Yeah, later they ask some stuff about "do these two times completely agree?" How convenient. Then they ask how I could use them to approximate the half-life. :confused: Maybe the average or something.
Okay, I've got this problem in my Chemistry class. It's about half-lifes and all that. If this is the wrong place to post this, then somebody can move it I guess.
I've got a 10.0 g sample of an unknown. They give me the following info, wanting me to plot it on a graph. That's the easy...
A magnet is directly between a Geiger counter and a radioactive material. If no radioactivity is registered, what kind of particles are being emitted by the radioactive substance?
