Exponent of large number

Algebra

July 20, 2014

Question

Is there a simple solution to know the ans of any digit raise to power as-
2^5123 or
9^984
Without multiplying it 984 times

Sushant - India (25131)

Answer

Both of those numbers would be extremely large. I'm not sure of the point in getting such an answer.

Usually, you can get the answer by using the calculator that comes with your computer. Change the View to Scientific and then enter the first number--like 9--and use the x^y button to enter 984 and get your answer.

Unfortunately, with such a large number, you would an answer in the exponential form, something like 9.43255...e+938.

Wants to use results in dissertation

Education

July 16, 2014

Question

Hello, I am currently working on developing a survey for students with learning difficulties. I am doing this as part of my dissertation in Speech-Language Pathology. I am asking your permission to use modified versions of some of your questions for my research. Also did you assess the survey itself?

Thank You,

Brian - USA (25115)

Answer

Feel free to use modified versions of our questions in your dissertation. I would appreciate it if you would cite the source.

I really haven't done a scientific analysis of the results.

Best wishes for success in your dissertation.

Liked article on revenue models

eCommerce

July 15, 2014

Question

Hi there,

I was on the hunt for some ecommerce business model articles to cite in a blog post I am writing about dropshipping.

I really like the article that you wrote about Revenue models.

I actually just put together an infographic on what ecommerce businesses are worth and how to value them.

Thought it might be down your alley about what ecommerce businesses are worth today.

Wondering if you'd like to check it out? :)

Paul - Australia (25114)

Answer

I'm glad you liked the article on revenue models. It would be interesting to see the results of your research.

Where do AC electrons go?

Physics

July 14, 2014

Question

The diagram (above) showing how AC moves through transmission wires is missing.

If the electrons move back and forth how do they go anywhere?

Drew - Australia (25111)

Answer

The animation showing how AC electrons move back and forth in a wire requires a Flash plugin. I plan to have a new animation without requiring Flash soon.

While in a DC circuit, electrons enter the battery or DC generator at the (+) terminate and exits at the (-) terminal. But in an AC circuit, the electrons simply move back and forth in the wire, starting at the AC generator. The motion of the electrons--and their electromagnetic waves--then power any devices in a circuit.

What causes frictional force?

Physics

July 14, 2014

Question

my question is regarding frictional force.
what cause frictional force between two surface in contact?

is it adhesive force or interlocking between hills and dales on rough surface?

mohan - India (25112)

Answer

The resistance due to friction is caused by electrical adhesion of the surfaces, as well as surface roughness, and in same cases deformations on a surface. See: Causes of Friction for more information.

How to find sulfur dioxide?

Chemistry

July 13, 2014

Question

pls my question sir how can we find sulphideoxide in volcanic.? pls

aminu m - Nigeria (25109)

Answer

Sulfur dioxide has a strong odor similar to rotten eggs. There are detectors available to detect slight amounts of sulfur dioxide in the air. These can be used to tell how much is in the air near a volcano.

Note that sulfur dioxide is different than hydrogen sulfide, although both have a strong odor.

Has video of spirit walking in her bedroom

Senses

July 13, 2014

Question

my name is judy, if theres any question of a live spirit I have one on video walking from my wall into the bedroom, and no it isn't a person, its a spirit and you can see that, ive seen spirits before, not often, I also predicted a couple of things that came true, Im not sure if it is a gift or a curse but I know im different than others, I saw a spirit, a beautiful woman walking past one of the blds that I live near , I asked if anyone was killed there, I was told a woman was killed by a man that was infacuated with her, he killed her when her husband went to work, I described her and they said that's what she looked like,i feel alone with this and scared to tell anyone , that they would think I was crazy, so I keep it to myself, I saw your sight and saw I could right a message , I had the video of the spirit freeze framed and enhanced

judy - USA (25110)

Answer

Thanks for sharing your experiences. Many people can see into the future and past, but not too many have actually communicated with spirits. It probably is a similar talent or sense.

People who have not had such experiences might say others were crazy. Others just keep to themselves.

I don't know what reaction you would get if you put your video on YouTube.

Calculate deflection of charge

Physics

July 10, 2014

Question

I wanted to know the method to calculate the deflection of a charge when it enters a magnetic field with a velocity v.

Mousami - India (25104)

Answer

The equation for the force on the charged particle is:

F = qvB, where F is the sideways force, q is the charge, v is the velocity, and B is the magnetic field strength.

