If a voltage source is applied to the output of the op-amp (with NO feedback to the input), what happens to the circuit/device? Does the signal just go straight to ground or open circuit? Or does it cause the op-amp to break down because of high current, etc?

Like how did they find out that to times something in a column the second time you times you have to put a sero and then add the 2 answers together or how did they find out that pie is 3.14 or how did they find out how to make fractions into decimals and percentages vica versa..

I'm writing a story about Quartz and in order for me to do that, I need to know where are they found. My brother said that they are found somewhere in hot springs, but I don't know what that is. Maybe you guys can answer that too?

Hello Canadians :)
I currently live in Brazil and I am a math professor teaching Linear Algebra and I also can teach chemistry. I speak many languages including French so that may be a benefit to teach in Canada. My salary is very low here. I get only about $1000 every month and as a Professor I believe I need more than that.
I was wondering what the average salary is there in Canada for Professors teaching in Universities or Highschools.
I'd also like to move to Canada to teach but how am I to go about this? Would I need a visa?.. That would cost I'm assuming around $3000 but can I get a loan?
I just would really appreciate if someone were to suggest the first step I should take in wanting to work in Canada as a Professor... I don't have knowledge on how to do this.
Please any suggestions? Thank You!

A certain long-distance carrier provides service between Podunk and Nowheresville. If x represents the number of minutes for the call, where x>0, then the function f defined by

f(x)=.40[[x]]+.75

gives the total cost of the call in dollars. Find the cost for a 5.5 min call.

For example, square root of 3 and the square root of 5 yields an irrational number. If not, how would you prove that all numbers that are not perfect squares be irrational?

I have noticed that any kind of bread - bagels, buns, rolls, loaves - when kept in a plastic bag, in the refrigerator, dries out on the bottom, while the top gets soggy. What's up with this water migration? It doesn't happen to bread kept in plastic bags at room temperature...

This might sound like a stupid question, but if i determine a longitude and latitude off a map today, would it be the same as one an explorer might have in 1738? The same system was used, wasn't it?

Question 1 .The standard procedure for dividing by a fraction is to turn upside down and multiply.how would you justify this rule to a child?What higher level of mathematics informs your understanding of the procedure?

Question 2.Tiles in the shape of regular hexagons can be used to cover any plane surface,but those in the form of regular pentagons cannot ,by themselves,be used to tiling an area.How might a teacher use this activity to enable children to deduce some facts about angles in polygons?How might examples from art or architecture be included to enhance study of the topic

So, I live in Cali. Usually, during the Summer, the sun is out and about.. and everyone stays half naked because it's so dang hot. However, lately, it's only been about 60 degrees. I find it incredibly odd that no one ELSE finds this incredibly odd. Are you kidding me?! I've lived here for 10 years... and I want to know what happened to my 110 degree days!!!! :( CAN ANYONE GIVE AN EXPLANATION?!?!?!?!??!?!? PLEASE?!

I'm looking for a set of references and/or websites that could give me a basic course in "astrophysics for dummies". I find the topic fascinating, and am currently working on a sci fi novel and would like to do some serious research first.

I've noticed that the Dummies series of books publishes a book called "Astronomy for Dummies" but I'd like to make sure that this really isn't just "Stargazing for Dummies" or some really primitive treatise on the subject.
