Depended on your method, the answer will be 127 or 128

WAS THIS AN OPTIONAL TOPIC??😥

Both methods will get the marks chill

No it won't. The whole point is that you don't know the mass of an electron. So you have to eliminate it. They've deducted marks in the past for that

who here did Turning Points?

In the astrophysics paper, the very last question was because of the Big Bang right?

is it just our class in the whole of the UK that does medical physics?

I put dark matter. I think the Big Bang caused the expansion but they don't know why it's accelerating hence dark matter?
that was amazing

6 marker was good. For graph straight line from m0 till speed is about 0.6c then curves upwards rapidly and is asymptotic with v=c (never touched)

Single handedly lowered the grade boundaries for that exam
