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

For a radioactive material, half-life is 10 minutes. If initially there are 600 number of nuclei, the time taken (in minutes) for the disintegration of 450 nuclei is.

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?

Four thousand active nuclei of a radioactive material are present at t= 0. After 60 minutes 500 active nuclei are left in the sample. The decay constant of the sample is

In a sample of radioactive material, what percentage of the initial number of active nuclei will decay during one mean life ?

A radioactive material is made at the constant rate of 10^(4) nuclei per second and the material is getting decayed with decay constant 0.0123 month ^(-1) Activity of material after a very long time (if initially there was no radioactive material) is:

The graph shows the log of activity ( log R ) of a radioactive material as a function of time t in minutes The half -life (in minutes) for the decay is closest to
