1. Gravitational Force: It is the force of mutual attraction between any two objects by virtue of their masses. It is a universal force as every object experiences this force due to every other object in the universe.
2. Electromagnetic Force: It is the force between charged particles. Charges at rest have electric attraction (between unlike charges) and repulsion (between like charges). Charges in motion produce magnetic force. Together they are called Electromagnetic Force.

Factors of production (labour and capital) are always jointly used: Labour is combined with capital (say plant, machinery etc). In India, there is severe shortage of capital. In the absence of capital, labour cannot be used. Hence, there is huge unemployment of labour although scarcity of resources is a universal fact.

Organic chemistry is a branch of chemistry that studies the structure, properties and reactions of organic compounds, which contain carbon in covalent bonding. Study of structure determines their chemical composition and formula.

The federal bureaucracy performs three primary tasks in government: implementation, administration, and regulation. When Congress passes a law, it sets down guidelines to carry out the new policies. Actually putting these policies into practice is known as implementation. The bureaucracy provides necessary administrative functions, like conducting examinations, issuing permits and licenses, and collecting fees. Essentially, it handles the paperwork of everyday government operations.

A coalition government is a form of government in which political parties cooperate, reducing the dominance of any one party within that "coalition". The usual reason for this arrangement is that no party on its own can achieve a majority in the election. Legislative power is constitutionally vested in the Parliament of India of which the president is the head, to facilitate the lawmaking process per the constitution (Article 78, Article 86, etc.). The president summons both the houses (Lok Sabha and Rajya Sabha) of the parliament and prorogues them.

Society is a permanent organization. However, members of society are interdependent on each other for survival but it continues to exist even after the death of an individual. Society is dynamic, without change no society can survive long. Change may be slow or rapid. The Human and Social Dynamics funding instrument is a discipline-specific funding instrument which supports basic research in Social Science and the Humanities. ... The dynamics of human and social behavior. Social cohesion and identity. Societal change and the evolution of modern society.

SAMPLE SURVEYS
In a sample survey, only part of the total population is approached for information on the topic under study. These data are then 'expanded' or 'weighted' to make inferences about the whole population. We define the sample as the set of observations taken from the population for the purpose of obtaining information about the population.

Advantages of Sample Surveys compared with Censuses:

• Reduces cost - both in monetary terms and staffing requirements.
• Reduces time needed to collect and process the data and produce results as it requires a smaller scale of operation.
• (Because of the above reasons) enables more detailed questions to be asked.
• Enables characteristics to be tested which could not otherwise be assessed. An example is life span of light bulbs, strength of spring, etc. To test all light bulbs of a particular brand is not possible as the test needs to destroy the product so only a sample of bulbs can be tested.
• Importantly, surveys lead to less respondent burden, as fewer people are needed to provide the required data.
• Results can be made available quickly.

A computer consists of five functionally independent main parts input, memory, arithmetic logic unit (ALU), output and control unit. Input device accepts the coded information as source program i.e. high level language. A computer has four main components: the central processing unit or CPU, the primary memory, input units and output units. Every computer system has the following three basic components: Input unit. Central processing unit. Output unit.
