A radioactive nulei has half-life of 1.0 minute. If one of the nuclie decay now, the next nuclei will decay after:
Consider a radioactive material of half-life 1.0 minute. If one of the nuclei decays now, the next one will decay
At t=0 we begin to observe two identical radioactive nuclei with a half life of 5 min. At t=1 min one of the nuclei decays. Does that event increase or decrease the chance of the second nucleus decaying in the next 4 min. or is there no effect on the second nucleus?
Why do radioactive element decay?
A certain radioactive element has half-life of 4 days. The fraction of material that decays in 2 days is
A radioactive elements has a half life of 2500 yrs. In how many years will its mass decay by 90% of its initial mass?
A radioactive sample has half-life of 5 years. Probability of decay in 10 years will be.
A radioactive substance has a half life of 60 minutes. After 3 hours, the fraction of atom that have decayed would be.