Create sound for homing pigeons

Physics

July 10, 2014

Question

I would like to create a 5 hz sound wave of (maybe high strength) as a sound beacon for pigeons to home in on from say 40 miles away. As you must be aware this would be inaudible to humans but quite easy for pigeons to pick up. Does this sound possible to yourselves, any advice would be gratefully received. Pigeon losses for the last 18 months have been high across uk and I believe mobile masts are contributing, 4g is being rolled out now at a higher strength than than 3g or 2g and anything that could help the birds navigate would be a bonus.Martin

martin - UK (25106)

Answer

Homing pigeons seem to use Sun orientation and the Earth's magnetic fields as primary ways to navigate. But also studies indicate they use low frequency infrasound to help navigation.

The BBC News article Racing pigeon losses baffle fanciers gives some reasons for losses of pigeons.

There are some signal generators that could be used, but 5 Hz may be tough to attain. I can't suggest any specific generator to do the job.

Best wishes with finding out the source of the problem.

Static electricity on wet skin

Physics

July 9, 2014

Question

Dear, your article entitled "Materials that Cause Static Electricity" is very useful. I want to know that what would be the charge on normal and wet human skin? How wettability or dryness get affects the skin charge?

Basant - India (25100)

Answer

Water or wetness can reduce the effect of static electricity. A good example is how dry hair can get charged when being combed. But if the hair is wet or oily, the charges are not effective.

Since there are so many variables, there really aren't any numbers on the effect of wetness on the skin. However, it would be a good experiment to test and measure the difference in static electricity on dry and wet skin.

Constellations and religion

Astronomy

July 9, 2014

Question

School for Champions; I do not know if you have any religious beliefs or not. I am a Christian who is interested in astronomy from a more Biblical point of view.

I was born and raised up in Kermit, Texas where you can see the stars very clearly due to the reduction of big city lights. I used to climb to the top of our house so I could see the stars better even on the horizon. My mother would call me in because it would be getting so late. I am now an older man entering those so-called golden years with no gold!

I know how to read ancient Hebrew hieroglyphs and I noticed that some of the constellations or asterisms which circle close to the North Star looked like some of these hieroglyphs. I had often wondered why God put both a little dipper and a big dipper up in our night skies? Now I know that most of these constellations are not drawn as God intended them according to man! The northern cross is an obvious Christian emblem but is dismissed by the non-believers as just a pattern by luck.

Google, Aquilla Fleetwood, Night Signs. Click on to any site to see these constellations as God intended them. They are pointing us to Christ in ancient Hebrew hieroglyphic word picture form. Google, Jeff Benner, the North Star, for his amazing information. Google, Dr. Frank T. Seekins, Hebrew Word Pictures, for his information about this ancient Hebrew hieroglyphic writings and how Christ is embedded within it.

Indeed, the stars are for signs and the heavens declare the glory of God. Thanks, Aquilla (little eagle)

Aquilla - USA (25101)

Answer

You are fortunate to be in an area to be able to view the stars at night without the glare from city lights.

Although the Bible states that God created the heavens and the earth. I don't believe there area any Bible phrases indicating the constellations were meant to represent anything, except that man could view the stars and see they are the work of His hands.

Since the stars have been in motion and change their position with respect to the earth, many constellations have changed positions and shape over the years. The symbolism of a constellation may be a result of man's faith.

Wants to write a memoir

Writing

July 2, 2014

Question

I want to write a book about my life story and my thoughts and feelings about everything in it. I think it could make very interesting reading if I do it well. Getting started, putting it together and making it easy to read seems difficult along with getting it published

I'm not sure where to start although I have lots of ideas. I wondered if you could give me some guidance?

Thanks very much

Kind regards

Michelle

Michelle - UK (25077)

Answer

Many writers start on their memoirs by putting entries in a journal or writing a blog. From that material, you can re-organize it into a book.

Also, look over some successful memoirs for ideas on look and feel.

Although a memoir is nonfiction, you can get some ideas from Succeed in Writing Fiction.

Since getting a book published can be difficult, you can try Self-Publishing, once you have completed your manuscript.

Finally, look for writing or critique groups in your area. It is good to get together with other writers for support and ideas. There are also such groups via Facebook, but local ones are always better.

Best wishes for success with your book.

PS: Start now!

can't get into my Amazon account

Publishing

July 2, 2014

Question

I can't get into my account again. Your on line info is messed up?

Bob - USA (25078)

Answer

Although you can use Amazon Advantage to sell books you have in stock, it is better to do future publishing through their CreateSpace program.

However, you should be able to log into your account from Advantage. If you can't log in or forgot your password, there is an option to reset the password.

Other than that, you can try to contact Amazon to see what the problem is. Best wishes in getting this problem resolved.
