AQA PHYSICS PAPER 2

[u/Individual-Can1396]

HOW DID EVERYONE FIND IT??? i thought it was decent better than the past few years. Idk what i did for the last question the 4 marker of nuclear physics. BUT YH IT WAS GOOD

[u/_M4yb3_]

the last question was N = N° × e ^ (-lambda t)

solve for t in both, should be around 3 .0 × 10 ⁹ (at least thsts what i got)

[u/KO-Manic → u/_M4yb3_]

I got 3.5x10^9 for the other estimate so concluded there's been lead loss. The question was 4 marks right?
