NESA wants to: Know your locationImagine NESA employees read this and next year advanced mechanics becomes euler langrange and hamiltonian mechanics
Do you have the answer to this? So I can check
This was meant to be in our trials. What is this hahahaha
701.9nmDo you have the answer to this? So I can check
how do you even do this. Are you supposed to use snells law or something whatt...

Its just extremely badly worded, I believe you get the correct answer if you just say the angle is 45 degrees and it occurs at the 5th order maximum, since that way the two maxima 5 away from the center subtend an angle of 90. The diagram honestly makes the question more difficult with the weird zig zags.how do you even do this. Are you supposed to use snells law or something whatt...
Thats what i did but i didnt get 701.9 nm, rather 707.1 i believeIts just extremely badly worded, I believe you get the correct answer if you just say the angle is 45 degrees and it occurs at the 5th order maximum, since that way the two maxima 5 away from the center subtend an angle of 90.

This question seems a bit difficult to answer, but I will give it my best shot (Im assuming Morgan-Keenan refers to stellar spectral classes divided by temperature?) I would assume that you say:Alright here’s the next question:
Explain the effectiveness of the Morgan-Keenan system in stellar classification. (4 marks)
Yeah theres also a typo in the marking guidelines (This is fron the TEC exam). Instead of saying d*sin45 they say d+sin45. Really badly designed question lol.Thats what i did but i didnt get 701.9 nm, rather 707.1 i believe
Lol we never learned this, sorry, I just assumed it was a name for the usual temperature classifications.Ah, but remember the MK system doesn’t just describe the usual OBAFGKM , it also has sub classes of luminosity (I-IV) (iirc) and temperature (0-9), e.g. the sun is a G2V star.
the atar notes topic test book covers it because there is a dot point exploring stellar classifications, but i dont think its super necessary, just an extra measureLol we never learned this, sorry, I just assumed it was a name for the usual temperature classifications.
Ok I will keep it in mind, I edited my original comment to include a bit on it, the answer feels super bad though.the atar notes topic test book covers it because there is a dot point exploring stellar classifications, but i dont think its super necessary, just an extra measure
I meant neutron star not supernova hahahha. I swear my number one dumb mistake is getting distracted and writing the wrong word down in physics.Also did you say the position helps predict the formation of a black hole or supernova? Because the black hole arises from the supernova if the mass of the star is between 8-50 solar masses, otherwise it becomes a neutron Star. Other stars die by pulsating their outer layers out to form a planetary nebula leaving behind a white dwarf
That was a stupidly worded q, i initially thought it was induction but its just RHRView attachment 27536
Could someone please explain the mechanics as to why this is A? I understand it has to do with Lenz's law but not sure how to approach it.
