It's been a year since I was issued my driving licence. I have never driven automatic transmission cars, so my idea about them is very faint. I know that there is no clutch pedal, and one doesn't have to shift gears while driving forward - that's it. Last day, I was watching a TV show where...

Hello, I have answered the question below but would like some advice on whether I can improve my answer or if anyone is able to check whether I have made any mistakes ? i. 1 V = 1eV in a 1:1 relationship, therefore; 6.5 TeV = 6.5 TV = 6.5 *10^12V ii. E=W W=V * Q Q=number of particles * charge...

I honestly just have no idea where to start on parts c and b. I tried 1.1*10^-12 N x 3218 m for part a, which was right. But I'm lost on b and c. I'm also wondering if we have to include a gamma factor in any of this, but I'm unsure how or where. Any help would be amazing.

In accelerator physics, mapping matrix is often used to describe particle's motion.For a given one turn mapping matrix,namely M(s+L|s) ,and initial (x,x').After matrix multiplication, I find the value of (x,x') changes which means particle's position and angle changes at the same s after one...
