaluate Exponents/Orders, then evaluate Multiplication-Division, and finally evaluate Addition-Subtraction.

Now, the expression becomes 6 ÷ 2 (3)

According to the order of operations, division and multiplication have the same precedence, so the correct order is to evaluate from left to right. First take 6 and divide it by 2, and then multiply by 3.

6 ÷ 2 × 3

= 3 × 3

= 9

But not  6÷2×3 = 6 ÷ 6 = 1

Hence, 6 ÷ 2 (1 + 2) = 9.

When a running car stops suddenly, the passengers tends to lean forward because of Inertia of motion.

The minimum amount of energy required for a particular reactants to convert into products and is called as Activation Energy.

This activation complex is also termed as Transition State because according to Transition State Theory at transition state the existing bonds tend to increase in length and become weaken while, the new forming bonds tend to decrease in length and start becoming stronger.

Hence, the activated complex is in transition between reactants and products.

There are two types of sociological theories:

1. Macro and

2. Micro.

Macro theories focus on the society as a whole and aim at establishing the general characteristics of the society. It is basically looking at the society as a whole and looking at a bigger picture. It aims to answer three basic questions:

1) What holds the societies together?

2) What are the sources of conflict in a society?

3) How do societies change?

There are two branches of macro-sociological theories: consensus and conflict, with the main representative being functionalist and marxist respectively.

Micro theories on the other hand, focus on the individuals who make up the society unlike macro theory which looks at the society as a whole. Micro theories are small scale. Consider it a magnifying glass, when you look through it, you 'zoom' in to the society and see the individuals who have made up that particular society.

Symbolic interactionism is the sociological perspective which is most closely linked to microsociology.
