    Pyrex glass rod is immersed into wesson oil

    No, but I've googled it and found out the relation that: refraction1 * angle1 = refraction2 * angle2 refraction1 / refraction2 = wave velo.2 / wave velo.1 thus if the refraction of two things are equal where refractoin1 = refraction2 thus it having both equal each other the...

    Pyrex glass rod is immersed into wesson oil

    http://littleshop.physics.colostate.edu/onlineexperiments/Pyrex%20and%20Oil.html I want to show the math of what happens when the pyrex glass rod is immersed into wesson oil making the bend in light identical, but I don't know where to start? Suggestions? Or equations you believe I should...

    Is there any online sites that simulates circuits

    I'm looking for programs or a site that simulates what happens in my lab on connecting circuits because I try doing the labs but I am usually behind... I don't get a chance to practice a lot and it's a one shot deal thing... Any suggestions would be nice.

    Decompilers that converts a program back to it's original source?

    Earlier this week I had a talk with someone who told me that they've seen a decompiler which is able to convert a program back to it's original source in a language such as C++. From my knowledge I believe this is impossible, but I was wondering if anyone else knows anything about this?

    Why Is 0 dB Considered the Maximum Recording Level in Digital Audio?

    The program shows the dB level going from negative infinite to 0. None of the responses above really tells me much. Can someone please make it clearer.

    Why Is 0 dB Considered the Maximum Recording Level in Digital Audio?

    Recording on the computer physics question? The meters show signal levels in dBFS (decibels below full scale), where a level of 0 dB is the maximum amplitude possible before clipping occurs in a program such ad Adobe Audition. However my question is why 0 db? When 140 db is the painful...

    How Does Friction Affect the Velocity of a Mass on a Spring?

    New attempt: Us = W = U = (1/2)k x^2 (1/2)(10 N/m) (1m)^2 = 5 N*m Ug = (0.1 kg)(1m)(-9.8 m/s^2) = -.98 J Uf = 5J W= Us - Ug + (5J) 5J -.98 J + 5J = 9.8 J So far, is this correct?

    How Do You Calculate the Center of Mass for Multiple Objects?

    the sum of the center mass equation... and you got to break it down into y and x... there is an similar example online, i'll look it up for you

    How Does Friction Affect the Velocity of a Mass on a Spring?

    New attempt: Us = W = U = (1/2)k x^2 (1/2)(10 N/m) (1m)^2 = 5 N*m Ug = (0.1 kg)(1m)(-9.8 m/s^2) = -.98 J W= Us + Ug+ (-5J) 5J + (-98 J) + (-5J) = -.98 J b) W = E - Wnc (Work energy Theorem for Systems) W = 0 Because there is no internal nonconservative forces.. I still haven't...

    How Does Friction Affect the Velocity of a Mass on a Spring?

    So I am assuming that its: W = Us + Ug + 5Nm However how would I find Ug without knowing it's height?

    How Does Friction Affect the Velocity of a Mass on a Spring?

    Question: A 0.2 kg mass is attached to a spring k = 10 N/m) and hangs vertically near the Earth's surface (g = 9.81 m/s2 ). The mass makes contact with a wall as it moves vertically and a constant frictional force of magnitude 5N acts on the mass as it moves. a) Calculate the amount of work...
