number 10. There is a star that has twice the mass of the sun. So here's the mass of the sun's. We have twice that, um, collapses and becomes a neutron store, and we wouldn't know what is the radius of it. We're supposed to treat it like an Adam. So the equation for the radius from Adam is this or not, which is a just a constant. So that's one port two times 10 negative 15 and a That's the mass number. Well, when a star becomes a neutron star, the protons electron combined make neutrons. So this is the mass of one neutron. So Mrs Conserved. So this whole mass of the star is now becoming neutrons. A mass number of it just be the number of neutrons there are. So that would be just this total mass. Oh, I'm just gonna be like that. The mass of this star divided by the massive one neutron up with those values in mess and start with this two times the mass of the sun 1.99 times 10 30 of divided by the massive one neutron. So this is basically telling me how many new transfer are raised to the 1/3 power and I get 15,958. That would be in meters. Um, well, you 236 figs called it like 16 point. Oh, cool, lumbers.
