WebFeb 20, 2024 · Therefore, the equation N = N 0 e − λ t can be used to find λ t. We also know that the half-life of 14 C is 5730 y, and so once λ t is known, we can use the equation λ = 0.693 t 1 / 2 to find λ and then find t as requested. Here, we postulate that the decrease in 14 C is solely due to nuclear decay. Solution WebA function that models exponential growth doubles in size after a characteristic time, , called the doubling time. The exponential growth function can be written in the form. where. is the initial or starting value of the function. is the time that has passed since the growth began.
