Chris 7 years ago بد و دیوانه قسمت ۴ دوبله فارسیWebWe also know that the half-life of 14C is 5730 y, and so once λt is known, we can use the equation λ = 0.693 t1 / 2 to find λ and then find t as requested. Here, we postulate that the decrease in 14C is solely due to nuclear decay. Solution Solving the equation N = N0e − λt for N / N0 gives N N0 = e − λt. 31.38 Thus, 0.92 = e − λt. 31.39 dd poličkaWebThe time required for half of the original population of radioactive atoms to decay is called the half-life.
