Rolling friction for horse-drawn cart

Physics

August 27, 2014

Question

What will be the frictional force for rolling friction in horse and cart motion. The term for Force of friction,
F = ?R W/r, where r is the radius of 4 wheels.
Now my actual question is the total frictional force is contributed by 4 wheels / or not.
Then will it be total Frictional force= 4 ?R W/r for 4 wheels.

PANKAJ KUMAr - India (25326)

Answer

With such a cart, there probably would be more friction from the axles of the wheels than the rolling friction.

To establish the rolling friction, you need to know the surface on which the wheels are rolling. The total rolling friction would be Fr = mu(R)*W/r. That would probably have to be determined experimentally, since there are so many variables.

Role of training in TQM

TQM

August 26, 2014

Question

1-Discuss the role of training and education in supporting TQM ?
2-Explain the difference between satisfaction and loyalty. why is loyalty more important ?
3-Let explain, why are strategic partnerships and alliances useful to an organization ?

Tem - Cambodia (25321)

Answer

Since there may be confusion or even resistance to implementing TQM in a company, training and education is important. This includes training of management, so that they understand the principles.

Loyalty comes from having good experiences with a product or company and results in repeat business. However, if the customer is not satisfied with a product or service several times, the customer will no longer be loyal and even disgruntled with the company.

Can i use a 110-220v appliance on 240v

Physics

August 23, 2014

Question

can i use a 110-220v appliance on 240v

claude - Australia (25313)

Answer

A 220 volt appliance should be able to work on 240 v. However, you need to make sure they both have the same outlet plugs.

Also, if the frequency is different, the appliance may run at a different speed.

Mini-quiz on antimatter not adequate

Physics

August 22, 2014

Question

Hi.
The Antimatter Mini-Quiz is extremely inadequate and consists of elementary flaws.
First off, three simple multiple-choice questions are not sufficient. Second, there are two basic mistakes:
(Q2) The anti-matter in the container won't combine with the matter. In fact, the electron and positron will be involved in a cosmic dance and then annihilate in a tiny fraction of a second. The same is with the proton and antiproton, and the neutron and antineutron.
(Q2)Energy is neither created nor destroyed; everyone knows that. So a great amount of energy is NOT 'created'; rather, the energy stored in the particles of matter and anti-matter are released with a great force, in the form of gamma rays.
Thankyou!

Rushda - India (25305)

Answer

I am sorry you did not find the three questions in the Mini-quiz sufficient for your needs. I am sure you can purchase a physics textbook with many more questions and answers.

Question 2 did not address the time it takes for the atoms to interact and annihilate. However, I did correct using the word "created" to avoid any misunderstandings.

I updated the Antimatter lesson and its Mini-Quiz to correct any flaws.

Idea for a children's book

Publishing

August 22, 2014

Question

I am a children's writer and I am working on a picture book for grades K-5 which uses magnetism as the storyline and I have a question. I wonder if you might be so kind as to help me out.

The title of the book is Magnetic Magic and young Dena delights the little kids at the pool by performing tricks with magnets. Of course, she doesn't fess up that she's using magnets, she calls it magic. In comes this new kid, Mark, who tells her is not nice to fool the little kids. Dena simply doesn't care. Mark then hands her a map from 1905 and dares her to find the spot. Here's where the declination comes in. Using the NOAA site, I came up with a change of 10° W from 1905 to 2015 on the line that seems to pass through Virginia. Our heroine can't find the treasure using the directions on the map, but eventually she finds the treasure and realizes the directions were wrong. Mark fooled her just like she fooled the little kids. He lets her know that magnetic North has changed over the years. In the end, Dena lets the little kids know that it's magnetism, not magic.

The way I have written the story, the quest takes place in a small town and the kids walk in search of the treasure. I just want to make sure that can happen in such a small place. That is, when she marks her route using a protractor and the 1905 directions, ten degrees over could just be a couple of blocks away, not miles away. Doing the math and plotting in my head and on a map, I believe this will work, but I want to make sure before I submit the manuscript.

I plan to submit the manuscript to Arbordale Publishers. They publish engaging stories that touch on science, but include four pages of hard facts and educational text on the back of the book as well as many pages of more educational text, games, and activities on the book's website. My first book for Arbordale was on the recovery after Mount St. Helens' eruption. The book was named Outstanding Science Trade Book by the National Science Teachers' Association and the Children's Book Council. They will be publishing Sounds of the Savanna, a book about sound as told through a story on prey/predator interactions in the African Savanna, in 2015. I also write educational text for the Smithsonian Science Education Center. I would love to chat with you about this if you have a minute. I will be happy to call you if you let me know the number.

Thank you so much for considering my request.

Sincerely,

Terry Catasus - USA (25309)

Answer

Congratulations on writing another children's book. It looks like you have a good writing background, as well as getting awards.

I got s little confused concerning your story line. I'm guessing that the 1905 map indicates where a treasure is buried, according to the inclination of a compass pointing at the magnetic North Pole. Since that pole moves slightly each year, they would have to calculate the position according to the 2015 position of the pole.

That might be too difficult for 5th graders. Also, it seems to be getting off the theme of properties and experiments with magnets. Perhaps it could be changed to something like finding an old iron mine, using a compass.

Feel free to contact me to talk about your book and stuff.

Using formulas

Physics

August 21, 2014

Question

hi my name is zodwa i've got a problem in understanding physical science especialy on how to put the fomular in some of the question.so plz help coz i want to study pilot by next year.

zodwa - South Africa (25300)

Answer

In various areas of Physical Science, there are formulas or equations to show the relationship between entities. For example, F = ma, states that in some situations, force equals mass times acceleration. Thus, if you know two of the items, you can use Algebra to find the third function.

In many areas of the science, you can understand the ideas without using any formula, but they are often used in problem solving.

Best wishes on becoming a pilot.

Has to swallow in middle of talk

Speaking

August 19, 2014

Question

I have been doing readings in my church once a week for almost 2 years. I have overcome the initial fear of standing at the altar in front of the congregation, I prepare my readings all week and I know it almost by heart, the only problem I have is my saliva, I get the need to swallow in the middle of a sentence than would interrupt the intonation I want to project. If I force myself to continue without swallowing my voice sounds like I am about to cry.
I do not feel nervous or anxious anymore but this problem is causing me a problem.
My question: What to do to control the saliva.
thanks so much,

Sefora - USA (25291)

Answer

I used to have the same problem when I was in school and had to get up in front of the class. I know that it can be disruptive. With more confidence, I overcame the problem.

Do you practice the reading in front of someone, such as a family member or friend? You probably wouldn't have the problem then, and it might help during your "official" reading.

Another thing you might try is to have a glass of water available by the altar. Pause to take a sip at certain points in your reading. This may even add a dramatic effect to the talk.

You might ask your minister if he or she ever has the problem with having to swallow, in order to get some advice on the matter.

Best wishes on giving some great readings to your congregation.

How long to reply to a non-conforming report?

ISO 9000

August 18, 2014

Question

Their was an old statment on how long you could let a non-conforming report lay prior to a response what is it. My thinking was three days prior to a response?

- USA (25281)

Answer

Ideally, the response to a non-conforming report should be immediately. Unless the response would have to be checked over by management, there really is no reason to procrastinate on a matter.

Of course, this also can be defined by company policy.
