Question

(7.470 MeV/nucleon) for carbon-13 (m- 13.003355 u). An alpha particle (m 4.002602 u) is moving at 3.60 x 102 m/s. Find its kinetic energy. (4.30 x 1 x10 kg) cr Find its kinetic energy in Mev. (2.69 x 10 Mevy nd Find its momentum. (2.39 10 kg. m/s) Find its deBroglie wavelength. (2.77 x 10 10 m 0.277 nm) A stationary nucleus of protactinium-231 m 231.035879 u) decays by alpha radiation to a ucleus with a mass of 227.027747 u Write the full nuclear reaction He Ac) pa Find the energy released by this reaction. (5.151 Mery stationary, 0.679 MeV is released as heat, and assuming the actinium nucleus remains how much kinetic energy does the alpha particle have, in joules? (7.155x10 How fast is the alpha particle moving? (.468 x 10 m/s) 14) Refer back to problem 13 a) If he alpha particle is measured as only having a speed of 7.19 x 10 m/s, how fast is the actinium nucleus moving? (1.27 x 109 m/s) b) Now how much kinetic energy does the alpha particle have? (1.07 Me c) How much kinetic energy does the actinium nucleus have? (0.0190 Mel) d) How much energy would be left over to be released as heat? (4.06 Mevy 15) In a neutron capture reaction, a fast-moving neutron is absorbed into a nucleus, which then en splits into other nuclei. Aluminum-27 (m 26.981539 u accepts a neutron moving at 2.55 x 107 m/s, but then it splits into sodium-24 (m 23.990963 u) and helium-4 (m 4.002603 u). a) write the nuclear reaction. CiAl t Na t He) b) How much total mass do the reactants have? (27990204 u) c) How much total mass do the products have? (27.993566 u) or3.402 Mel) d) How much kinetic energy does the neutron have, in Mev? (3.404 e) How much extra mass do the products have? (0.003362 u) f How much extra energy does this represent? (3.132 Me kinetic energy is left g) Accounting for the energy of the incoming neutron, how much over for the reactants? (0.272 or 0.270 Me V)
