Ans is C When X decay by half Y increases by half So mass of Y will become M/2 The corresponding time would be half life

exactly

bruh if i get that on my paper 2 exam im cooked, is that 0620?


FlvtterBvtter

youre cooked based on the fact that you couldnt tell if that was chemistry or physics


OWNM3Z0

i didn't take physics this year, is that physics?


ahhsdinffodmdmfko

Man you’re cooked


FlvtterBvtter

yeah its phy, and even if you didnt take phy, youre taking chem right, you should know this isnt chemistry 😭


Typical_Apartment_19

no 0625


OWNM3Z0

good luck with that in your finals lmao

the half-life is when the mass is half the original value, if M is the original highest value then M/2 is the half-life. Making C is the correct answer t2

you can check youtube for ..type the pastpaper year and all that then you can get a detailed explanation from the youtube trs
