Previous lessons provided an overview of Java Beans and developed a skeleton Bean program. A previous lesson also provided a test program to test the skeleton Bean. This lesson will show you how to place that skeleton Bean in the JavaSoft BeanBox and how to use the BeanBox to test it.

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 JavaBeans Components 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.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

What is the direction and net electric force on q_{1}= 5µC located at (0,4)r due to charges q_{2}=7mu located at (0,0)m and q_{3}=3\mu C located at (4,0)m?

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

velocity can be 72 km/h in question. 72 km/h=20 m/s, v^2=2.a.x , 20^2=2.a.50, a=4 m/s^2.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

how do lnternal energy measures

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.
Dlovan
Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).

specific heat capacity is the amount of energy needed to raise the temperature of a substance by one degree Celsius or kelvin
