Develop hypotheses predicting the effect of pyrite and coal on the acidity of water? a. Pyrite hypothesis = If pyrite is added to water, it will make the water more acidic. b. Coal hypothesis = If the activated carbon is added to the water, it will make the water more acidic. 2.

Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how you determined this. Direct vs indirect accept/reject =Rejected. The motor was just as fast when the solar panel was set up at a 45 degree angle Direct vs reflected accept/reject = Accepted. When the foil was reflected at the solar panel, the motor moved faster. Direct vs shaded accept/reject = At 25% shading-Rejected-The motor moved just as fast as when the solar panel was completely exposed to sunlight. At 50%-Accepted-The motor moved slower than when the solar panel was completely exposed to sunlight (speed medium to fast) At 75%-Accepted-The motor moved very slow compared to when the solar panel was completely exposed to sunlight (Very slow) Direct vs filtered accept/reject = Rejected-Upon being covered by the red, yellow, green, and blue cellophane, the motor moved the same as in direct sunlight 3. Does increased exposure to the sun’s light produce more current? Explain how you know this based on your data. Answer = YES. The more exposure the solar panel had to the sun, the faster the motor moved. Through a variety of trials with the solar panel and exposure to the sun, it was determined that the more exposure the solar panel had, the
"You can reduce the upfront cost of your solar panel system by 30% to sometimes more than 50% by
2. Choose one of the research questions from above and consider it in more detail. Based upon the question, what would be a reasonable hypothesis?
1. Using the information provided in the Introduction and your observations from Part 1, hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint.
In order to determine if switching to solar is the right decision to make, learning more about energy production is an important step. To do this, it is best to focus on some particular areas when conducting research. These areas are discussed further below.
With the reduction of the dependence on fossil fuels, countries and citizens are looking for a way to fulfill their energy needs. Many turn to solar
With the increasing costs, both financial and ecological, of fossil fuels, fuel efficiency in vehicles has become an increasingly important factor. Vehicle manufacturers and designers are exploring alternative fuels, with electric, hybrid and hydrogen-powered vehicles being looked at as viable alternatives. Solar power has been somewhat overlooked but has the ability to become widely used because it is both clean and economical. The advantages over fossil fuels are obvious: Solar power is renewable, cannot be exhausted and doesn’t cause pollution. Fossil fuels are becoming increasingly scarce and expensive. Solar seems like a logical alternative. As such, it is being considered by private companies and government think tanks as a partial
Solar power is energy from the sun that is collected via solar panels that can sit on roofs of buildings or in large fields called solar fields. These panels will be placed at the angle where the sun will be able to reflect off it the most and the strongest. In this research how this solar power impacts the coal industry will be explored and explained.
Humans are destroying Earth’s atmosphere with the use of fossil fuels. Solar panels are a fantastic alternative, and could save our planet. In 1977 Jimmy Carter began his term as President of The United States. Carter, a firm believer in solar technology, decided to start immense studies about solar energy and it’s benefits. He did so in hope of convincing congress of passing a bill to encourage investing in solar energy with the help of government funds. Such studies received funding of the amount of $124 Million in 1980; Needless to say, this was a huge step towards creating a nationwide movement to sustain renewable energy sources with low pollution outputs.
It is reassuring to see that solar energy is getting accepted widely by more and more people everyday and is finding newer applications and uses with every passing day. Apart from the already popular and widespread domestic use of solar power, it is also being used extensively in various other fields such as agriculture, architecture, urban planning, solar lighting, solar thermal, solar chemical, solar vehicles, cooking and so on. Based on how solar power is being used, it can be broadly divided into two
The use of solar energy has grown many folds. Developments in the field of solar have helped
(Q4) From this part of experiment, we don’t get any constant continuous reading on the multimeter. There are a few readings flash on the screen, but we don’t consider them as experiment data. Solar cell should act as a battery, and the current should be
Have you ever been to a house or business that uses Solar? Solar power is a great way to save money as well as conserve energy. Solar panels convert sunlight into usable energy for housing, businesses, sections of properties, and even stuff like pool equipment. I want to discuss out the three important points about photovoltaic panels starting with the history of solar panels to understanding panels and how they are built, and finally the environmental aspects of photovoltaic panels.
The research and development of solar power and other new renewable technologies such as wind and marine will continue to move in two major directions: cost reduction (Figure 16) and intermittency elimination.
The limited resources of non-renewable energy and the fluctuation of fuel price have forced the world to find clean and economical natural energy resources by means of renewable energy. Solar energy is a sustainable alternative option that can be utilized in various ways and can be used in many applications.
Founded in 1987 by a professor of electrical engineering at the University of Stanford, the SunPower Company has lived to beat adversities and emerged as a formidable force to reckon with in the provision of solar energy in the past few decades. Markedly, Dr. Richard Swanson acted on a market gap and spearheaded the company’s establishment from a research and development corporation to a fully-fledged production firm that produces and sells solar panels globally. Owing to worldwide warming and climate change, there have been entrants in the same line of business that compete with SunPower. As a result, a reduction in the company’s market share occurred over the past decades.
