I want full periodic table diagram

Chemistry

September 18, 2014

Question

I want full periodic table diagram with number and name of elements

Akinropo - Nigeria (25365)

Answer

You can use the table in the Periodic Table lesson. By clicking on an element abbreviation, it will show its full name, number, and other facts.

Chemical Elements lists the elements with name and number.

A Periodic Table diagram with the full name of the element is too big to display here.

Why are TV screens dusty after a while?

Physics

September 17, 2014

Question

why are TV screens dusty after a while?

mahamed - Tanzania (25361)

Answer

When the electrons from inside the TV screen hit the surface, they collect charges on the screen. Those charges will attract dust particles and cause them to stick. The newer LCD or flat panel screens do not have that much of a problem.

Why does nylon crackle when I undress?

Physics

September 17, 2014

Question

why nylon cloths crackle as undressed?

mahamed - Tanzania. (25362)

Answer

When nylon rubs against the skin, it creates static electricity. The crackling you hear is caused by tiny static sparks coming from the nylon material.

Acceleration and speed

Physics

September 17, 2014

Question

1.If a car traveling at 25 m/s speeds up to 40 m/s over a period of 15 seconds what is the average acceleration?
2.An airplane that moves 50 meters in one second has a speed of, what?
3. rider finishes a 120-km bicycle trip in 3 hours. The average speed of the rider is, what?
I am having trouble with these, can you please help me out?

Rashana - USA (25363)

Answer

Acceleration is change in speed divided by time. Thus: (40 m/s - 25 m/s)/15 s equals 15/15 = 1 m/s^2

50 m / 1 s = a speed of 50 m/s

Since distance = speed * time, speed = distance/time. Thus 120 km/3 hr = 40 km/hr

Is every image in a Flash layer called a scene?

Flash

September 16, 2014

Question

Every image in the layer is called scene
Is this statement true or false according to macromedia flash

- India (25359)

Answer

The answer is false.

A Flash movie is a collection of Scenes. Just as in a TV show or real movie, each scene may have a different background or camera angle. Within a Scene, there may be several layers of images.

Note that it is no longer Macromedia Flash. It is now Adobe Flash.

Explain the nature of the soul

Religion

September 14, 2014

Question

I have read your article on the soul, very interesting but it does not explain the nature of the soul and its connection, (if any) with spirit.
What is the nature of the soul and what is it made of? It seems likely to me that he soul and spirit are the same. Anyway thank you for your consideration.

Chris - Canada (25351)

Answer

Ancient Greeks, such as Aristotle, separated the soul and spirit (or life-spirit). Many did not believe humans ever had a soul.

However, most modern people who believe in some religion also believe that humans have souls that exist beyond death.

The biggest problem concerning describing a soul or spirit is that it is purely theory or speculation. No one knows for sure, except through belief in a holy book, such as the Bible.

Ohm's law and DC generator

Physics

September 11, 2014

Question

ohms law is applicable for generator and how

upendra - India (25350)

Answer

The output current from a DC generator is I = V/R(i), where R is the internal resistance of the generator.

The current in the DC circuit is I = V/R, where V is the output of the generator and R is the resistance of the circuit.

Learning from Edison

Biographies

September 10, 2014

Question

what do you learn from the life of thomas edison

sandeep - India (25348)

Answer

Thomas Edison was ambitious and a hard-worker, even as a young man. He would see a need for something--such as newspapers for people who rode the train--and then sell them to his customers. He read much about science, was curious about things, and when he got an idea, he would work on it to completion.

These are good traits to have.

Later, when he was inventing things, he organized a research group to help him in his inventions. His business skills were very important.

Seeing what Edison did to make his inventions and his business, you can look at your own skills and apply them to become successful in your areas of interest.

Biblical interpretations of constellations

Religion

September 10, 2014

Question

I was born and raised up in west Texas where you can see the stars very clearly due to the reduction of big city lights. The Bible has several scriptures telling us to look to the stars.

Gen.1:14, says "the stars shall be for signs..."! What does any sign we look at beside our roads give us? They give us information that we can understand. So, God put the stars in special patterns that we could easily recognize.

One important pattern is the Northern Cross which is close to the North Star. If you google, the Northern Cross in color, you should be able to make out the shadowy figure of a man nailed to this cross. This shape of the cross in the same shape of the ancient Hebrew hieroglyphic letter, "tav", which means, "sign".

If you write the most ancient shape in Chinese for a tree, you first draw the shape of a cross. The Bible says, "cursed is he that hangeth upon a tree". Jesus took our curse of sins upon himself being nailed to the cross or tree that formed the cross.

The ancient Karahunj stones were seen by many ancient cultures as an entry into the heavens after their death. Many of these stones have holes in them that point to Cygnus which is actually meant by God to be seen by us as the cross of Christ. This was all planned from the beginning.

Psalms 19;1-4, says, "the heavens declare the glory of God". So, the Bible has many scriptures about the importance of constellations as a proof sent to us by God as signs. Check out Isa. Chapter 40. If you want to see more on this subject then google, Aquilla Fleetwood, Night Signs. These patterns of constellations have only moved slightly since creation. Thanks

Aquilla - USA (25349)

Answer

Thank you for sharing your information on the religious interpretation of the constellations of stars in the sky.

Although many constellations were names by ancient Greeks, from your information, there are Biblical interpretations too.

Maintain good grades

Grades

September 9, 2014

Question

how to maintain good grades

honey jell - Phillippines (25346)

Answer

If you have received good grades in previous classes, consider how you got those grades. Was it because you were more interested in the class or perhaps more skilled? Did you have a teacher you liked? These are various factors.

Each class is different, so you have to make an effort to relate with your teacher and set a good schedule for doing your homework.

If you got good grades before, you can get good grades again. You can even get better grades with some good strategy and effort.

Best wishes on getting good grades. I know you can do it.

Astronomy

Question

Hi,

I’m a home school instructor and I took my kids to the Adler Planetarium a few weeks ago on a field trip. Our kids had fun learning about the solar system and the moon. I used this guide as a reference (http://bebusinessed.com/telescopes/) and I think it would make a good addition to your page here: http://www.school-for-champions.com/astronomy/resources.htm

I hope this was helpful.

Salutations!

Pendulum equation

Physics

September 6, 2014

Question

what is the effect on the period of the pendulum when the experiment is repeated with
1.aheavier pendulum bob of the same size.
2.a larger number of oscillations
3.a smaller angle of swing
4.a longer pendulum

monika - Bangladesh (25340)

Answer

The pendulum equation is: T = 2pi*SQRT(L/g), where T is the period in seconds, pi = 3.14, SQRT is the square root, L is the length of the wire, and g is the acceleration due to gravity = 9.8

In a simple pendulum, the weight of the bob is not a factor.

The period is how long it takes to swing back and forth. That can determine the number of oscillations.

With little or no friction, a smaller angle would not change anything except the amplitude of the swing.

The greater the length of the wire, the greater the period.
