Greetings all/any: Homework Statement Take the Laplace transform of the following initial value problem and solve for Y(s) = L{y(t)} y'' - 3y' -28y = 1 if 0<t<1 0 if 1<t initial conditions: y'(0) = y(0) = 0 a. Y(s) = ? b. now find the inverse transform to...

Yeah, .076 multiplied by the actual result (ratio, volume) was right. Thanks again!

No, I have no idea what he expects. Of the entire problem set for the section, this is the only problem with uncertainties. This is the first homework set though, but/and it's 'physics for engineering majors'. We haven't covered before, so maybe you're right and he's looking for a simpler...

Aagh - I'm so sorry, I copied the original problem wrong, it's not .002, but .02cm (and still .005cm for the other). Sorry for the confusion. :/

Alright. I don't think I see what you're saying, to me it looks like you're just repeating to do what I've already done, which is: . Are we speaking past each other? because as I said, the .07...number I keep coming up with is incorrect. MasteringPhysics automatically checks answers, it's...

Thank you! I just realized that to find the volume of the cylinder, I used the radius (1/2 diamter > 8.5*.5 = 4.25), not the diameter. So sqrt[(.02/4.25)^2 + (.005/.07)^2] = .0715834209 - which would not make a difference in the final result since we need to round to one sig. figure, and it...

[SOLVED]Calculating Uncertainty in multiplication/division (Volume&Ration) Hello all. Homework Statement As you eat your way through a bag of chocolate chip cookies, you observe that each cookie is a circular disk with a diameter of 8.50 +/- .002cm and a thickness of (7.0×10^−2)...
