Hmm...switching to kelvin opps :biggrin: edit: doesn't matter since its a constant.

A liquid has a maximum density of 0.6 g/cm^3 at 3.7 C. At 11.4C , its density is 0.60888 g/cm^3. What is beta for this liquid over this temperature interval? Answer in units of (C)^-1. Obviously this has to do with the volume expansion so I made the formula deltaV = beta * initial volume *...

A room of volume 68 m^3 contains air having an average molar mass of 36.3 g/mol. If the temperature of the room is raised from 17.2C to 25C, what mass of air will leave the room? Assume that the air pressure in the room is maintained at 43.6 kPa. Answer in units of kg. Been messing around with...

Just wondering you know if the answer is in symbolic form or do you have numbers such as the weight of b?

easy pressure and fluid problems..i swear :) Got some (what I think) are easy pressure and fluid problems. A 23.5 kg woman balances on one heel of a pair of high-heeled shoes.The acceleration of gravity is 9.8 m/s^2 :If the heel is circular with radius 0.225 cm, what pressure does she...

The last I read fermilab and cern ( don't think they are done yet though, don't remember) were both on the hunt for gravitons and so far they have been unsuccessful in finding evidence of them

We are learning logs and expos in calc (everyone's favorite topic) and I got stuck on two problems. First one is y = x^-x^2 and we have to find y'. On this one I can't figure out how to start it. I know we are suppose to show our work and then get help here, but I just can't figure out...

If I get a question that gives me a function defined in variables and then certain F(X) and F'(X) with numbers that equal the slopes, and I need to find the derivative of the first function do I just substitute in. For example: Find the value of F'(8) when f(x)/f(x)-g(x) while...

hmm my fundamentals are screwed up, I forgot what happens here for the most part. with the fraction exponents and the radicals. Factor the (\frac{1}{2}x^\frac{-1}{2}) into the (2x+7) ?

Ahh yes...My fault doubled it twice.. thanks.

Find the derivative of f when : \sqrt{x}(2x-7) When put into product rule form (following (f '*g) + (f*g') ) (\frac{1}{2}x^\frac{-1}{2})\ast(2x+7) + \sqrt{x}(2) Just started today making sure I am on the right track.

Sup all, In a comp sci class right now and one of our assignments is make methods for the following formula's. We don't need to know what they are/mean, since we are just make variable scripts that aren't actually solving anything. But I didn't know what some of them were so I figure...

Hey guys, I was wondering if anyone could tell me some books that just have problems in them for algebra and algebra two principals. Basically say a book that just has 1000 problems with the solutions with brief explanations for each type. So 1000 would be divided into exponent, radical...

nevermind got them done thanks to cookiemaster!

Both of the identities are equal to zero and I just am trying to simplify it down in terms of sin cos or tan.
