In arsenic contaminated areas of the Ganga–Meghna–Brahmaputra (GMB) plain (area 569 749 sq. km; population over 500 million) where traditionally cow dung cake is used as a fuel in unventilated ovens for cooking purposes‚ people are simply exposed to 1859.2 ng arsenic per day through direct inhalation‚ of which 464.8 ng could be absorbed in respiratory tract. Introduction Arsenic has been considered as a human carcinogen and causes multiple adverse health effects.1 Groundwater arsenic contamination

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

Advantages and Disadvantages of Renewable Fuels Solar Energy: Advantages: -Energy is free although there is a building cost. -Causes no pollution‚ however‚ energy may go into machines that produce pollution. -Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid. -Estimated that the worlds oil reserves will last for 30-40 years whereas solar energy is infinite. Disadvantages: -Solar energy can only be harnessed when it is daytime

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)

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

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)
