Q1.In which among the following year was ‘liberalised industrial policy’ in India was announced for the first time?
Answer : Option CExplaination / Solution:
Liberalised Industrial Policy was introduced in 1991 in India. Because before that all the industries needed licensing and permission from government to commence their business, this resulted in depletion of Entrepreneurial spirit. Hence resulted in Backwardness of Indian Industry
Chemistry does not deal in explaining superconductivity.
*In superconducting materials the charecteristics of
superconductivity appear when the temperature is lowered below a
critical temperature.
*The onset of superconductivity is accompanied by abrupt changes in
physical properties which are more related to phase transitions of the
material .
These aspects of studies in properties of materials are better related to studies in the fields of Physics , eventhough principles involved in Chemistry & Physics go hand to hand.
Answer : Option DExplaination / Solution:
The theory for ideal gases makes the following assumptions
1. Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something—usually each other or the walls of their container.
2. Particles are point masses with no volume. The particles are so small compared to the space between them, that we do not consider their size in ideal gases.
3. No molecular forces are at work. This means that there is no attraction or repulsion between the particles.
4. Gas pressure is due to the molecules colliding with the walls of the container. All of these collisions are perfectly elastic, meaning that there is no change in energy of either the particles or the wall upon collision. No energy is lost or gained from collisions.
5. The time it takes to collide is negligible compared with the time between collisions.
6. The kinetic energy of a gas is a measure of its Kelvin temperature. Individual gas molecules have different speeds, but the temperature and kinetic energy of the gas refer to the average of these speeds.
7. The average kinetic energy of a gas particle is directly proportional to the temperature. An increase in temperature increases the speed in which the gas molecules move.
8. All gases at a given temperature have the same average kinetic energy.
9. Lighter gas molecules move faster than heavier molecules.
Q6.All the support structures which facilitates development of a country constitute its
Answer : Option BExplaination / Solution:
Infrastructure is the basic physical systems of a business or nation; transportation, communication, sewage, water and electric systems are all examples of infrastructure. They are vital to a country's economic development and prosperity.
Answer : Option DExplaination / Solution:
In Economics, goods are materials that satisfy human wants and provide utility. A good may be a consumable item that is useful to people but scarce in relation to its demand, so that human effort is required to obtain it.
Answer : Option AExplaination / Solution:
Dalton was developed the theory of the structure of matter and this theory is known as Dalton’s atomic theory. His research was based on experiments and also from law of chemical combination. Dalton’s atomic theory was quickly explained the many heretofore unexplained chemical phenomena. Dalton’s atomic theory quickly became the theoretical foundation in chemistry.
Dalton’s atomic theory stated that:
All the matter is made of atoms which are tiny particles and indivisible.
All the given atom of the element is identical in mass, size, shape, and in other properties.
All different elements have different types of atoms and also different in their mass, size, shape, and in other properties.
All the atom of an element cannot be made or destroyed.
Answer : Option BExplaination / Solution:
Biotic components include all living organisms present in an ecosystem. Competitors and predators are biotic components of habitat.
Answer : Option CExplaination / Solution: Zn2+ also serves as an activator of a group of enzymes: alcohol dehydrogenase, pyridine nucleotide dehydrogenase, carboxypeptidase.
