Consider two nuclei of the same radioactive nuclide. One of the nuclei was created in a supernova explosion 5 billion years ago. The other was created in a nuclear reactor 5 minutes ago. The probability of decay during the next time is

Consider a radioactive material of half-life 1.0 minute. If one of the nuclei decays now, the next one will decay

Consider a radioactive material of half-life 1.0 minute. If one of the nuclei decays now, the next one will decay

A radioactive nulei has half-life of 1.0 minute. If one of the nuclie decay now, the next nuclei will decay after:

A sample of a radioactive isotope contains N nuclei at time t.At time (t+triangle t) ,it contains (N-triangleN) nuclei of the isotope. For the period trianglet ,state in terms of N,triangle N and trianglet , the probability of decay of a nucleus.

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?

A particular nucleus in a large population of identical radioactive nuclei did survive 5 halt lives of that isotope. Then the probability that this surviving nucleus will service the next half life is
