[Solved] To determine the half life of a radioactive element, a student plots a graph of \\ln \\mid \\frac{dN(t)}{dt} \\mid versus t. Here \\frac{dN(t)}{dt} is the rate of radioactive decay at time t If the number of radioactive nuclei of this element decreases by a factor of p after 4.16 years, the value of p is - When liquid medicine of density $$\rho$$ is to be put in - JEE (Advanced) 2010 Paper-2
