Author: Haoyang Chen Date: 2/23/2013 Experiment No.: 2 Title: Synthesis - A Square Wave‚ a Musical Note and Sound Cancellation Introduction: In this experiment‚ we will do three parts to find out the synthesis sound. They are a Square Wave‚ a Musical Note and Sound Cancellation. For the first part‚ it is the superposition of sine wave. We are going to construct a square wave (approximately) by adding together some pure tones of different frequencies. This stretched string vibrating at

PASSIVE SOLAR INTRODUCTION Passive solar is a “GREEN BUILDING “technique‚ which depends on natural convection process rather than mechanical transmitting source‚ which captures the heat energy of sun and delivers it during winter and pumps out the heat in summer‚ using heat distribution methods. Some of the heat distribution methods are Convection‚ Conduction‚ and Radiation. However components of passive solar heating are‚ the aperture area of the house‚ absorber area of the house‚ thermal mass of

Savannah Hudon Mrs. White English IV 2 February 2014 (Intro) Solar Energy is an underrated renewable energy source. We should be looking to make advances to become more dependent on renewable energy sources such as solar energy. The more we rely on these new energy sources the more carbon dioxide‚ sulfur dioxide‚ and other greenhouse gases we could eliminate from the air which will help ensure a clean and safe environment for future generations. In addition‚ it could aid America to depend

INTRODUCTION When thinking of starting a contracting business for solar panels‚ many economic issues and concerns play a factor in the decision making process. Having a concern for the environment and knowing that solar panels have a cost saving for both households and business seems to be reason enough to start a business. However‚ before making such a financial investment you should first take a look solar panels in the economy in terms of (i) GDP growth rate‚ (ii) interest rates‚ (iii) level
