A particle 'A' disintegrates into other 'B' and then 'B' into 'C'. Find the graph suitable for number of atoms of B vs. time.

A sample of a radioactive nucleus A disintegrates to another radioactive nucleus B, which in turn disintegrates to some other stable nucleus C. Plot of a graph showing the variation of number of atoms of nucleus B vesus time is : (Assume that at t = 0, there are no B atoms in the sample)

Two Radioactive substances X and Y emit a and B particles respectively. Their disintegration constants are in the ratio 2 : 3. To have equal rate of disintegration of getting emission of a and particles, the ratio of number of atoms of X to that of Y at any time instant is

There are two radio nuceli A and B. A is an alpha emitter and B a beta emitter. Their disintegration constant are in the ratio of 1:2 What should be the ratio of number of atoms of A and B at any time t so that probabilities of getting alpha and beta particles are same at that instant?

Replace A,B,C by suitable numberals:

A radioactive element A on disintegration gives two elements B and C. If B is helium and C is the element of atomic number 90 and atomic mass 234, the element A is:

s-t graph of two particles A and B are shown in fig. Find the ratio of velocity of A to velocity of B.

The rate of disintegration of a radioactive substance is …………………………… to the number of atoms present at that time .
