In the nuclear industry, workers use a rule of thumb that the radioactivity from any sample will be relatively harmless after 10 half-lives. Calculate the fraction of radioactive sample that remains after this time period. What does this mean for the Rocky Flats cleanup operation, which occurred at the former Rocky Flats Plant just outside of Boulder that generated plutonium triggers for nuclear weapons ( 239 Pu decay rate

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
