its Q2B. no she did it correct - The graph shows background radiation plus radioactive sample radiation. So she got 37 by subtracting 15 from the initial value (52)

Sorry, not tryna diss or spread hate, but in in Q2C you went wrong. As the 37 counts/min in already without background raddiation
its Q2B. no she did it correct - The graph shows background radiation plus radioactive sample radiation. So she got 37 by subtracting 15 from the initial value (52)
nah she did it right, better recheck urself mate
@@tokyo7671 but i dont understand why they have to add back the background radiation after they got 18.5....
that’s because the graphs shows the reading WITH the background radiation (18.5)
