WebEquation for beta minus emission The new nucleus formed from the decay is called the “daughter” nucleus (nitrogen in the example above) β + decay A β + particle is a high energy positron emitted from the nucleus β + decay is when a proton turns into a neutron emitting a positron (anti-electron) and an electron neutrino WebEquation of a circle. The general equation of a circle normally appears in the form \({x^2} + {y^2} + 2gx + 2fy + c = 0\). where \(( - g, - f)\) is the centre of the circle . and \(\sqrt {{g^2} + {f^2} - c}\) is the radius.. Notice that for the circle to exist, \({g^2} + {f^2} - c\textgreater0\). Look at the following worked examples.
