I know this feeling...

I need 113 for an A yet 53 for a B, insane on the marks difference.

I had a decent A last year but i dropped massively in Unit 4 with 70UMS, i re-sat last Thursday but i think it went just as bad... Unit 4 doesn't agree with me!

On the plus, i'll be over the moon with a B, it's what I need for University
aaah your fine then ! I need an A, or I'm not going university

Then teach me, because i hate relativity. Huygens and Newtons any day, it's hands down my fave thing in Unit 5.
I think this is a good video :

Goes through all assumptions too

Not good

Where have you applied? They do allow some people to slip up here and there, and 110 isn't unreachable especially not with Unit 5 boundaries

To be honest, i'm not 100% sure myself how bad is that.

The bloke that stays on Earth because 'moving clocks run slower' that's about all i could tell you. So someone please explain to me too, hehe

To keep it short... when you go really fast, time slows down. you have two identical twins... one goes on a spaceship going all fast... the other stays on earth. One of the twins (the one on earth) can potentially be many years, decades or even centuries older than the one who has been flying around lol

King's College London, they do let you slip up by a grade yes... but I've already slipped on chemistry hehe

If you arrange the Kinetic theory equation for the root mean squared speed,
One side is all divided by mass.
Nitrogen is bigger than Helium therefore a lower crms?

Hmm, as everything is relative, couldn't you say that from the spaceships reference frame everything else is moving quickly, and therefore the earthly twin will be going faster, and is therefore to be the younger twin?

If you'd have asked a few weeks ago I much preferred thermal, but now it's all about astrophysics

Help... forgotten how to get from
ev=1/2 mv^2

mv^2 / r = Bev

to

e/m = 2V / B^2 x r^2

:confused:


Thanks
