quantities are limited

Limitations of Dimensional Analysis - Dimensional analysis has no information on dimensionless constants. If a quantity is dependent on trigonometric or exponential functions, this method cannot be used. In some cases, it is difficult to guess the factors while deriving the rela..

The exhaustible natural resources are limited in nature and are liable to be degraded in quantity and quality by human activities. Examples are forests, soil, wild animals, minerals, fossil fuels et..

Question 1 - Question: How do you classify our natural resources? Answer: We can classify our natural resources into two categories: (a) Inexhaustible resources: Renewable resources such as solar radiation, air and water. (b) Exhaustible resources: Non-renewable natural resources which are availabl..

Water is an essential factor in photosynthesis. The effect of water can be understood by studying the yield of crops which is the direct result of photosynthetic activity. It is found that even slight deficiency of water results in significant reduction in the crop yield. The lack of water not onl..

Introduction - Physical world and Measurement - Physics is sometimes called as 'science of measurement'. The acceleration produced by a force for the motion of a body can be known by measuring the magnitude of applied force and mass of the body. Similarly, the distance of a stone covered, when thro..

Introduction - A Solution is a homogeneous mixture of two or more chemically non-reacting substances called components. The composition of the components can be varied with in certain limits. When two components are present - Binary solution. When three components are present - Ternary so..

) in water which produce harmful effect and decrease the usefulness of water. Human waste was the first water pollution problem since communities often drank from the same river in which they disposed their wastes. Human activities during the last century have polluted much of this limited..

Uncertainty in Measurement - When dealing with objects that can be counted, one can always get an exact answer. But while measuring the weight of a person, the volume of milk in a container, the length of a cloth etc. it is not possible to measure them exactly. The difference in the two situations ..

Impact of Misuse of Natural Resources - Natural resources characteristically exhibit two features. They are: 1) Physical limitations 2) Limitations of regeneration / production. Natural physical resources like geophysical, hydro-geological, edaphic, atmospheric resources exhibit..
