Did you find it as tricky as I did?

I don't understand why D is correct - "charge separation is the process of an electron in an atom or molecule, being excited to a higher energy level by the absorption of a photon and then leaving the atom or molecule to a nearby electron acceptor." how is this happening in the tube?

Obviously the red eddy current can't flow due to the slit - but what stops the smaller blue currents from flowing? I understand that they would have a very small effect because of their size but they would still be there?

I said C for the copper cylinder one - there will still be small eddy currents generated in the cylinder, just not big ones going all the way around

How do you split it into that when the numerator is only x?

I can only save it as a zip file sorry! thanks for the help xx

It is so worth it - if you enjoy maths it is an awesome course. It does require alot of practise but if you are only going to have 11 units with it you will have time. And the scaling will help you get a good atar, especially if your english marks aren't too flash :)

12 Monkeys: the first season has just come out on DVD - its so thrilling and dramatic Also ily the Walking Dead And I've started watching Wayward Pines with my bf - it's really interesting

NOOOO not at all, to quote my beloved maths teacher, at the end of year 11 your results are "thrown out the window". If you ask me it's actually quite a good and healthy option to take year 11 nice and easy, because then you will be ready to absolutely smash year 12. Too many people in my year...

Prac exams generally focus on how you record the data and manipulate and analyse it. When drawing a table use a ruler and make sure you enclose the box fully. Allow room to record repeated trials. Use a pencil when you are writing down your results, then go over it in pen later. Don't forget to...

Thank you so much! I really appreciate it xoxo

I'm not sure how to approach this question - I tried using F=qvBSin(theta) but I can't work out what the magnetic field strength is? does anyone know how to do it? An electron moving at 4.0x103 m/s enters the electric field between two metal plates separated by 10cm with a potential...
