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)

Introduction: Why Study Medicinal Plants 4. Medicinal plants are resources of new drugs. It is estimated there are more than 250‚ 000 flower plant species. 5. Studying medicinal plants helps to understand plant toxicity and protect human and animals from natural poisons. 6. Cultivation and preservation of medicinal plants protect biological diversity‚ for example metabolic engineering of plants.

diaries of Jean-Marc-Gaspard Itard‚ The Wild Child is a movie made in 1970‚ with a setting in France from the18th century‚ and based on a child who had lived in nature his whole life without any human contact. Itard‚ a well known French doctor for working with deaf-mutes‚ had taken in this feral child under his care for the purposes of his studies on the child’s intellectual and social education. Given the time period of the movie Itard had taken the "wild-child" in under his own care‚ and helped

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

Wild Children In the beginning of the 1920’s‚ Russia was controlled by a communist era. Everyone struggled to survive in a country they have considered their own. Parents were taken away‚ children were stolen from homes. Everyone was oppressed from the right to live freely. Felice Holman‚ author of the book the Wild Children centers her book on how the children of Russia in the 1920’s sought refuge to survive and pushed through the limitation of childhood caused by societal revolution especially

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)
