Wants replacement pots
April 22, 2020
I bought my Prudential waterless cookware in 1965 with a lifetime warranty. I ruined 2 of pots on a glass top stove. How can I find this company to request replacements. The other pieces still look brand new. yes, I have put the large fry pan in the oven no hotter than 350. then i oiled the handles with mineral oil and they still look great! Thank you for your help.

It is great that your cookware has lasted so long, and it is too bad you ruin 2 pots.
Apparently, EKCO Prudential is out of business. However, I have seen many pots for sale on eBay and similar sites. Do a Google search on the brand name, and perhaps you can find some replacements.
Best wishes for success in your cooking.

Choosing foods to eat
April 13, 2020
Good day, I am from South Africa, I was looking at the intermittent fasting diet but there is foods on that I don't know at all, can I choose the green veggies that I know for instance broccoli, cauliflower, baby marrows etc. and the salmon to tuna.
Vicki - South Africa (29434)
It is the most convenient to choose the foods and vegetables that your are familiar with and are ready available. However, you should use some caution in eating tuna because some can contain a small amount of mercury, which is unhealthful.
Best wishes on a good, healthy diet.
Mass and gravity
April 9, 2020
The mass of the earth is listed in many places on the internet as 81 times the mass of the moon.
The gravity on the moon is generally agreed to be one sixth of that on the earth. How do you reconcile these figures?
Is the relationship linear?
Benjamin Hills - USA (29427)
That is a dilly of a problem. Gravity on the Moon relates to both the ratio of the masses and the square of the ratio of the radius of the Moon and Earth.
I put together a new page that goes through an explanation of how the gravity on the Moon is 1/6 of on the Earth. See:
Gravity on Earth versus on Moon.
I hope that clarifies things.
Building a face mask
April 8, 2020
Hi im building my own face mask out of hepa filter and finely grounded activated carbon charcoal powder grounded in a coffee filter but how do i electro-charge the mask? That's the last thing I'm trying to figure out then i can be done. Please help and thanks
Riley - USA (29425)
That is a clever idea to try to static charge the face mask to attract and filter particles.
One problem is that the static charges would probably dissipate into the air. Also, do you want virus particles to collect on the face mask?
I think a bigger concern is air leaking around the edges where the mask fits on your face.
Let me know how you progress on your idea.
Gets static shocks all the time
April 7, 2020
Every thing I wear I get shocked while opening doors like my car, home, store etc. I have tried everything. Please help.
Melinda - USA (29422)
Some people seem more prone to static electricity shocks than others. One solution is touching metal handles with a key or ring before opening.
See Reducing or Preventing Static Electricity Shocks for details and possible solutions.
I hope helps in reducing that annoying problem.

I have had prudential waterless cookware since 1970. Love it. Can I put the frying pan in the oven or will the handles be ruined?
Diana - USA (29402)
It is great that your cookware has lasted so long. However, putting the frying pan in the over could possibly damage the handles. It would be better to use some other type of pan.

Handle broke on waterless pan
March 24, 2020
A handle broke on one of my pans and I need to know how to get another one.
Bob - USA (29393)
Check the list on Waterless Cookware Companies for your brand and replacement. Also look at the Feedback letters to find a possible solution.
Good luck in getting the handle replaced.

Karen here from Autism Parenting Magazine, the leading magazine for parents of autistic children as well as professionals seeking to work with children on the spectrum.
I am just reaching out because of your piece here: https://school-for-champions.com/mentalhealth/resources.htm
Now the reason it caught my eye is that I recently put together an updated post and guide on the best vitamins and supplements for autism which I thought would make a very worthy addition into your piece.
If you'd like to check it out, the link is below:
If it's worth it, I was wondering if you might consider dropping my link into your wonderful piece?
I would be super grateful if you might consider it or do you want to do some collaboration?

Special exponent cases
February 24, 2020
Thank you sir for the opportunity to ask a question.my question goes like this:
we talk of a^m ×b^m = (axb)^m , and a^m × a^n = a^(mn); But if we have:
Q1. a^m × b^n = ??, And
Q2. 16a^5 ÷ 4a^2 = ???
Please help on what to do in these cases since no law backs them.
Kwo - Cameroon (29367)
Often it is handy to write the problem with small numbers to understand the rule.
Note that a^m × a^n is not = a^(mn). Consider a^2 x a^3 = aa x aaa = a^5 = a^(2+3) or a^(m+n)
Q1: Even using small numbers, you can see the a^m x b^n cannot be simplified.
Q2: 16a^5 ÷ 4a^2 = (4^2*a^5)/(4a^2) = 4a^(5 - 2) = 4a^3
I hope that helps. Best wishes for success in Algebra.
Type of speech

what type of speech is this?
theresa mae - philippines (29360)
It was a persuasive speech. He was telling the students not to give in or give up in what they attempt.
Coefficient of friction on an incline
February 17, 2020
When finding the coefficient of friction on an incline, is it helpful to go with the lowest value or should I take the average? Or both?
Hannah - USA (29361)
First there is static friction on an incline, holding back the object. Then once the object slides, there is sliding friction, which as a lower coefficient of friction. Typically, you only state the sliding coefficient.
