10. Explain what each part represents in the following decay scheme: Po 138 210 4.502 Me...
Radioactive bismuth, Bi-210 (half-life of 5.0 days), decays to polonium, Po-210. Radioactive Po-210 (halflife of 138 days) decays to stable lead, Pb-206. a) Draw the decay scheme for Bi-210 to Po-210. b) Draw the decay scheme for Po-210 to Pb-206. c) If you start with 5.0 X 10-3 Ci of pure Bi-210, calculate the activity of Bi-210 and Po-210 after 30 days.
Complete the following decay processes by stating what the symbol X represents (X = a, B-, B+, or y). (a) 228 Τη – 224 Ra + X Ο Ο Ο Ο (b) 210 Pb - 210 Bi + X Ο Ο Ο Ο Ο 208 ΤΙ* - 208 ΤΙ + X 81 81 Ο Ο Ο Ο (α) 13N- 13C + X Ο Ο Ο Ο
the equation that represents this problem, explain what each part means and why you wrote it that way, and then solve for how many lawns he must mow to make $200. My son wants to earn money for a bike. He can mow 1 lawn for $18 but it costs him $3 for fuel for the lawn mower. How many lawns will he have to mow to earn $200. Make sure that you respond to at least one classmate as...

alpha decay tne menes valy widuery, Wnclcer the emitted alpha particles vary little (3 marks) The following expression holds for the half-life of an alpha emitter: (b) where C and D are (approximately) constant and D4 if Ea is in units of MeV Use this formula to calcuiate the ratio of the half-lives of Ra (a 5.685 MeV) and Ra (Ea 7.453 MeV). Compare your result with the ratio of the experimentally observed half-lives for 3 Ra (r 3.66 days)...
