How is listening important to a student?

Knowledge

September 3, 2015

Question

Will it help the other students to gain knowledge through their support? Give simple reason to support your answer.

- India (26355)

Answer

Students gain knowledge through reading, observing, and listening to what is said. Those are the ways information is communicated to the student.

Hotel manager called his boss about complaint

TQM

September 2, 2015

Question

I stayed at a hotel that I felt was dirty, and during there food service a customer cut his had and they just wiped it up with a napkin. this was done right were they served hot eggs. it took them over a hour to clean but at no time did they stop food service. I complained about this and others things going on. The hotel called my employer and talked to a co worker that just happen to be staying at the same place. I paid out of my own money to stay here not under my employer name. They said to my employer I made a person cry and caused issues. All I did was say I was reporting the way the handled blood. Can they call my employer and talk to other customers about me if they were not even evolved.

ken - USA (26351)

Answer

What the hotel management did was highly improper and even could even warrant legal action from you. However, the big thing to do is to rectify things with your employer, such that you don't seem like a trouble-maker.

If the hotel is part of a chain, it might be worthwhile to write a letter to the chain headquarters, stating you were mistreated.

Did your co-worker have any complaints about the hotel? If not, it is better to just make sure things are OK at work. Even apologizing to your boss could defuse matters. (Your job is more important than the complaints).

Needless to say, you can recommend to others that they not stay at that hotel.

How is going to the beach scientific?

Physics

August 30, 2015

Question

Hello my teacher assigned me to do an essay on how going to the beach is scientific it's due tommorow is there any way u can describe every detail
Thank you love

Andrea - USA (26346)

Answer

Going to the beach allows you to observe the way the waves come and and break on the beach. It also shows how the water can move the sand around. Another scientific area concerns the various life-forms in the water and on the beach.

The big thing is that you can be curious and make observations, which is what science is about.

Examination problem

Algebra

August 27, 2015

Question

Mawuli scored 30% of the total marks in an examination and failed by 10 marks. However, Selasie who also wrote the same examination scored 40% of the total marks and got 15 marks more than the passing marks. Calculate
i) the total marks; and
ii) the passing marks in the examination.

Adu - Ghana (26341)

Answer

That is not an easy Algebra problem to solve. Let T = total marks and X = passing grade.

Mawuli scored 0.3T = X - 10
Selasi scored 0.4T = X + 15

Subtract to get 0.1T = 25 such that T = 250 total marks.
0.3(250) = X - 10, so X = 85.
Likewise 0.4(250) = x + 15 and X = 85, which is the passing grade.

Reaching for a goal that seems impossible

Life

August 26, 2015

Question

how do one reach for a goal that seems impossible?

Abiola - Nigeria (26334)

Answer

When you set a goal to get or achieve something difficult, it is important to consider what is required to achieve that goal. You can then break the goal into smaller goals that you can achieve on the way to the greater goal.

For example, if you wanted to get an important job, you would have look at the requirements for such a position. You may need a certain education or recommendations. You would also need persistence in your application.

As you go along achieving the smaller goals, you can congratulate yourself in getting closer to your main objective.

Best wishes on achieving your goals.

Confused about the definition of work

Physics

August 26, 2015

Question

I am confused about the mathematical form of work defination w=fd i think that it was wrong becase when we further elaburate it i.e w/d=f so from it we get that force is inversely proportional to displacement and e.g if we are applying force on a wall with our body then the wall will not cover any distance at that time but we are doing work on it and applying force on so why it was not covering any distance .

faraz - Pakistan (26339)

Answer

When you push on a wall, it seems like you are doing work. However, the scientific definition of work requires motion. Work is the force on an object that is resisting motion times the distance it is moved.

For example, when you push on a heavy box, it is being held back by the force of friction. You are not doing any scientific work until you are able to move that box.

Bringing in a freezer from Manila to Australia

Physics

August 25, 2015

Question

Bringing in a freezer from Manila to Australia. Manila uses 220v 60 Hz. Australia is 240v 50 Hz. Will this cause problems?
Thanks

Robin - Australia (26333)

Answer

It probably won't matter. However, the motor may run at a slightly different speed. It is best the check with the manufacturer to verify this.

When a combination of elements is not magnetic

Physics

August 23, 2015

Question

If two or more elements are chemically combined to form a molecule, it is quite possible that the compound is not very magnetic because the orientations of the atoms in the molecule work against each other.
how?

- India (26331)

Answer

Stainless steel is an example of an alloy or chemical combination of steel and chromium. Although steel by itself is magnetic, stainless steel is not because the chromium atoms prevent the iron atoms from aligning to a magnetic field.

What is hysteresis?

Physics

August 23, 2015

Question

EXPLAIN HYSTERESIS

- India (26332)

Answer

Hysteresis is when a ferromagnetic material is magnetized in one direction, it will not relax back to zero magnetization when the imposed magnetizing field is removed. It must be driven back to zero by a field in the opposite direction.

An example is when you magnetize a piece of iron and then remove the magnet, the iron will not relax back to zero magnetization.

What is Ohm's Law?

Physics

August 22, 2015

Question

What is ohm's law?

Satyavir - India (26328)

Answer

Ohm's Law shows the relationship between voltage, current, and resistance in a simple electrical circuit. The easiest form of the equation is: V = IR

See Ohm's Law for Simple Electrical Circuits.

Suggested SQL resource

SQL

August 21, 2015

Question

Dear School for Champions,

My name is George, and I'm the Developer Evangelist at Toptal. Our Toptal Engineering Blog has published a great post called "How to Tune Microsoft SQL Server for Performance," at: http://www.toptal.com/sql-server/how-to-tune-microsoft-sql-server-for-performance and I think it would be of interest to your readers, especially since your community has already published an article related to sql servers and databases.

Is this something you would be interested in sharing on your site? In addition, I would be open to discussing other ways in which our two publications could collaborate. Would you be up for a Skype chat sometime?

Kind Regards,

George - USA (26306)

Answer

Thanks for the suggested resource. I've added a link to the page at SQL Resources>/a>.

Effect of the flow of current

Physics

August 20, 2015

Question

The hypothesis and investigative question (the aim is to determine the effect of the flow of current on the internal resistance of a 1.5v flashlight cell)

Mercy - South Africa (26284)

Answer

How does internal resistance affect the flow of current? The determination would be an experiment to verify Ohm's Law V=IR. Since voltage and resistance are fixed in the flashlight cell, they would determine the current.
