Homework Statement Just sketch the solid-liquid phase diagram from the data. the following data was collected from a cooling curve of the mixed metal oxide system XO-ZO, where X and Z are metals.Homework Equationshttp://img504.imageshack.us/img504/6415/chemdataur9.jpg The Attempt at a Solution...

Homework Statement This isI n't formatted properly because I don't have much time. The wave function is f(x) = e^-|2x| I need to normalize this functionHomework Equations The normalization condition is S f^2dx=1 (that S is an "integral" sign and the limits are from - infinity to +...

So the "intermediate object" is the image due to the first lens and it is located -15 cm (from 5cm - 20cm) on the incident-light side of the second lens. the focal length of the second lens is 10cm and s = -15cm so s' is 1/s' = 1/f - 1/s = 1/10cm - (1/-15cm) = 0.167 cm s' = 6 cm to the...

Homework Statement Two "waves", characterized by cosx and cos^2(x/2) interfere. Using phasors or complex numbers or trigonometry as necessary, aggregate "cosx + 2cos^2(x/2)" - i.e. rewrite as a single cosine. Homework Equations I was told that there is an error in the way this questions...

I just found this in the book: as s --> infinity s' --> 0.5r = f so I can just neglect s then and s' becomes 1/s + 1/s' = 1/f 0 + 1/s' = 1/f s' = f = 20 cm

Homework Statement There are 2 lenses separated by 5 cm. Very far to the left of the first lens is an object (the distance of the object from lens one is NOT given). The focal length of lens 1 is 20 cm and the focal length of lens 2 is 10 cm. Where is the image due to the first lens? State the...
