1.	The half life of a radio active substance is 13 years then the decay constant us
Answer» n :Given :-The half LIFE of a radio active substance is 13 years.To Find :-Decay constant of radio active substance.Formula :-▪ Half life of a radioactive substance is given byCalculation :-Additional information :-The radioactive radiations are of three types, α-rays, β-rays and r-rays. An α-particle CARRIES two units of positive charge and four units of MASS.A β-particle carries unit NEGATIVE charge and has negligible mass.
