Science & Mathematics - 3 November 2007

I am switching my major to geology, I find it very interesting. I want to focus in hydrogeology and watershed science. What kind of jobs will I be able to get with this degree?

Those of you who feel evolution explains the origin of DNA on the planet. Tell me one thing that you KNOW is true about evolution. A fact that will not change, that has not changed. Just curious. (can i check with you in 20 years to see if you are right?)

I've learned in my Medical Terminology class that it's considered part of the digestive system even though it has no function? Why is that? I know researchers have been trying to find out for years what purpose does it serves but if we can do every thing else why can't we find this out. Well any ways do you want to guess? Any theories? Any guesses?

...of the following reactions.

1.) An aqueous solution of sodium hydroxide reacts with an aqueous solution of hydrochloric acid, yielding water and sodium chloride.

2.) An aqueous solution of sodium hydroxide reacts with an aqueous solution of ammonium chloride, yielding aqueous ammonia (NH3), water, and sodium chloride.

3.) An aqueous solution of hydrochloric acid reacts with aqueous ammonia, NH3, yielding aqueous ammonium chloride.

Can someone please help me with this?

i thought that NaHC2O4 in water would produce NaOH (a strong base) and also H2C2O4 (oxalic acid, weak acid) therefore the solution would be basic, but the back of the book says it should be acidic. Why is that? Am i wrong or the book is wrong?

Starting with equal moles of each solute, predict the direction in which the following reaction will proceed.
H3PO4(aq) + HCO3-(aq) = H2PO4-(aq) + H2CO3(aq)

a. to the right
b. to the left
c. no net reaction

If you know, please answer

thanks!

I love meat but I don't think we have to eat meat.

Here is why:

1. Do most people even have what it takes to kill an animal themselves? No. I know I don't.

2. Do we eat meat raw? No. We cook it.

3. When we see an animal alive and well do we look at that as dinner? No. We cook it and use seasonings and sauces.



I do like meat but I don't think we are really omnivores. I think we developed over time to be able to eat meat.

Maybe the Vegetarians are on to something.

I have a set of N points in a 2 (or 3) dimensional space. How do I find the point P for which the sum of distances to the N points is minimal?
Is there a known name for this problem?
Thanks.

We have to build an arch bridge for a geometry class, with abutments, voussoirs, and a keystone.

http://www.makingthemodernworld.org.uk/learning_modules/maths/02.TU.03/illustrations/02.IL.24.gif

How big should the measurments of each part be? How many voussoirs should there be?

Would it work if we had 10 voussoirs total? The measurments of each voussoir as:

3 in and 4 in (nonparallel sides)
3 in and 3 in (parallel sides)
75 degrees (bottom base angles)
105 degrees (top base angles)

If that works, what should the keystone measures be? And the abutments?

Thanks so much!
