  1. What do you understand by ‘people as a resource’? Answer: ‘People as a resource’ is a term that means how the population can be an asset and not a liability. It a way of referring to the working class of society in terms of their existing productive skills and abilities. The population becomes human capital when an investment is made in the form of education and training. Education and health also help human beings to be an asset to the economy. Thus, people as a resource refers to the working population that results in the development of society. 2. How is human resource different from other resources like land and physical Capital? Answer: Human resources are different from other resources like land and physical capital because human beings can use other resources to give out productive output. However, resources like land and physical capital are dependent on human resource for their use and cannot give any productive output all by themselves. 3. What is the role of educati...

 1.  Modern farming methods require more inputs which are manufactured in industries. Do you agree? Answer: Yes, it is correct to say that modern farming methods require more inputs which are manufactured in industries. It is because modern farming methods use high-yielding varieties of seeds. These seeds require both chemical fertilisers and pesticides, agricultural implementations like tractors and proper irrigation facilities like electric tube wells, and all these elements are manufactured in industries. However, on the other hand, traditional farming methods use a relatively low-yielding variety of seeds and use cow dung and other natural manures as fertiliser, which is why they are less dependent on industrial outputs. 2. How did the spread of electricity help farmers in Palampur? Answer: The spread of electricity helped the farmers of Palampur as it aided in the transformation of the irrigation system of the village. The farmers earlier used Persian wheels to draw water...

Answer. Jawahar Lal Nehru in his speech, ‘Tryst with Destiny’ used the expression, ‘not wholly or in full meas...

  Balanced and Unbalanced Forces When balanced forces are applied to an object, there will be no net effective force acting on the object. Balanced forces do not cause a change in motion. Unbalanced forces acting on an object change its speed and/or direction of motion. It moves in the direction of the force with the highest magnitude. Frictional Force The force that opposes relative motion is called friction. It arises between the surfaces in contact. Example: When we try to push a table and it does not move is because it is balanced by the frictional force. First Law of Motion A body continues to be in the state of rest or uniform motion in a straight line unless acted upon by an external unbalanced force. The First Law is also called the Law of Inertia. Inertia Basically, all objects have a tendency to resist the change in the state of motion or rest. This tendency is called inertia. All bodies do not have the same inertia. Inertia depends on the mass of a body. T...

  1. What is a tissue? Solution: A tissue is defined as a cluster of cells, which are similar in structure and work together to perform a particular function. 2. Name the types of simple tissues. Solution: The types of simple tissues are as follows: ➢ Parenchyma ➢ Collenchyma ➢ Sclerenchyma 3. What are the constituents of phloem? Solution: The phloem constitutes of the following four elements, they are: ➢ Sieve tube ➢ Companion cells ➢ Phloem parenchyma ➢ Phloem fibres 4.  Name the tissue responsible for movement of our body. Solution: Two tissues jointly are responsible for the movement of our body, namely: ➢ Muscular tissue ➢ Nervous tissue 5. What does a neuron look like? Solution: A neuron is a nerve cell consisting of the cell body with a nucleus and cytoplasm from which a long and thin hair-like structure emerges. Every neuron has one elongated part known as the axon, and several short and small branched structures known as dendrites. A single neuron can even be a meter ...

  1. Who discovered cells, and how? Solution: In 1665, Robert Hooke discovered cells while examining a thin slice of cork through a self-designed microscope. He observed that the cork resembled the structure of a honeycomb consisting of numerous tiny compartments. The minuscule boxes are referred to as cells. 2. Why is the cell called the structural and functional unit of life? Solution: Cells form the structure of an entity. A group of cells form a tissue, further an organ and ultimately an organ system. They perform fundamental functions and life processes such as respiration, digestion, excretion etc., in both unicellular and multicellular entities. They perform all the activities independently. Hence, cells are referred to as structural and fundamental units of life. 3. Why is the plasma membrane called a selectively permeable membrane? Solution: The plasma membrane is called as a selectively permeable membrane as it permits the movement of only certain molecules in and out of ...

 1.  What are the characteristics of the particles of matter? Solution: The characteristics of particles of matter are as follows: (a) Presence of intermolecular spaces between particles (b) Particles are in constant motion (c) They attract each other (d) All matter is composed of very small particles which can exist independently. Q2. Differentiate Solid, Liquid & gas? Solution: The difference in the characteristics of the three states of matter Characteristics Solid Liquid Gas Shape Fixed shape No Fixed shape No Fixed shape Volume Fixed volume Fixed volume No Fixed volume Intermolecular force Maximum Less than solids Very less Intermolecular space Very less More than solids maximum Rigidity/Fluidity Rigid/cannot flow Can flow/not rigid Can flow/not rigid Compressibility negligible compressible Highly compressible Convert the following temperature to Celsius scale: a. 300K          b. 573K Solution: a.  0°C=273K 300K=...

  Question 3: How did the rain change? What happened to Lencho’s fields? Answer: The rain started pouring down. But suddenly a strong wind blew and very large hailstones, like frozen pearls, began to fall along with the rain. Question 1: Was Lencho surprised to find a letter for him with money in it? Answer: No, Lencho was not at all surprised to receive a letter from God with money in it. He was very confident and had firm faith in God that his request would definitely be taken care of by the Almighty. Question 2: Why does the postmaster send money to Lencho? Why does he sign the letter ‘God’? Answer: The postmaster was deeply moved by Lencho’s faith in God. Hence, he decided to send some money to Lencho in order to avoid shaking the latter’s faith in God.  Question 2: Can you say how 10 May is an ‘autumn day’ in South Africa? Answer: South Africa is located in the Southern Hemisphere, i.e., below the equator. In the Southern Hemisphere, the timing of the seasons is different...

Joules Law oh heating effect   when a current 'i ' passes through a conductor of resistance 'r' for time 't' then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time Ohm's law states that  the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant . What are the factors affecting the resistivity of method? The factors like  temperature, alloying, cold work, age hardening & mechanical stress  affect the resistivity of electrical materials.

  What was the poet’s dilemma? Answer: The poet was standing before the two roads. He had to decide which one would lead him to success. It was not easy for him to decide What do the roads represent? Answer: The roads represent the problem of decision-making. Human beings suffer because of their choices and decisions. They find themselves in such situations at every step in their lives. Why did the poet choose that road? Answer: The poet chose that road because it was less travelled. He wanted to do those activities which had not been done by anyone earlier.
