Preface

Over the years, I have published a large number of tutorials in the areas of computer programming and digital signal processing (DSP). As I have time available, I am converting the more significant of those tutorials into cnxml code and re-publishing them at cnx.org .

In the meantime, this is one of the pages in a book titled ITSE2317 - Java Programming (Intermediate) that presents PDF versions of the original tutorials to make them readily available for Connexions users.When I have time available, I plan to update this tutorial and to re-publish it as a standard page at cnx.org .

This tutorial may contain internal links to other tutorials that I have written and published somewhere on the web. Those links may, or may not still begood. In any event, if you search cnx.org for the tutorial by title or by topic, you will probably find a clean copy of thereferenced tutorial at cnx.org . If not, you can probably use a Google Advanced Search to find a copy somewhere on the web.

The representation of program code in PDF documents is often very unreliable. Click here to download a zip file containing a clean copy of the program code discussed in this tutorial.

Questions & Answers

A golfer on a fairway is 70 m away from the green, which sits below the level of the fairway by 20 m. If the golfer hits the ball at an angle of 40° with an initial speed of 20 m/s, how close to the green does she come?

Chemistry is a branch of science that deals with the study of matter,it composition,it structure and the changes it undergoes

chemistry could also be understood like the sexual attraction/repulsion of the male and female elements. the reaction varies depending on the energy differences of each given gender. + masculine -female.

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
