Moment of Inertia 1. Abstract The goal of this study is to understand the transfer of potential energy to kinetic energy of rotation and kinetic energy of translation. The moment of inertia of the cross arm my group measured with the conservation of energy equation is: 0.01044 kg/m2 (with the mass of 15g)‚ 0.01055 kg/m2 (with the mass of 30g)‚ which is kind of similar to the standard magnitude of the moment of inertia of the cross arm: 0.0095 kg/m2 (Gotten by measuring the radius and the mass

Renewable Energy Summary Renewable energy flows involve natural phenomena such as sunlight‚ wind‚ tides‚ plant growth (biomess) and geothermal heat. According to the International Energy Agency (2002)‚ “Renewable energy is derived from natural processes that are replenished constantly. In its various forms‚ it derives directly from sun‚ or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar‚ wind‚ ocean‚ hydropower‚ biomass‚ geothermal

Premium Nuclear power Renewable energy Energy development
Nuclear energy originates from the splitting of uranium atoms in a process called fission. At the power plant‚ the fission process is used to generate heat for producing steam‚ which is used by a turbine to generate electricity. Nuclear energy usually means the part of the energy of an atomic nucleus‚ which can be released by fusion or fission or radioactive decay. What are the Benefits of Nuclear Energy Nuclear energy is the world’s largest source of emission-free energy. Nuclear power plants

Energy Management and Audit Report 1) Introduction For over the past few years‚ the planet Earth is being damaged by human activities. Buildings play a major role in that. They contribute to approximately 40% of the greenhouse gas emissions globally. Over the past 30 years‚ 10% of the ice burgs have been melted due to the rising temperature of Earth. The rise in temperature is caused by greenhouse gas. Therefore‚ green building is important today. Green building has both positive and negative

PERIODS 4 - 6 PERIOD 4: During period 4 it was apparent that we maintained our primary focus on the grocery stores since the majority of our sales force was there. Realizing that it was one of our biggest marketers‚ we continued to increase in this area (increasing by 8% during this period). We realized at this point that when looking at sales force numbers‚ we were one of the lowest ones and we thought that if we could bump our total sale force from 183 to 190‚ and then for our next decision
