Finding force of attraction
March 4, 2014
A body of mass 25gm was placed at a distance of 15cm from another body of mass 42gm, find the force of attraction
Kingsley - Nigeria (24571)
Apply the equation F = GMm/R^2 shown in Gravitational Force Between Two Objects, where G = 6.674*10^?11 N-m^2/kg^2, M = 25 gm, m = 42 gm and R = 15 cm.
You must convert gm to kg and cm to m before doing the calculations.
Are there a lot of galaxies?
March 2, 2014
Is in universe there are lot of galaxies?
shital - India (24569)
In the Universe, there are billions of galaxies, and within each galaxy, there are billions of stars.
It is hard to imagine such large numbers.
Seeking job as chemistry teacher
March 1, 2014
I HUMBLY APPLY FOR THE POSITION OF A CHEMISTRY TEACHER IN YOUR REPUTABLE SCHOOL.
I PLEDGE TO DISCHARGE MY DUTIES EFFECTIVELY AND TO ABIDE BY THE RULES AND REGULATION GUIDING THE PROFESSION AND THE SCHOOL.
I HAVE MSc IN BIOCHEMISTRY AND A PGDE WITH THREE YEARS TEACHING EXPERIENCE.
THANKS FOR YOUR COOPERATION.
AFEEZ - Nigeria (24566)
The School for Champions is an online educational resource. I am sorry, but we are not hiring chemistry teachers.
You seem to have good qualifications for employment in chemistry. I am sure there are companies or schools in your area seeking people in biochemistry. It is always best to start looking for work near home and then work your way to other locations.
Do some research on companies doing chemical and biochemical work to see what opportunities there are. Also, you might check your college to see if they have any listings for teachers in other schools.
I hope these ideas help. Best wishes in finding a new job and in advancing in your career.

Can I use AC transformer to convert DC to AC
February 28, 2014
can we use th ac transformer structure for a 7v dc input nd higher ac output??
arpan - India (24562)
A Power Inverter us used to convert DC to AC. Some people use them in their automobiles to power small electronic devices requiring AC from the DC battery.
Although inverting 7 V DC is possible, there may not be enough current.
Efficiency of a machine at 100%
February 28, 2014
why is the efficiency of a machine is 100 percentage?
jamiu - Nigeria (24565)
The only time the efficiency of a machine is 100 percent is if there are no losses due to friction, heat, or other forms of energy. However, all machines have some losses and thus have efficiency less that 100%.
See Efficiency of Machines for more information.
Resources on clean water
February 27, 2014
My name is Lynn Taylor, a member of the Berkey Filters team. In my current role I conduct research and create informative articles relevant to the cleanliness of water. This includes everything from water pollution, water purification, and the overall benefits of life's most valuable commodity, water. When conducting my research I am sure to use credible and and reliable resources to support any and all topics discussed within the article. As a huge advocate for keeping the world's waters as clean as possible, I do my best to help keep as many people informed as I can. After exploring your page http://schoolforchampions.com/health/resources.htm I feel that my article which can be found at http://www.berkeyfilters.com/articles/the-many-methods-of-water-purification/ would be a wonderful addition to your resources. On your page, I was able to find an great deal of relevant and quality information and would like to help add to it. I hope you will add my article to your page as it would help to educate more and more people.
Thank you for doing your part and creating such great page.

Find the CG of combined figure
February 24, 2014
how can you find cg of a combined figure with triangle rectangle and a semicircle
collins - Kenya (24554)
Although there are geometric methods to find the center of gravity of various shapes, they can be quite complex.
The most common method to find the CG of an item is hang it from several points on its surface along with a plumb line or weighted string. The intersection of the plumb lines would be the CG.
What is a sound wave?

What is a sound wave
Wally - South Africa (24552)
See Overview of Sound Waves for information.
Moved from zero to hero
February 22, 2014
i would like to thank you school-for-champions because of good marks you gave me on my physical science exams. i have A pass on this subject only because of your web. Truly speaking! i didn't know anything related to physical science but now ,because of you, i moved from ZERO to HERO!!! Really, lot's of thanks are deserved by you, THANK YOOOUU! keep it up guys!!!

Is pendulum relation a function?
February 21, 2014
Hi I have a question:
Is this relation a function?
- Canada (24547)
T = 2pi*SQRT(L/g) is the equation for the period of a simple pendulum. It is not considered a function.
February 20, 2014
Just wondering if anyone read my previous email in adding www.safemart.com to your list of Security Resources. I think it is a relevant and helpful addition. Please email me as to the status of this request.

Values for coefficient of static friction
February 19, 2014
can you please lay more emphasis on the coefficient of static friction?
Ezemonye - Nigeria (24539)
There is an extensive list at Coefficient of Friction Values for Clean Surfaces.
Otherwise, the value can be dome experimentally.
Slope in change of state
February 19, 2014
What is the Slope of graph between temperature and heat in change of state? Answer quckly
Sushant - Nepal (24541)
The slope of temperature/heat in change of state depends on the material.
