Extracted text: PROBLEM 24 - 0580: spontaneously disintegrates at a rate Radioactive material that depends on the amount of material that remains. That is, a given fraction of . the remaining material disintegrates each day. Write a FORTRAN program to simulate this system, using the modified Euler's method, from time t = 0 to time t = t; if the amount of material remaining at time t is N(t); N(0) = N'o; and P is the percentage %3D (per unit of time) of the remaining material that decays. Compare the modified Euler approximations with the exact values.
