1. In beta decay, an atomic nucleus emits an electron as it turns into another type of nucleus. A 2¹⁰Bi nucleus at rest decays to 210Po. Suppose the emitted electron moves to the right with momentum 5.60 x 10-22 kg m/s. The 210Po nucleus, with mass 3.50 x 10-25 kg, recoils to the left at a speed of 1.14 x 10³ m/s. Momentum conservation requires that a second particle, called an antineutrino, must also be emitted. Calculate the magnitude and direction of the antineutrino's momentum. 210PO 210Bi Before After e ?
