The radionuclide `"^11C` decays according to `"_6^11C` `rarr` `"_5^11B` + `e^+` + `v` : `T_(1/2)` = 20.3 min .The maximum energy of the emitted positron is 0.960 MeV. Given the mass values: m (`"_6^11C`) = 11.011434 u and m ( `"_6^11B `) = 11.009305 u, calculate Q and compare it with the maximum energy of the positron emitted.
