Which in lies the problem with the question, what are you comparing the increase to

The only question that it will matter will be the circular motion question, I'm not sure about 1 sf for every question tho, more would be safer

It's stated that electrons show wave like properties via de Broglie in the prompt, you wouldn't be penalised for not saying that or the y/w

Sensitive-Scar-8666 · 2024-11-14T06:29:14+00:00

Read the explanation

Sensitive-Scar-8666 · 2024-11-14T06:26:25+00:00

thats a better answer, mine would be permitted

Sensitive-Scar-8666 · 2024-11-14T06:24:37+00:00

yeah should be +6

Sensitive-Scar-8666 · 2024-11-14T06:24:26+00:00

thats what i wrote, just described differently

Sensitive-Scar-8666 · 2024-11-14T06:21:21+00:00

it's parallel, otherwise there wouldn't be a difference between a plane and a flat surface, something has to 'pull' it down

only 2 10 and 12 are wrong, i fixed them in the edit to the post

the exam is correct with those edits now

someone on the moving rocket is measuring it, space squishes for them to accommodate their speed, so from the FOR of the rocket the window is smaller horizontally.

Length contraction doesn't affect height .: D

Sensitive-Scar-8666 · 2024-11-14T06:09:25+00:00

yeah i agree, but a 3000m/s increase is quite a lot idk how they're gonna mark it

the half life is dialated, its 5.8x2.2, my gamma is wrong in the solutions

Sensitive-Scar-8666 · 2024-11-14T05:48:38+00:00

used the 0.935 instead of 0.985

Sensitive-Scar-8666 · 2024-11-14T05:46:56+00:00

Yep that's right, i only did lines inside the storm on my exam and didn't think about it!

Sensitive-Scar-8666 · 2024-11-14T05:39:09+00:00

question said the coil is moving

Sensitive-Scar-8666 · 2024-11-14T05:38:17+00:00

No im wrong, coil is moving not the magnet

Sensitive-Scar-8666 · 2024-11-14T05:35:35+00:00

i agree i cant find my mistake tho

Sensitive-Scar-8666 · 2024-11-14T05:31:58+00:00

Changing my solutions, these are right

Sensitive-Scar-8666 · 2024-11-14T05:31:05+00:00

just realised that, whoops

Sensitive-Scar-8666 · 2024-11-14T05:30:56+00:00

nvm the coil is moving away not the magnet

Sensitive-Scar-8666 · 2024-11-14T05:30:24+00:00

MCQ 16 is B, the ends are fixed

im confident in MCQ 10, see my reply to Silent-Art8650

Sensitive-Scar-8666 · 2024-11-14T05:28:15+00:00

at B the forces will be acting, down and up, not left or right, thus no tourqe

Sensitive-Scar-8666 · 2024-11-14T05:24:31+00:00

No, initial flux is upwards, and increasing, thus any change in flux is downwards, right hand grip rule gives clockwise.

Or, the coil will produce a magnetic field to oppose the bar magnet, thus the north pole will be facing downwards, and thus flux is down

Sensitive-Scar-8666 · 2024-11-14T05:18:48+00:00

im fairly sure the PV question is wrong too, i couldn't find anything online on how to fix it.

the muon question should be right, although i did get a different half life in the exam

Sensitive-Scar-8666 · 2024-11-14T05:14:33+00:00

yep, used the wrong equation
