Suggested resource

Entrepreneurship

February 15, 2017

Question

Hi Ron,

I just found your website! In particular, I enjoyed browsing through your Entrepreneurship resources.

It's great that there is also some information about starting an online store. Do you think it would be helpful to also include other ecommerce providers than just Shopify? We have a ranking table of various providers on our site. If you believe that this could be useful to your readers feel free to add it to the list.

Best of luck with your project!

Kind regards,

Robert - USA (27881)

Answer

Thanks for the suggested resource. I added it to Entrepreneurship Resources and ECommerce Resources.

Best wishes for success in your endeavors.

How do electromagnets work in railway signals?

Physics

February 14, 2017

Question

How electromagnet works in railway signals?

Harsh - India (27879)

Answer

Railway signals can be flashing lights or a moving barrier.

An electromagnet could be used as a solenoid to turn on or turn off the railway signals.

The barrier is usually moved by an electric motor.

I don't understand Astronomy at all

Astronomy

February 14, 2017

Question

I don't understand Astronomy at all. I don't enjoy studying about a whole new world that I've never visited. Is their an easy way to understand Triangulation, Radio telescopes?

Jawerriya - Canada (27880)

Answer

It can be interesting to look into the night sky and see all the numerous stars in the sky, as well as their movement throughout the year. Some people like to learn the constellations and arrangement of the stars.

However, Astronomy can delve deeper to find out what the planets and stars are made of. It is a scientific study that some people are interested in and others are not.

Triangulation is a method to determine distance using trigonometry. In Astronomy, it is useful to approximate distance of far-off objects.

A radio telescope uses radio waves instead of light ways to detect distant objects in space. In some situations, it works better than visible light.

Although teachers can often learning many facts without making the subject interesting, it is good to find things about the subject you like.

Best wishes for success in your studies.

Unmarked saucepan needs fixing

Health

February 10, 2017

Question

I have a double boiler saucepan 2-3 qt with no brand mark. It's heavy and appears to be waterless. There is a circle on inside bottom of pan. The lid is Saladmaster and fits well. Did Saladmaster make a pan not branded??
Also missing handles on both pieces and the rectangular metal stub that handle fits onto is 1/2" x 3/4". The handle from the marked Saladmaster pan that came with this unmarked one fits on either pan. Need to know a possible brand so I can order handles to replace them.

Diane - USA (27873)

Answer

It is unlikely that Saladmaster would not have a brand mark on their cookware.

You can try to order parts from Saladmaster Parts. Personally, I would check into getting a new saucepan instead of trying to fix the old one.

Water pressure when stones added to a pool

Physics

February 9, 2017

Question

Ron, Thanks for your article. what happens to water pressure if some of the water is removed and replaced by stones. In a pool. I think the water pressure at bottom of pool is reduced.

Kieran - UK (27870)

Answer

Water pressure is caused by the weight of the water above the point of measurement. If the pressure is measured in grams per square cm, it would be the weight of the column of water 1 square cm times the height.

This would be true for water pressure at the top of the stones. Since the distance to the surface is reduced, the water pressure would be less at that point than at the bottom with no stones.

Question

how can i become a champion

Saviour - Zambia (27858)

Just wanting to become a champion is a good start.

Consider areas that you have great interest in and are good at. Then seek to do your best in those areas. This will build your confidence.

While you are seeking to achieve your goals, use your skills to help others achieve their goals. This will make you a champion to them.

Continue to study and to excel. I know you will succeed and become a champion.

Have article on speaking

Speaking

February 6, 2017

Question

Hello,

Love the website, keep up the good work.

I enjoyed reading your article about Public Speaking below:

http://www.school-for-champions.com/speaking/resources.htm

I've written a 5,000-word article on becoming a better public speaker on my blog that builds on that post in more detail. In addition, I also filmed a 40-minute in-depth complimentary video on public speaking to go with it.

I believe it will be relevant to your audience, let me know if you would like me to send it to you.


Cheers,

Ian

How does pressure affect a liquid?

Physics

February 6, 2017

Question

Give 3 ways on how pressure acts on liquid

Adu - Ghana (27860)

Answer

Pressure acts on a liquid in all directions. Pressure can also increase the temperature. Pressure only decreases the volume a small amount, if at all. Likewise, the temperature that the liquid changes to a solid is only slightly affected by pressure.

Placing electromagnet inside another electromagnet

Physics

February 5, 2017

Question

I have a new found curiosity for electromagnets. I'm not a scientist or even a student... just curious. What would happen if your electromagnet core contained another electromagnet?

Ron - USA (27857)

Answer

If the core is movable, you would have a solenoid of sorts. (See Solenoids are Electromagnetic Devices).

Instead of having a movable iron core or magnet core, you would place an electromagnet there. This would allow movement of the core to be finely tuned. However, I don't think I've even seen such a configuration.

Amount of liquid in a certain vessel

Experiments

February 1, 2017

Question

Hello sir my question is that there is a non uniform vessel which volume is known and there are two valves on it: inlet and outlet. We fill some it with some liquid. Then how do we know how much liquid we filled in with?

praveen - India (27850)

Answer

The inlet and outlet positions will determine how much liquid can be put in the vessel, according to the height of the lowest valve.

You could fill the vessel until the liquid starts coming out of the output valve. Then pour the liquid into a regular shaped container to measure the volume of the liquid.

It seems like extra work, but that is the best way to do it.

Work hard but getting poor grades

Grades

February 1, 2017

Question

I always work hard in school but I have a d- in math an f in science and a c- in geography I'm in 6th grade and I work a hard a a do in ela and I have an A+ in the why am I having a harder time in the rest of the claess

abby - USA (27853)

Answer

The fact that you are working hard and scored high in the English Language Arts (ELA) test means that you have the potential of being a top student. However, you must be doing something wrong to get the low grades.

Are you doing your homework? Are you good in taking tests? Some students know the material but are not good in taking tests. See Be Good at Taking Tests for some hints.

Also, you might ask your teachers if they can give you some pointers on how you can do better in their classes. It is not easy to do that, but you might get some good pointers. Also, it shows the teacher that you want to get better grades.

Look at some of the other Good Grades lessons for other ways to improve.

Best wishes on getting top grades. I know you can do it!
