NCERT Solutions for Class 9th: Ch 15 Improvement in Food Resources
NCERT Solutions for Class 9 Science Chapter 15 – Improvement in Food Resources all living organisms need food. Food supplies proteins, carbohydrates, fats, vitamins and minerals, all of which we require for body development, growth and health. Both plants and animals are major sources of food for us. We obtain most of this food from agriculture and animal husbandry. The improvement in food resources includes both enhancing the quantity and quality of food resources
Efforts have been made to fulfil the required nutrition of the growing population. This has been done in the form of green revolution, white revolution and green revolution. But, these have caused loss of natural resources. Manure and fertilizers are the main sources of nutrient supply to crops. Organic farming is a farming system with minimal or no use of chemicals as fertilizers, herbicides, pesticides etc. and with a maximum input of organic manures, recycled farm wastes, and bio-agents, with healthy cropping systems. Mixed farming is a system of farming on a particular farm which includes crop production, rising of livestock etc. Mixed cropping is growing of two or more crops simultaneously on the same piece of land. Growing two or more crops in definite row patterns is known as inter-cropping.
NCERT Solutions for Class 9th: Ch 14 Natural Resources
NCERT Solutions for Class 9 Science Chapter 14 – Natural Resources the resources available on the Earth and the energy from the Sun are necessary to meet the basic requirements of all life-forms on the Earth. These are the land, the water and the air. All these resources are discussed one by one. Air is a mixture of many gases like nitrogen, oxygen, carbon dioxide and water vapour. Role of atmosphere as climate controller is discussed. After that, wind formation is discussed. Movement of air form land to sea and sea to land is discussed.
Uneven heating of air over land and water-bodies causes winds. Evaporation of water from water-bodies and subsequent condensation give us rain. The fossil fuels like coal and petroleum contain small amounts of nitrogen and sulphur. When these fuels are burnt, nitrogen and sulphur too are burnt and this produces different oxides of nitrogen and sulphur. Rainfall patterns depend on the prevailing wind patterns in an area. Various nutrients are used again and again in a cyclic fashion. This leads to a certain balance between the various components of the biosphere.
NCERT Solutions for Class 9th: Ch 13 Why do we Fall Ill?
NCERT Solutions for Class 9 Science Chapter 13 – Why do we Fall Ill? is an Health and disease in human communities are very complex issues. In our organs or tissues, there are various specialised activities going on – the heart is beating, the lungs are breathing, the kidney is filtering urine, the brain is thinking. All these activities are interconnected. For healthy well-being, it is very important every organ of human beings should work properly. In this chapter the term health is defined and explained. Health is a state of physical, mental and social well-being. The health of an individual is dependent on his/her physical surroundings and his/her economic status.
Diseases are conditions in which there is lack of physical, mental and social well-being. Different types of diseases are explained. Diseases are classified as acute or chronic, depending on their duration. Disease may be due to infectious or non-infectious causes. Infectious agents belong to different categories of organisms. These organisms may be unicellular and microscopic or multi cellular.
The category to which a disease-causing organism belongs decides thE type of treatment. Infectious agents are spread through air, water, physical contact or vectors. It is important to note down. Prevention of disease is more desirable than its successful treatment. Infectious diseases can be prevented by public health hygiene measures that reduce exposure to infectious agents. Infectious diseases can also be prevented by using immunization. Effective prevention of infectious diseases in the community requires that everyone should have access to public hygiene and immunization
NCERT Solutions for Class 9 Science Chapter 12 – Sound is a form of energy which produces a sensation of hearing in our ears. Different types of sound we hear in our day to day to life. These are the sounds of bird, horn of cars, children crying around and many more. There are also other forms of energy like mechanical energy, light energy etc. We know that energy is conserved and can change its form. When we clap, the mechanical energy is converted into sound energy. Sound is produced due to vibration of different objects. Sound travels as a longitudinal wave through a material medium.
Sound travels as successive compressions and rarefactions in the medium. In sound propagation, it is the energy of the sound that travels and not the particles of the medium. Sound cannot travel in vacuum. The change in density from one maximum value to the minimum value and again to the maximum value makes one complete oscillation. The distance between two consecutive compressions or two consecutive rarefaction is called the wavelength, λ. The time taken by the wave for one complete oscillation of the density or pressure of the medium is called the time period, T. The number of complete oscillations per unit time is called the frequency. It is 1/(Time Period).
