Why does the US use 60Hz AC?

April 20, 2014

Question

1) Why usa use 120volt 60 hertz instead of 50hertz? What is the reason behind this?

lomesh - India (24877)

Answer

The lesson Background of Worldwide AC Voltages and Frequencies explains that most countries originally used 60Hz, but then a major electrical supplier wanted to use 50Hz. Many countries switched over, even though is 50Hz was less efficient. The United States stayed with the more efficient 60Hz.

Cold water is dark but hot water is not

April 19, 2014

Question

What should I do if I am getting dark water? When I run cold water, it happens, but not with hot...?

Zatch - USA (24876)

Answer

Usually dark water means there is sediment or rust in the water. However, if does not come through with the hot water, it may be settling in your hot water heater or changing by dissolving. You probably should check with a local well service company to see what the problem is.

Why is pendulum angle small?

April 16, 2014

Question

i Have two separate questions 1) it is often recommended that the angle of swing of a pendulum be made as small as possible, WHY?
2) will the value of g be affected if the size of bob be varied, WHY?

bright - Nigeria (24871)

Answer

A pendulum will swing properly at larger angles. However, the equations for period and velocity are much simpler if the angle is small. This is to approximate having to deal with the sine of the angle and other factors.

Since gravity affects objects of different mass equally, the pendulum will swing the same with a heavy bob as a light weight bob. However, if the bob is physically large, air resistance may come into effect.

Fiction

Writing about an unjust war

April 15, 2014

Question

I wish to write about an unjust war,an ethnic cleansing, the effects on a people, the re-writing of history to favor the victor, and the subsequent systematic oppressive rule by the government of the day. How do I go about this? I need a good plot/ plan. Please help.

Pascal - Nigeria (24867)

Answer

You have a very ambitious project. It is a historical novel.

First consider and describe your main character or hero of the story. He is living in a country where there is an unjust war. State who are the leaders of this war. They can be the villains or bad people in your story. What is the reason they want war? Greed? Hatred?

Ethnic cleansing or eradicating other groups are events that affect both the soldiers and victims. There are many personal stories that you can include. Likewise for the other events.

My suggestion is that you break things down into small stories that you can weave together at a later time.

For example, you could have a short story about how there had been a war and the hero's side won. They elected a new leader, and everyone seemed happy. But then the new government started making changes and became corrupt and as bad as the previous one. The hero is jailed but escapes and starts the process over by fighting the new villains.

I hope these ideas help. Best wishes for success in your writing.

Education

Teaching an 8-year old

April 13, 2014

Question

I have volunteered to home school my 8 year old nephew for the last 2 months of school. I am a retired teacher,but I do need a guidance to do the best to for this very bright, but troubled boy. I was called to the Christian applications to start the day. This boy must be challenged.

Sincerely,

Bettie - USA (24864)

Answer

It is wonderful that you are helping home school your nephew. Our lessons are more for middle school through college, so they may be too advanced for an 8-year-old. However, many of the topics may help you in teaching the boy.

There are online schools aimed at younger students. However, many charge fees. Check with your local schools for some suggested online resources.

Best wishes in success with your nephew.

Improper ads on website

April 9, 2014

Tami - USA (24854)

Answer

Thanks for letting me know about that. Such ads some to come up randomly and are not appropriate for our site.

Success Stories

Got my life back on track

April 8, 2014

Question

Dear Mr. Kurtus,

It is an honor to write to you. In the year 2000, 2001, I was going through rather tough times. I was 20 years old.

I could have just talked to my family about my problems, they would have supported me, but at that time, I had kept them for myself.

Through your website, I managed to get back on track. At at that moment, I swore myself I would give 10.000F (now about 1500€) to your website.

The moment where I will actually be able to make that donation is nearing. I just wanted to say Thank You.

Your website, at that moment, shaped my life and repaired my sadness.

Please let me know if where I could send those 1.500€? (I will be able to send them in a year or two, but as you notice, I never forget)

All the best,

C. - France (24857)

Answer

I'm glad to hear that the School for Champions material helped you get back on track and helped to improve your life.

Thank you for making the kind offer of sending money. But what would be even better would be to follow our philosophy of giving back by championing a worthy cause or being a champion to someone else in need. Perhaps you could find someone or some organization in your community that could use help of a donation. That would be gratifying to me, too.

Best wishes on a successful life. Let me know how things turn out.

Character

Have good character but can't advance in job

April 7, 2014

Question

I am so positive and confident yet to trustworthy I have not been able to capitalize on my knowledge and experience in my field

Costa - UK (24847)

Answer

Certainly knowledge and experience are important in advancing in your career. Having good attitudes, character, and confidence make a good impression adds to your potential.

In some situations, a supervisors will see a good worker and recommend the person for a promotion. But there are supervisors who won't do that. It is good to let others know of your skills and character.

You also need to examine the chances for growth in your job. Ask yourself what would be the next step for advancement. In some situations, you may have to seek a transfer or a new job.

Keep up with doing good work and having good attitudes. But also make plans for your advancement.

Best wishes in your career growth.

Can everything be separate universes?

April 7, 2014

Question

I have always thought the same thing, atoms and solar systems are extremely similar. And one step further,Galaxies are similar to molecules. My question, is it possible that everything living is a separate universe? Be it a person, animal, vegetable, and God?

- USA (24848)

Answer

A problem with considering galaxies as similar to molecules, it that galaxies usually have billions of stars. There are cases of double stars rotating around each other. This could be similar to a two atom molecule.

There is the Theory of Multiple Universes (Multiverse) that could apply.

Certainly, there are concepts that go beyond what is commonly considered,

Confusiion about electricity

April 3, 2014

Question

I am confused about circuits. However, i hope you will forgive me, and answer what i imagine are some very silly questions.
I am a westminster challenge candidate, working from the ce syllabus this easter. Im very confused about voltage, current, and ampage, and can't find any explanation i understand on the internet.
Is voltage "used up"?
Is current "used up"?
Is their a relationship between the amount of current and the voltage?
If so, What is it?
Do any of these questions have different answers in relation to parallel and series circuits?
If ampage is the measure of current, what's voltage the measure of?

- UK (24838)

Answer

Voltage is like electrical pressure in a wire. It really can't be used up, although if the source of electricity is a battery, it can wear down and the voltage can get smaller.

Current is the flow of electricity through a wire. If there is more resistance in a wire, the current can get smaller.

The relationship between current (I), voltage (V), and resistance (R) is: I = V/R.

Current is measured in amperes or amps, voltage is measured in volts, and resistance is measured in ohms.
