Question

Hi School for Champions,

I’m a 2nd year marketing student from University of Pittsburgh and I was tasked to collect e-commerce marketing resources for our class when I came across your page - http://www.school-for-champions.com/ecommerce/resources.htm#.Wi8_qUqWbIV. I just wanted to say thank you for setting up this page!

We do have a library but I was thinking of sourcing other resources from other school libraries and business pages too. And your page was excellent! I bookmarked the link to "How to Start Your Own eCommerce Website
", it was really helpful.

Also, do you still update your list of resources? I found some resources that I think might be worth the add to your list, I hope you can check out these awesome materials:

1. https://www.oberlo.com/ebooks/starting-ecommerce - A guide that explains everything you need to know about starting your first e-commerce store.

2.https://www.shopify.com/guides - A collection of e-commerce guides from Shopify that tackles everything and anything about electronic commerce.

3. https://www.wpkube.com/woocommerce-tutorial-everything-need-launch-store/ - A WooCommerce Tutorial that teaches you Everything you need to launch a store using Wordpress.

Those were really helpful to my task and a must have for students and aspiring entrepreneurs who want to learn more about e-commerce.

Hope this helps, I hope you have a great day!

Regards,

Avery - USA (28352)

Answer

Thanks for the resources. I added the links to the eCommerce Resources and Entrepreneurship Resources pages.

Best wishes for success in your marketing classes.

AnimalHealth

December 6, 2017

Question

Hello there,

I am the author of an interview blog called "How I Got Into Veterinary School".

I was wondering if my blog could be included in your "animal health resources" page?

The focus is on interviewing veterinarians and vet students on how they go in. (because competition is so high)

Please let me know.

Thank you,

Diana - USA (28348)

Keeping static electricity in a material

Static Electricity

November 29, 2017

Question

I want to put a static charge in a material and keep it there. I am guessing a battery with uninsulated wire coil perhaps. Any idea?

Jason - USA (28341)

Answer

The static charge typically stays on the surface of a nonconducting material. However, in time the charges will dissipate into the air.
An electroscope can often hold charges for a while. See Electrostatic Induction.

You really can't create static electricity with a battery.

How do I know if my third eye is open?

Senses

November 29, 2017

Question

How do I know if my third eye is open?

Magz - USA (28342)

Answer

The third eye is a concept of an invisible eye which provides perception beyond ordinary sight. It can also be called the mind's eye.

If you are able to have internal perception of things, you may have an active third eye. Some people, can still see colors with their natural two eyes closed. This may be a case of their third eye being "open".

Writing is putting words and sentences on paper or on the computer word processor. Dictation is the method of verbally recording words and thoughts. There are software applications that will convert what you dictate into material in the word processor. See Writing by Dictation for more information.

How does generator output 60 Hz?

Physics

November 26, 2017

Question

In a hyydroelectric plant rushing water turns a generator, which induces an electric current. How does this get to be 60hz?

Jim - USA (28334)

Answer

The generator is set to rotate at a certain rate. Multiplying the revolutions per minute times the number of poles in the generator and dividing by 120 will give the AC frequency.

For example: 3600 rpm times 2 poles divided by 120 = 60 Hz.

Concerning Mossbauer effect

Physics

November 22, 2017

Question

Just a small comment, possibly a correction. You state that in order to observe a red shift one must have the light source at high velocity.

However with Mossbauer gamma rays the Doppler shift is observable with a few mm/s velocity on the source.

Owen - UK (28333)

Answer

Thanks for pointing that out to me. I'm in the process of adding material on Mossbauer spectroscopy, including the Doppler shift at very low speeds.
