【题目】A radioactive substance decays so that the rate of decrease of mass at any time t isproportional to the mass m(t)present at that time.If the initial mass present is mo. set up and solve the appropriate differential equationand hence obtain a formula for m(t). ...
题目A radioactive substance decays in such a way that the amount of mass remaining after t\ days is given by the function m(t)=13e^(-0.015t) where m(t) is measured in kilograms. Find the mass at time t=0. 相关知识点:

Radioactive Decay: In nuclear chemistry, radioactive decay refers to a process where an unstable nucleus loses energy via radiation. Common types of this involve the emission of particles; this includes alpha decay, beta decay, and gamma decay. Answer a...
To solve the problem, we need to determine the half-life of a radioactive sample given that its activity drops to one-third of its initial value in 80 minutes. We can use the relationship between activity, time, and half-life in radioactive decay. 1. Understand the Relationship: The ac...
