Chapter 15: • Matter is anything that has mass and takes up space. – Ex: Your textbook‚ you‚ your pen/pencil‚ air‚ etc. • Classification systems are used all the time to organize objects. – Ex: The Periodic Table of Elements‚ organizing your locker‚ your clothes‚ etc. • In order to make the study of matter easier to understand‚ scientists have developed ways to classify matter. • The properties of materials can be used to classify them into general categories. – Ex: Pure substances‚ elements

IV Protected Area). Among these‚ the 28 Tiger Reserves are governed byProject Tiger‚ and are of special significance in the conservation of the tiger. Some wildlife sanctuaries are specifically named Bird Sanctuary‚ eg. Keoladeo National Park before attained National Park status. Many National Parks were initially Wildlife Sanctuaries. Wildlife sanctuaries of national importance to conservation‚ usually due to some flagship faunal species‚ are named National Wildlife Sanctuary‚ like National Chambal (Gharial)

Abstract: In this experiment‚ two object collided both elastically and in inelastically‚ the purpose of this experiment is to study the principle of conservation of momentum in collisions using two bodies. We also calculated the amount of kinetic energy in elastic and inelastic collisions before and after the collision. Introduction: When bodies collide with each other‚ the total momentum p = mv‚ is always conserved regardless of the type of collision provided no external forces are present. There

60-70% of the world’s total biodiversity exists. India has two out of the 18 biodiversity hot spots in the world. India has rich traditional knowledge and wisdom in the conservation of nature and natural resources. Religious beliefs‚ culture and folklore have together treated nature and environment with sanctity. Conservation and protection of environment and love for nature have always been part and parcel of Indian ethos and culture. Independent India has traveled a long way on the path

Soil Erosion And Conservation SOIL EROSION AND CONSERVATION Erosion Erosion is the removal of soil particles by the motion of wind or water. Soil erosion is one of the major concerns of modern agriculture throughout the world. The fallowing contributes to soil erosion: Misuse of land‚ Mismanagement of arable land‚ Indiscriminate felling of trees‚ Overgrazing‚ Poor soil and water management Erosion causes or Results in a: Decline in soil fertility‚ Water supply‚

QUESTION( Conservation of Energy) 1. Missy Diwater‚ the former platform diver for the Ringling Brother’s Circus had a kinetic energy of 15 000 J just prior to hitting the bucket of water. If Missy’s mass is 50 kg‚ then what is her speed? Solution: According to energy conservation‚ the kinetic energy at the bottom of the dive (15‚000J) is equal to her gravitational potential energy before the dive. We can use this fact to find her dive height: PE = mgh h = PE/mg = 15‚000J / (50kg)(9.81m/s²)

Agricultural Land Conservation The issues of land distribution and land conservation in agriculture attract more and more attention‚ especially when the expansion of cropland is hitting a limit since much more land is conserved for environmental purposes. Soil erosion is devastating the topsoil of land as chemical fertilizers are used to increase output within a limited amount of land. At the same time‚ livestock production expands at an ever-growing speed‚ worsening the land use situation.

Conservation is the practice of protecting plants or animals‚ and their habitats. These plants and animals may be very close to extinction. North America experienced a big loss of megafauna at the end of the Pleistocene era (about 13 000 years ago). This started a program known as “Pleistocene re-wilding”. Re-wilding involves the reintroduction of extant species into areas where they became extinct in the past. This program aims to restore the evolutionary and ecological potential that North America

Energy audit An energy audit is an inspection‚ survey and analysis of energy flows in a building‚ process or system with the objective of understanding the energy dynamics of the system under study. Typically an energy audit is conducted to seek opportunities to reduce the amount of energy input into the system without negatively affecting the output(s). When the object of study is an occupied building then reducing energy consumption while maintaining or improving human comfort‚ health and safety

Maggie Haas Reiter Honors Physic 8 March 2015 Background Information: Anything that has mass and is moving has momentum. Momentum is equal to the objects mass times its velocity. Momentum is conserved‚ which means that “momentum before an event equals momentum immediately after‚ or pi=pf”. Since pi=pf‚ then pai+ pbi = paf+ pbf and (ma* vai)+ (mb* vbi)= (ma* vaf) + (mb * vbf). Having velocity simply means that an object has a speed and direction. Using the formula “(ma * vai) + (mb * vbi)
