Difference between gravity and gravitation

Physics

February 27, 2015

Question

What is the difference between force of gravity and universal gravitational constant?

CLEOPHAS - Kenya (25796)

Answer

Gravity is a force pulling objects toward the Earth. It is an approximation of gravitation, which is the attraction between objects.

In the Cavendish Experiment, the gravitational force between two masses is measured to find the constant G.

See Gravity and Gravitation for more information on those subjects.

Neighbor blasts loud music non-stop

Physics

February 25, 2015

Question

I have this neighbor kid, who non stop for 10 months now has been pounding his powerful sound system thru my house. this has caused me health problems and I had to move. the police have been in their house and told me they have gigantic speakers angled at my place, only a few feet between homes. the kid turns the sound off and pounds the treble, bass and with low frequency cd's he's downloaded or whatever crap and continuously cranks it. do have any advice what to do in this situation. the police seem to helpless.

- Canada (25792)

Answer

I'm sorry to hear that you've had such a hassle with the neighbor's loud noise. Although it may not change things, but it is worth talking to him and his parents about the loud noise. Sometimes people don't realize such loud noise affects other people.

I find it surprising that the police can't do anything about it. I know that in most communities, excessive noise from a barking dog can result in a fine. I would assume there is some law in your community about excessive noise from music. Perhaps the police don't want to bother. It would be worthwhile checking with city representatives about laws on excessive noise.

Another route is to talk to a lawyer to see if any action can be taken to stop the noise--like a lawsuit.

So, first try talking to the people, then check to see what laws are being broken, and finally as a last resort look into some legal action.

Best wished on solving your problem, There is no reason to have someone disrupt your life with excessive noise.

Is polluted water a suspension or solution?

Chemistry

February 24, 2015

Question

IS POLLUTED WATER A COLLOID SUSPENSION OR A SOLUTION I NEED TO KNOW I HAVE A TEST SOON PLEASE HELP

nekopockygurl - Japan (25787)

Answer

The causes of polluted water can be complex.

Usually polluted water is a mixture of dirty material. Some chemicals can dissolve in the water to make the pollution a solution. Materials in the water that could create a colloid suspension would consist of particles that do not settle.

Doing a free online course in public speaking

Speaking

February 24, 2015

Question

I am interesting in doing a free online course in public speaking.

juliet - Barbados (25789)

Answer

You really can't learn to speak well through an online course. Public speaking requires practice in front of a live audience.

A good way to learn public speaking is through Toastmasters. Check the Bridgeton Barbados Toastmaster website to get some information. There is no obligation for attending a meeting to see what it is all about.

I hope that helps you.

Sensing spirits in photos

Senses

February 23, 2015

Question

Hello, I was wondering if a sixth sense would include being able to see spirits in photos. I almost immediately find a ghost or spirit in images. I can send some obvious ones over.

Rebecca - USA (25786)

Answer

The 6th sense is more concerned with sensing future and past events. See Sensing Spirits for information that might be about sensing spirits in photos.

Insulation for ESP casings

Physics

February 21, 2015

Question

Dear Sir;
I want to know if the thermal insulation of ESP casing mandatory.
Will ESP performance get affected for non insulation and how/ why?
Regards

Virendra - India (25776)

Answer

The insulation for electrostatics is not necessarily thermal insulation. Rather is is electrical insulation. That means it is made of nonconducting materials.

If items are not insulated, there is the possibility of electrical conduction, which you may not want.

Why aren't humana as tall as plants?

School for Champions

February 19, 2015

Question

why is it that human beings are not as tall as plants and when and how can human beings reproduce asexually

Valentine - Nigeria (25774)

What is atmospheric pressure?

Physics

February 18, 2015

Question

what is atmospheric pressure?
how can force change a position?

- India (25771)

Answer

Pressure is force divided by area.

Atmospheric pressure is the weight of a column of air divided by the surface area of the column. For example, kg per square meter.

See Pressure in Fluids for more information.

If a force acting on an object is strong enough to overcome resistance, such as friction, the object will move and accelerate, according to F = ma.

Applications of thunder and lightning

Physics

February 16, 2015

Question

what are the applications of thunder power generation also about lightning

hima bindu - India (25770)

Answer

Thunder is simply the sound that is created from lightning. It has no real application.

Some have tried to harness the power from lightning. A major problem is that lightning strikes are not very predictable.

Finding volume of irregular objects

Experiments

February 11, 2015

Question

i send u greetings.my question is, how is the experiment "finding the volume of an irregular objects "important 1).globally
(2).in Education (3).in the world of work.Thank you.

- Ghana (25761)

Answer

A major purpose in wanting to find the volume of an irregular object is to help determine the material that the object is made of.

For example, if you have an irregular object that is supposed to be 100% gold, you can find its volume and compare its weight with the weight of the same volume of gold. If there was some other material mixed with the gold, the weight would be different, proving that it is not 100% gold.

Knowing this method can be important in education, as well as in business.

Where is TQM used?

TQM

February 11, 2015

Question

I would like to know some of these questions...

For what type of business is it designed?

What does the business need to do to obtain it?

Which businesses had or have this system or prize?

valeria - Mexico (25767)

Answer

TQM can be used for both for profit and non-profit businesses. The idea is to improve the quality of products and services delivered to customers, such that they are satisfied and want to do repeat business. But also by improving the processes, the business will reduce wasteful practices and have better profits.
