Class Improvements I would first like to say that I really enjoyed being in your class. You are very energetic teacher and you keep the class interested, laughing and most important awake! I like that fact that you actually care and that you put more effort into your students. Your class is hard but esay at the same time. If you just do the work and stay focused you will pass the class. You also give opportunities for extra credit, which for me and most other students is a good thing. I like the fact that you give two chances to pass your online quizes. When you are lecturing the class I like how you tell us what we should write down. I really like the fact that you go over the tests and you tell us students what will be on the test so we know what to study and what not to worry about. I also like how you made your own work book as another sorce to help us study for your tests. The fact that you put up the test essay questions is another big factor that helps us to better on your tests. Some improvements that might benefit your next class. You should think about adding group projects so that the students are a little more interactive with each other. I also think that the movie you showed us was very interesting and you should offer extra credit or make it an assignment of some sort. I think showing a power point of your lecture or what you are going over in class might help students take better and more efficient notes. There aren't really that many…
Energy works all in different ways, whether when you wake up with full boost of energy to go for a run or just turning on a light bulb. There are plenty of other things we need energy but most wasn’t able without someone designing it or creating it. Which is why we have energy workers, these people day by day find source full ways to supply us with energy. They every year come up with ways to help save energy but still be the same amount you did the year before. Life wouldn’t be the same without…
The demand for energy in form of electricity is increasing across the world. The estimated consumption of electricity which was 13250 Twh (Terawatt Hours) in 2007 is expected to rise to 40000 Twh in 2040. With increasing focus on generating electricity from green sources, the gap between electricity supply and demand will grow even larger. If the gap between demand and supply is not closed in a cost effective manner, either the price of electricity to the end consumers will go up or the governments…
The principal of 9,984.31 dollars was invested in my portfolio consisting of 7 securities from 6 different industries including telecommunications, retail, energy, etc. The beta targeted was 0.8 (0.78) to maintain a safe investment involving less risk. My risk-averse approach brought me the following results;
The Expected Return on my portfolio is;
EX RETURN = RF + BETA X RM – RF
= 0.0550 + 0.78 x 9.89 – 0.0550
(0.0550 = RF 1 YEAR US) (RM = 9.89 RETURN ON MARKET (1 YEAR DOW JONES INDEX))…
Petroleum Poses Precarious Problems Presently
The world’s energy crisis is here and it is a problem that will not go away unless action is taken to correct the damage that has been done. Facts only do justice to the predicament that has been caused by excessively using Earths natural resources. In the years before coal and fossil fuels being used as a primary resource of energy the Earth was in equilibrium and the thought of climate change was nonexistent. The world is responsible for consuming…
Chemical potential energy: stored energy.
4. Chemical energy: potential energy stored in chemical bonds or compounds
5. Displacement: vector quantity that measure change in distance, direction or position of an object.
6. Distance travelled: scalar quantity that measure how far and object has moved.
7. Efficiency: ratio of how useful work output to the total work input.
8. Elastic potential energy: energy stored in an object that has it shape changed by stretching.
9. Electrical energy: work done by…
Whenever you conserve energy you not only save money, you also reduce the demand of fossil fuels such as coal, oil, and natural gas. Less burning of fossil fuels also means lower emissions of CO2, the primary contributor to global warming, and other pollutants.
Energy Conservation refers to reducing energy consumption through using less of an energy service. Energy conservation doesn’t differ from efficient energy use, which refers to using less energy for a constant service. This means…
P6: TYPES OF ENERGY
WHAT IS ENERGY?
The ability to do work is known as energy. There are different types of energy:
1. Mechanical: Mechanical energy can either be kinetic energy or potential energy. E.g.
A moving car possesses mechanical energy due to its motion (kinetic energy). This energy is then mainly converted to kinetic energy and some wasted as sound and heat energy.
Mechanical energykinetic energysound and heat energy
A drawn elastic band posse’s mechanical energy due to its stretched…
OVERVIEW OF ENERGY EFFICIENCES
There has been much focus over the past decade by the Government and the media regarding the benefits of renewable energy. All across the Midwest and Western United States, utility companies are benefiting from federal subsidies and tax credits to build wind farms and installing solar panel systems. Unfortunately, wind and solar still have major limitations. The unpredictability of wind farms force Utility companies to “cycle” coal plants, making them operate inefficiently…
