Question: in a bicycle pump the preasure increases from [p1 = 10^5] to [p2 = 30^5]. If the process is adiabatic ant the air starts at [T1 = 293 K], find the maximum temperature of the air in the pump. (Assuming air can be treated as an ideal gas) Attempt: So using the 1st Law and given...

"Sketch the form of the Fourier transform" - is this right? Question ~ sketch the "form of the Fourier transform" for the function: f(k) = sin^2(ka/2) / (ka/2)^2So I'm thinking it will look like a cos [or sin] graph (shifted so that its 'above' *f(k)=0*) and that there will be some sort...

Ok, here goes: Homework Statement So I've come across this 2nd ODE which I am to "solve ... for a general solution": d^2y / dx^2 - dy/dx + y = cos(x) - sin(x) :-p and then evaluate the "particular solution" using the boundary conditions y=L...

Is it theoretically possible to find "g(x)" from this equation? So through my workings on this question I came up with this equation: (x^2)yz - (y^2)(x^2) - x + g(x) = g(y,z) * where g(x) is some function of x and g(y,z) is some function of y and z I'd like to derive g(x) from this...

That makes so much sense. Sometimes when tackling some of these questions I feel like a 3yr old playing with a bunch of shaped blocks trying to cram a stupid square one into that smug *** circular hole. Not my finest moment.

1. Homework Statement "A thin piece of metal foil of thickness 0.0700mm separates one end of two pieces of optically flat glass. The top sheet is 12.0cm long. Light of wavelength 529nm is normally incident on the glass. How many interference fringes are observed per cm in the reflected...
