Radioactive disintergation always follow I order kinetics and is independent of all external factors and is represented by the relation N = N_(0) e^(-lambda t) where lambda is decay constant and N atoms are left at time t . The radioactive nature of element is expressed in terms of average life numerically equal to decay constant (1//lambda) however all the radioactive do not lose their radioactive nature in thier average life. The radioactive emission involves alpha, beta particles as well as gamma- rays.The penertrating power order is alpha lt beta lt gamma . The emissions can perntrate even thick steel walls but are however unable to penttrate Pb blocks. The S unit fo rate of decay is dps . The number of beta- particles emitted during the change, ._(a)^(c)X rarr ._(d)^(b) Y is:

Which of the following statements with regard to the heterodox sect between sixth and fourth century BC are correct? 1. The Jain ideas were already being circulated in the seventh century BC by Parshva. 2.

Buddha held that nuns could attain spiritual liberation just like a monk and granted them an equal status in the mendicant order. Select the correct answer using the code given below.

The following graph shows how t_(1//2) (half-life) of a reactant R changes with the initial reactant concentration a_(0) . The order of reaction will be
