Which side is the max entropy? P4(s) + 6H2(g) -> 4PH3(g) (delta H = +37 kJ)

Hello, Here is a piecewise function that I came over, and it does not seem to have a definite answer, and so I beg of your recondite knowledge to guide me on this one:f(x) = ax^2 + bx + c if -oo < x < 0 d if x = 0 [(x^2)(sin(1/x))]-2 if 0 < x < oo Find all...

Thank you, Mathman, for answering my question. I have done what you suggested by combining the equations of the two circles to find the intersection coordinates at Q. C1: (x-2)^2 + y^2 = 4 C2: x^2 + y^2 = r^2 It comes out to x = (r^2)/4 With this I can isolate r or x...either way, I now...

Hello, I came across this question and am wondering if anyone could help me on this...I don't even know where to start... (see attached image)Any help would be greatly appreciated! :biggrin:

The pan-flute seems to be made out of bamboo... I believe another member of the forum suggested celery. I guess I could try celery sticks made into a pan-flute. I'll post up any more difficulties over the weekend. P.S. Thanks for the advice!

The problem though, is that I don't even know how to make anything that can generate sounds with a fixed musical key, yet alone G major, which is rather high or a little low (in comparison to middle C). I have thought of making a recorder out of cookie dough, but then I would have trouble...

Lately there's this project assigned which requires me to apparatus/instrument which can play twinkle twinkle little star. It has to be completely edible. Here's a more comprehensive criteria: 1) at the presentation, teams may bring a tuning device to tune their instrument. However...

The 1.4 kg object below is at rest, suspended in deep space, far from any planet or other body. If the forces shown below are exerted simultaneously on the object, what will be the velocity of the object after 3.5 s? http://www.geocities.com/monsieurgoontaz/images/image1.jpg Split into x...

Each number in the bracket of three numbers is just representing a different dimension. E.g. (l, w, h)

A mass is supported by a spring so that it rests 0.5 m above a table top. The mass is pulled down 0.4 m and released at time t=0. This creates a periodic up-and-down motion, called simple harmonic motion. It takes 1.2 s for the mass to return to the low position each time. Could someone...
