    What are some experimental errors associated with spectrophotommetry?

    This isn't an actual calculation homework problem I'm having but rather a lab discussion. I'm trying to find experimental errors of the experiment where you determine an equilibrium constant using spectrophotometry. The reaction is: Fe 3+ + SCN - = FeSCN 2+ we used Fe(NO3)3 - iron (3)...

    Spectrophotometry question - anyone experienced with it?

    Hey guys, I'm doing an experiment trying to find the equilibrium concentration for the reaction: Fe 3+ + SCN- = FeSC 2+ So now, I have already graph the calibration curve and found the constant for absorption and concentration. This next part of the experiment we use a constant volume...

    High School Snell's Law and the particle model for light

    So I did a "waves in two depth medium refraction" lab and I measured the angle of incidence and the angle of refraction. So doing the sin i/ sin R, I get the value of 1.22 for all the sets of data. A question asks, do the values (1.22) serve as evidence for or against a particle model...

    High School Any ideas of how gyroscopes are applied in environment?

    I am writing an STSE and of course the last section is the environment section. I suck at this part because sometimes it's hard for me to connect to all categories. So how does a gyroscope relate with the environment? If you know of a small topic on this, please let me know and I can just go...

    Undergrad How exactly does a gyroscope relate to angular momentum?

    Wikipedia says that a gyroscope is based on the conservation of angular momentum. This whole day I'v been doing my report on gyroscopes and explaining their precession. But how do I connect the conservation of angular momentum to this? I don't know where to start. I have seen videos...

    High School Where do I find information about gyroscopes?

    I'm doing a physics fair on gyroscopes but I absolutely can not find good organized information. I looked up almost every link from a google search but most sites are crappy. I even looked in 2 libraries but no books are found. How can this be? I thought gyroscopes have been out for a long...

    Is there a limit to how many derivative rules you can do within another rule?

    Like for this question. y = sqrt ( 5x - sqrt ( x^2 + 3 ) ) - this question is a square root within another square root. So I rearranged it like this: y = ( 5x - ( x^2 + 3 )^1/2 ) ^1/2 dy/dx = 1/2 ( 5x - ( x^2 + 3 )^1/2 ) ^ -1/2 x ( 5x - 1/2 ( x^2 + 3 )^ -1/2 ) I got up to there, but...

    High School Any ideas for grade 12 Physics project?

    I have this so called in class physics fair and its pretty much a project. But I'm having trouble thinking of a topic that is not of the common ones other people have done. Of course it has to be related to the grade 12 physics course and be within a small range budget? The grade 12 course...
