Half-life is the period of time it takes for a substance undergoing decay to decrease by half. [ Half-lives are very often used to describe quantities undergoing exponential decay—for example radioactive decay—where the half-life is constant over the whole life of the decay. ]

Weegy: Hello may i help you with a Question? User: i did Weegy: how can I help you? User: describe einsteins famous equation e=mc2 using two well known conservation laws? Weegy: E=mc2 is a version of Einstein's famous Relativity equation. Specifically, it means that Energy is equal to Mass times the speed of light squared. In essence, it states that there is an equivalence between mass and energy. [ [ This simple statement has many ... (More)

Weegy: Hello may i help you with a Question? User: what are two well known conservation laws that can describe einsteins famous equation e=mc2
Weegy: Laws of Thermodynamics
The Laws of Thermodynamics are considered part of the bedrock of physics (and among physicists, about as immobile as bedrock). But there are two problems.
The first is essentially a clarification. [ The Laws of Physics (including specifically the Laws of ... (More)
