Damn hopefully clutch a band 5 with the last few mc guessesprobs a high band 4

For 10 its D because the force on XY is the same all the way round because its a 2D side always perpendicular to the field. Q16 I guessed D and got it rightcan some explain 16, and isn't 10 B because field is parallel
i was banking on them not asking a trick question so i didnt put zero but flux is independent of current anyways so there would be an emf inducedBut for ii , it asked for the max emf in the ring with the incomplete flux linkage , so wouldn’t it just be 0???
it will be similar to last yearsWhat would a 70 raw be?
doubt it, definetily harder that last year, so scaling will be decentit will be similar to last years
i won’t lie i’m not 100% sure but ig we will find out , i thought it was just a trick question ngli was banking on them not asking a trick question so i didnt put zero but flux is independent of current anyways so there would be an emf induced

I just put in whatever the lower of the two given wavelengths was, I dont remember the question so I may have done it wrong but thats what I remember doingWhat was 23 b, did you just do E=hc/lambda and minus the wavelengths on the denominator?
yh I didn’t like that qI just put in whatever the lower of the two given wavelengths was, I dont remember the question so I may have done it wrong but thats what I remember doing
don't you just convert max wavelength to frequency and then convert to energyI just put in whatever the lower of the two given wavelengths was, I dont remember the question so I may have done it wrong but thats what I remember doing
Yes but I did E = hc/lambda instead of converting to freqdon't you just convert max wavelength to frequency and then convert to energy
are both correct?Yes but I did E = hc/lambda instead of converting to freq
The question wasn’t asking that thoughBruh is our universe constantly expanding rn? For q20 because I picked A because hubbles law
Yeah because its the same thing just two different waysare both correct?
pretty decent, hopefully got 20/20 m/c and then other than that I’m happy with most answers other than the projectile motion one where I forgot the horizontal motionHow did everyone go?
Thought q20 is A cos the universe expansion was accelerating because as the distance increases the velocity increases proportional, so it’s accelerating.The question wasn’t asking that though
apparantly the rate of expansion is accelerating. literally third derivative type of thingThought q20 is A cos the universe expansion was accelerating because as the distance increases the velocity increases proportional, so it’s accelerating.
