If is given that radium decomposes at a rate proportional to the amount present.If po of th original amount of radium disappears in l years,what percentageof it will remain after 2l years?

If is given that radium decomposes at a rate proportional to the amount present. If p % of th original amount of radium disappears in l years, what percentageof it will remain after 2l years?

Radium decomposes at the rate proportional to the amount present at any time. If p percent of amount disappears in one year, what percent of amount of radium will be left after 2 years?

Radium decomposes at a rate proportional to the quantity of radium present. It is found that in 25 years, approximately 1*1 precent of a certain quantity of radium has decomposed. Determine approximately how long it will take for one-half of the original amount of radium to decompose ? (log_(e)0.989=-0*01106, log_(e)2=0*6931)
