"positron" for another lepton?

is image intensifiers accepted instead of contrast material ( i dont take bio so wasn't sure if it goes in blood :|)

For strong nuclear force it said it "travels much closer to b(iii)" and ans is 4...*10^-15 and in wikipedia range is 1-3*10^15 so shouldn't it be repulsive then cause distance is 'much' smaller?

I put a positron as well but im not sure. I marked myself down just in case it isn't but I cant see why it ia not a lepton

Thats exactly what I thought. Its what the question implies. I cant see why its attractive.

It will be repulsive if you get close enough ie less than 1 fm . I'm sure both answers are acceptable if explained clearly.

Do you think this is enough for an a*? 60/60 on corsework, 50/60 on G484 and 75/100 on G485

How the hell do people get full marks in the coursework? I got A in all exams, and I'm struggling to get a B in the coursework, got low C and high C.

Yeah same literally put so much effort into coursework and dont see how people manage to get full marks? Too much help from teachers maybe? Or not enough help from our teachers? ahaha

What do you need to get an A*? Like I know for maths it's an average of 90% over C3 and C4. Just wondering what it is for physics. My teacher told me you just have to get over 90% on just one of the written papers but that seems a bit odd. Any help?

Lol probably, my cousin in another school said that the teacher literally tell them what to write and they all get full marks, while I was studying for hours learning all the crap and got a C because of boundaries lol, my life would be so much easier if I had gotten A's in coursework, I'm now sitting on the edge of my seat hoping my A's are high enough to give me an A overall so I can get to Uni, and physics isn't my strongest subject so it's not helping either lol.

The chemistry teachers in my school literally tell their students the answers and they all get full marks but in physics we get so little help! and im working my arse off just to pull up the B in coursework by getting high A*'s

Thank you so much! I think I get 84/100 in this paper! For g484 I think I get 45/60. For the practical I think I get 37/40 Do u think I will get an A or even an A*?? Many thanks!
