Homework Statement Initially, a particular sample has a total mass of 200 grams and contains 256 x 1010 radioactive nuclei. These radioactive nuclei have a half life of 1 hour. (a) After 3 hours, how many of these radioactive nuclei remain in the sample (that is, how many have not yet...

[b]1. Astatine-210 decays through a beta-plus decay process. Use the table in section 29-8 (see the link above) to find the relevant masses for this decay, and calculate the energy (in MeV) released by the decay of one such atom. You can neglect the mass of the neutrino that is one of the decay...

you need to include the minus sign!

you put down 0.5m^2 for the area when it should be 5m^2 since you are converting from cm to m

is the velocity of particle 1 still the same in field B (needed to find the value of the magnetic field in B)?

thanks!

How did you find the radius for part D?
