This model set is based on old model. But it is very helpful for the students who appearing in see examination. Keep on practicing! Good luck! for the exam.
2. What is meant by organizational development? Discuss important aspects of organizational development. Organizational development is the process of making positive changes in economic, business and resource resources as per the need. As the organization is a dynamic, relative and objective tool, it should be continuously improved and modified as per the needs of the country. In order for any organization to succeed, it must improve or develop in its various aspects. Aspects of organizational development A) Development in structural system / side . To make the structure work-oriented, service-oriented, simple and fast, . To restructure scientific, rational and practical organizational units, . Strengthening the control and coordination system B) Policy reforms . Timely amendments to policies, rules and laws, . Improving goals, objectives and strategies as time demands, . Adoption of new management concepts, C) Development in the work process . To make decentralized and accountable . S...
Those animals which have no backbone or vertebral column are called invertebrates. They are classified into nine phyla. Characteristics of the animals of these phyla are given below: 1. Phylum: Protozoa i. They are unicellular organisms. ii. They are mostly found in water. iii. These animals have pseudopodia, flagella or cilia for locomotion. iv. They can be free living or parasitic. Some examples: amoeba,paramecium etc 2. Phylum: Porifera i. Porifera means pore bearer animals, commonly called sponges. ii. Most of them are marine organisms except spongilla. iii. They are diploblastic animals. iv. They respire through general body surface. V. They do not move from place to place, so they are called sessile. vi. The presence of calcium and silicon makes their body rigid and strong. vii. Sponges have two types of openings on their body surface i.e. ostia(mouthlets) and osculums(anus). Some examples: sycon, spongilla,euspongia etc. 3. Phylum: Coelenterata i. The body of ...
Acceleration due to gravity(g) Acceleration due to gravity is defined as the acceleration produced in a freely falling body due to earth's gravity. It is denoted by 'g'. Its SI unit is m/s*2 and its average value on the earth's surface is 9.8 m/s*2. Relation between radius and acceleration due to gravity of earth Let M be the mass of the earth with its radius R. If a body of mass m is on the surface of the earth. According to the Newton's universal law of gravitation, we get F= GMm/R*2 ......(i) Here F represents the force by which the body is attracted towards the earth. So, F represent the weight (W) of the object. ie. W=GMm/R*2 ......(ii) We have, from the Newtons second law of motion, W= mg ......(iii) Hence from equation (ii) and (iii) we get, mg= GMm/R*2 g = GM/R*2 ....(iv) Equation (iv) is the expression for the acceleration due to gravity...
