Gce Model Questions Vol1 2021 Physics Question 28
Practice objective / multiple choice question 28 from the 2021 Gce Model Questions Vol1 Physics examination.
A radioactive isotope X decays to Y with half‑life \(t_{1/2,X}=30\ \text{min}\). The daughter Y itself decays to a stable nuclide Z with half‑life \(t_{1/2,Y}=10\ \text{min}\). Initially there are \(2.0\times10^{6}\) atoms of X and no atoms of Y. (a) At what time after the start is the activity of Y maximal? (b) What is that maximum activity (in decays per second)?
