Question # 1

Wh Geiger counter is not suitable for fast counting?

Ans 1: Geiger counter is not suitable for fast counting because of its longer dead time.The positive ions take several time as long to reach the outer cathode,because positive ions are very massive than the electrons.During this time further incoming particle can not be counted,This time is called as the dead time of counter which delays fast counting system.

Question # 1

If nucleus has a life of one year,does this mean that it will be completely decayed after two years?

Ans 1: No it will not decay completely after two years.
Numbers of atom at initial stage =N_o
number of atoms decayed after first year =1/2N_o

Question # 1

What are isotopes?What do they have common and what are their difference.

Ans 1: Isotopes are such nuclei of an element that have the same charge number Z but have different mass number A.It means,in the nucleus the number of protons is the same but the number of neutrons is different.

Question # 1

Define Hadrons and Leptons.

Ans 1: Hadrons: These are not elementary particle,They are composed of other elementary particle called quarks.The example of hadrons are protons,neutrons,mesons etc,They experience strong nuclear force.
Laptons: The are elementary particles.They do not experience strong nuclear force,The example of laptons are electrons .muons and neutrinos etc.
