    Has anyone every gotten a 100% in chemistry or physics trial (just curious)!!

    bruh - technically OH should be right if the bond was to the oxygen. Unless ofc they asked for an expanded formula. Ig faculties never want students to get a perfect mark in their tests!!! But damn thats a legendary score

    Ampere definition limitations

    oh sos - I remember answering that the old definition was based on the accuracy of the length of a metre and that the new one is based on the accuracy on the measurement of time - both of which is not absolute as we now know due to special relativity. Not sure if this is right, but this is what...

    What is the most feasible way to explain the speed of light as the speed limit?

    ye got that - in essence, as the velocity approaches the speed of light, the relativistic momentum approaches infinity, and the mass begins to dilate as a result (since mass is a measure of energy as per the energy-mass equivalence proposed by Einstein), since mass is a measure of inertia, and...

    ye fair thats what I would have written lol

    What is the most feasible way to explain the speed of light as the speed limit?

    ^^^^ Any insight would be appreciated!!! I have seen responses from the stance of discussing impulse as opposed mass dilation....

    Doppler vs pressure broadening?

    fair enof that makes sense - suppose we were asked to explain a broadened line spectra, is it still viable if we list both of these as reasons?

    Doppler vs pressure broadening?

    fair - how can we differentiate these two when given a spectra, since both of these result in the thickness of the line spectra increasing? Thanks!

    Doppler vs pressure broadening?

    ^^^^ wut the difference between these two when it comes to spectra? Thanks!!!