NCERT Solutions for Class 9th: Ch 11 Work and Energy
NCERT Solutions for Class 9 Science Chapter 11 – In previous chapter, we have discussed about force, motion and gravitation. Another concept that helps us understand and interpret many natural phenomena is ‘work. We need energy for other activities like playing, singing, reading, writing, thinking, jumping, cycling and running. Activities that are strenuous require more energy. Work and energy are related. Both are explained one by one. First, the concept of work is to be understood. Definition of work done is different from day to day life. Work is defined for a force.
Work is defined as force multiplied by displacement. If there is no displacement, we say there is no work. The concept is dealt here. SI unit of work done is joule. 1 Joule of work done is defined as if 1 Newton of force make a displacement of 1m in direction of applied force. It is important, in displacement direction is considered. If the force and displacement are in same direction the work done is positive. If force and work done are perpendicular to each other, work done is zero. If displacement is made in opposite direction of force applied, the work done is in opposite direction. Energy is defined as capacity to do the work. The Sun is the biggest natural source of energy to us. How does an object with energy do work? An object that possesses energy can exert a force on another object.
When this happens, energy is transferred from the former to the latter. The second object may move as it receives energy and therefore do some work. The unit of energy is, therefore, the same as that of work, that is, joule (J). 1 J is the energy required to do 1 joule of work.
NCERT Solutions for Class 9 Science Chapter 10 – Gravitation In previous chapter it is discussed force is required for motion. We have learnt that a force is needed to change the speed or the direction of motion of an object. We always observe that an object dropped from a height falls towards the earth. We know that all the planets go around the Sun. The moon goes around the earth. In all these cases, there must be some force acting on the objects, the planets and on the moon. Sir Isaac Newton figured out that force responsible for all these things is Gradational force. The gravitational force is force acting between two bodies due to their masses.
The chapter starts with the concept of gravitation. After that Universal Law of Gravitation was discussed. The gravitational force acting between two bodies is directly proportional to the product of their masses and inversely proportional to the square of distance between them. The gravitational force is responsible for motion of planets, free fall of any object, tides in oceans. Whenever objects fall towards the earth under this force alone, we say that the objects are in free fall. g is signified as acceleration due to gravity. it decrease with increase in altitude. If two bodies are thrown from same height, irrespective of their masses both of them will fall together with same acceleration due to gravity g. Equations of motions can be written accordingly. The concept of mass and weight is discussed.
Mass of an object is the measure of its inertia. Weight is gravitational force acting on the body. For body of mass m, weight is mg, where g is acceleration due to gravity. g is depends upon mass of earth and radius of earth. So, value of g will vary with that. Moon is having lesser mass and radius than earth. Value of g is 1/6 th of earth at moon. So, weight of any object on moon will be 1/6 th of his weight at earth, though the mass will remain the same. It is important to understand the difference between mass and weight.
NCERT Solutions for Class 9th: Ch 9 Motion Force and Law of Motion
NCERT Solutions for Class 9 Science Chapter 9 – Force and Law of Motion about Motion was discussed in previous chapter. What causes motion? A ball on the ground, when given a small hit, does not move forever. Such observations suggest that rest is the “natural state” of an object. This remained the belief until Galileo Galilee and Isaac Newton developed an entirely different approach to understand motion. In force, both magnitude and direction is considered. Concept of balanced and unbalanced force is discussed. In balanced force, net force is zero, as equal magnitude of force is applied from opposite sides. Net force is zero.
In unbalanced force, net force is not equal to zero. For change of state from rest to motion, or motion to rest, or to change velocity of an object, unbalanced force is required. So, this much is the concept of force. Newton’s laws of motion are discussed after that. First law of motion: An object continues to be in a state of rest or of uniform motion along a straight line unless acted upon by an unbalanced force. The natural tendency of objects to resist a change in their state of rest or of uniform motion is called inertia. The first law is also known as law of inertia. The law has been explained with several examples. The mass of an object is a measure of its inertia.
Its SI unit is kilogram (kg). Force of friction always opposes motion of objects. Second law of motion says, The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force. From this, it can be derived force = mass multiplied by acceleration. The SI unit of force is kg m s – 2 . This is also known as newton and represented by the symbol N. A force of one newton produces an acceleration of 1 ms –2 on an object of mass 1 kg. The momentum of an object is the product of its mass and velocity and has the same direction as that of the velocity. Its SI unit is kg ms –1 ,also known as Newton. Third law of motion says, To every action, there is an equal and opposite reaction and they act on two different bodies. In an isolated system (where there is no external force), the total momentum remains conserved.
