This came in a test I did recently - i think...

Wut would you guys get for the above - just wanna confirm my ans. Thanks! Also does anyone have the answers to the Penrith 2021 chemistry trial?

is it D?

^^^^ Thanks!

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

ok cool - solid strat

^^^^^ Thanks :)

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...

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

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

seems like a q I have seen before - so I can help you with that

What trial paper did you get that q from if you do not mind?

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?

^^^^^

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!

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

sure if you want to lol

Yea thas right - act its both (edit)

can you show me how he used the term velocity pls - I know he equated the weight and electric field force together to get (mg = qE --> Q = mg/(v/d)), but how did he use the diameter and term velocity of the oil drops to get the mass of the oil drops themselves? Thanks!
