Background Gravity/Freefall: Every object on the Earth’s surface is pulled towards the center of the earth by the force of Gravity. Gravity causes all objects in Freefall to accelerate downwards at the same rate, regardless of the object’s mass. On Earth, acceleration due to gravity is constant of 9.81m/s^2. Therefore on Earth when air resistance is not present, all objects fall at the same acceleration of 9.81m/s^2. However, on the planet Vela Rani, the value of acceleration due to gravity is…

In the 21st century, global warming, which is caused by the increase of carbon dioxide gases that forms from burning fuels in the atmosphere, is a serious threat to the Earth. As National Renewable Energy Laboratory (2006) statistics show, energy consumption is done principally by buildings in the U.S. This research intends to decrease the percentage of carbon emission by developing zero carbon homes. Berry,S. et. al. (2013) define zero carbon homes as having no need for fossil fuel for heating…

journalist Elizabeth Kolbert discusses New Zealand’s problem with invasive species attacking endemic fauna which results in many of their native species becoming extinct. Kolbert explains the problems of exterminating specific animals such as stoat for conservation of their natural wildlife. She also explains the issues of how explorers brought various animals to different parts of the world. Hence, Elizabeth Kolbert discusses the difficulty of eliminating invasive species and that extreme…

We champion the essence of ecotourism by pledging to consistently and diligently foster conservation, empower local communities, and educate visitors on the native culture and natural beauty of the location. An example of EcoTrue remaining true to our mission statement is reflected in our Maquipucuna Reserve project. The Maquipucuna Reserve…

to learn about the anatomy, physiology, and obscurities of every phylum, through dissections and field work. As my knowledge and respect for wildlife and conservation grew, I was given the opportunity to be the cartographer and artist for the Washtenaw Community College Nature Trail that was put into place this year for education and conservation efforts in the natural habitat for the many species that surrounds the campus. When I transferred to Cornell, I was ready…

RESULT AND DISCUSSION 1. Hardware testing A prototype of street lighting automation system is developed and the whole prototype design is as shown in Figure-9. The design of whole project was done with 12 LEDs, 4 PIR sensors and 1 LDR sensor. All the wiring and connection are connected to Arduino board. This was done by calibrate part by part which is started with LDR sensor, then PIR sensor and lastly LED as light module. During day, all LEDs and PIR sensor is turned off. This condition is…

Introduction Corporations acknowledge that the application of sustainability practices is essential for their long term business viability. Sustainability practices promote efficiency by reducing waste, keeping and improving human capital, and delivering reasonable profits to shareholders. Wal-Mart and Starbucks implemented comprehensive sustainability practices that are shared across all the areas of these organizations. One way to analyze Wal-Mart 's and Starbucks ' sustainability approaches…

As we live our daily lives, we are only concerned about our own problems and forget about what the rest of the world is going through. We disconnect ourselves from the reality and focus on what only affects us directly. We hear stories about how there are people all around the world who do not have food to eat, water to drink, a bed to sleep in, and how animals are going extinct because of humans. Although hearing situations like these will make the audience feel some amount of empathy,we still…

He relays every negative thing about our environment and health to our increased dependence on cars. Brown seems to cry out to the world that we need to change our ways before it’s too late. He wants people to be more mindful, and to not just throw out the environment. Brown begins his argument with a stroll down the authors’ childhood. He refers to the numerous afternoons spent strolling with his grandmother to the local grocery store. Many people can refer to this as an emotional appeal.…
